Is This the Best Way to Manually Post-Process an FDM 3D Printed Part?

Researchers Jinjin LiuHai GuBin LiLu ZhuJie Jiang, and Jie Zhang from the Nantong Institute of Technology and Jiangsu Key Laboratory of 3D Printing Equipment and Application published a paper, titled “Research on Artificial Post-Treatment Technology of FDM Forming Parts,’ about using manual post-processing on 3D printed parts made with FDM technology, which has a low molding accuracy that can cause stair-stepping.

“Due to the “step effect”, the printed parts have rough surface, obvious stripes, poor surface quality, and cannot meet the customer’s or specified requirements, so post-processing is very important. This paper mainly studies and summarizes the manual post-processing technology of FDM printed parts, and provides the specific implementation method of post-processing, providing reference for the post-processing of FDM formed parts and other forming processes,” the researchers wrote.

Figure 2. The vase model.

In order to “further improve the surface quality and strength” of 3D printed models, post-processing is often necessary. Some of the more common methods of post-processing FDM formed parts include:

  • Chemical treatment with organic solvent
  • Heat treatment
  • Mechanical treatment with a sander or grinder
  • Surface coating treatment

In this paper, the researchers focused on a manual post-treatment process, which requires several items to work properly, such as a spray pen air pump with air storage tank, a coloring pen and tool set, gloves, a mask, water-diluted solvent in a solvent bottle, quick dry small fill soil, 80 to 3000 mesh sandpaper, a cleaning agent, a file, and others.

The team fabricated a post-treatment vase model as an example, using PLA material and an Einstart 3D printer. Once the vase was printed, they removed the plate with the model on it from the printer.

Figure 4. Model finished printing. Figure 5. Demolition of support.

“…the model is smoothly removed from the bottom plate with a shovel, and then to check whether there is strain concentration model, relatively weak parts with small first stripping knife to spin out the model and the support, and then has a long nose pliers clamping a direction support, applying a constant force, the location of the tiny support can use the file to remove,” they wrote.

To clean up a rough surface, the researchers noted that you can use low mesh sandpaper to sand and polish it. The model and the low mesh sandpaper should be immersed in water and sanded along the model’s texture, as this can both extend the sandpaper’s life and smooth out the model’s surface.

Then, they moved on to a technique called quick dry small fill, which involves the addition of a small amount of filling material to gaps in the model; then, the fill is evenly daubed with a hard scraper.

Figure 7. Apply small patch of soil evenly. Figure 8. Polished to make it smooth.

“Then wait for 30 seconds, after filling soil has hardened, using 1200 mesh to 1500 mesh sandpaper in, as shown in figure 8, If there are still tiny grooves and repeat the above steps,” the researchers wrote. “To be in addition to the groove after no large-area fill soil, feel smooth, can proceed to the next step.”

The next step is spray can water fill soil spraying. First, the model’s surface should be washed with water, and then the spray pot is used to fill the soil, before the model is wiped with a non-woven cloth and sprayed at “the ventilated position,” keeping the nozzle at about 20 cm and uniformly spraying the model one to three times, quickly.

“Generally, choose gray spray pot water to fill the soil, because gray is a neutral color,” the team explained.

Figure 10. High mesh sandpaper grinding.

Once the water is sprayed and the soil is filled, air drying takes place. Then, 2000-3000 high-mesh sandpaper is applied for “slight grinding” along one direction, before moving on to the coloring phase.

The 3D printed, polished and processed model should first be washed and dried before pigments are applied. A spray gun can be used to add either a base color or one that covers a large area of the model; you’ll need a 1:2 ratio of diluent to pigment for spraying, and you should be able to adjust the amount of air injection while you’re spraying.

“Brushes of different thicknesses and sizes can be used to paint the details,” the team wrote. “It is accessible to use 00000 pens to paint the detailed parts of the figures, or use different widths of the cover tape to cover and then spray the spray gun to paint.”

Once the paint and spray paint have dried completely, you can uniformly spray protective paint on the model; the research team used B603 water-based extinction for their 3D printed vase.

The team shared a few more notes on making the post-treatment process run smoothly, such as the importance of using software to reduce the amount of unnecessary support structures, coating the print plate with a thin layer of glue to prevent deformation, and observing the model while it’s being printed.

Figure 13. The vase is finished after processing.

“Secondly, in the manual post-processing should look to the protection work, grinding water mill is the best way to model processing, be patient, 80-2500 mesh, use each mesh sandpaper required time from long to short, low mesh sandpaper grinding along the texture of the model, high mesh sandpaper grinding should be turned around,” the researchers concluded. “When mixing colors, you should understand in advance the relationship between light and shade, brightness and purity of various colors, warm and cold color selection, etc.”

They noted that “the degree of difficulty” for post-processing methods, and the methods themselves, can vary with different 3D printing technologies – what works for FDM may not necessarily work for SLA, and so on.

Why Automated Post Processing Makes Manufacturing With 3D Printers Possible

In Material Extrusion (FDM), we can now use inexpensive machines to make dimensionally accurate & tough parts in various materials at low cost. These parts can fulfill many industrial and manufacturing applications bar one glaring defect. Material Extrusion (FDM) parts are often ugly, and layers can be seen on the rough parts. FDM parts and materials are improving all the time; parts are getting smoother and better looking out of the machine. Clusters of FDM machines bring throughput and versatility and have begun to be used to manufacture parts at scale.

With Selective Laser Sintering (powder bed fusion), one can make thousands of individual parts in many different geometries. Highly detailed polyamide SLS parts have been used for tens of thousands of surgical guides and have found many industrial applications. All parts have to be depowered and cleaned of excess powder, however. Additional steps, such as mechanical finishing are often needed to close the open surface texture of SLS parts.

With Dye Mansion depowdering is combined with surface improvement and coloring to make parts more world proof.

With SLA (stereolithography, vat polymerization) tens of millions of molds have been made for jewels with millions more being used in the dental industry. Additionally, millions of intermediates have been made for aligners. Direct SLA parts in hearing aids have revolutionized the In The Ear hearing aid industry, winning the market in customized fit ITE hearing aids. And yet, every SLA part has to be cut off of supports manually, and most have to be filed down afterward. Parts have to be conveyed to a washing station and a UV flash machine.

Meanwhile, in the SLS world, the future of manufacturing consists of a man with a brush brushing off powder from a part. It won’t surprise you that a third of part costs are perhaps due to finishing and post finishing parts. We boast of machines that can, in a day, make a new part, only to casually leave out that this part may spend another day in a tumbler. We jump on the gleeful subsidy bandwagon that is Industry 4.0 while a lot of the cost of 3D printed parts is in conveyancing.

Additive Manufacturing Technologies‘ automated surface finishing colors and finishes in one step.

Significant part costs comprise of people carrying parts around a factory. A woman leans over, looks at a piece of paper, matches the part, carries it to her station and then later puts it on a tray where a colleague takes it to a new station. This is Industry Bore.0, not 4.0. And metal printing? Like all things, it makes the polymer part of our industry look easy. Parts have to be sawed off by hand, and a number of post-processing stations always pay a part: from HIP to EDM to shot peening to destressing to spending a week in a tumbler it often needs to happen to your metal part.

We can not ask industrial manufacturing firms to learn new ways of thinking, master design for additive, change parts in their inventory and take on new unknown risks in return for a future where parts are marched around a “factory.” I say factory partially in jest because currently manufacturing with 3D printing is much closer to a collective of be-dreaded sandal-wearing artisanal vegan soap makers than actual manufacturing.

Rosler’s AM Post Processing Line of machines remove powder, support and structures.

Imagine us, some hippie collective with handcrafted bamboo bowls trying to sell our way to the Six Sigma people? Just change everything; it will be great. Hope is the new one error per ten million. Do you want a Craft aircraft? Do artisanal aero engines sound like a good idea to you? Would you like to take a trip to Mars on a handcrafted rocket? Would you like your next hip to be made with love? Or would you prefer it to have things like quality control? We’re currently selling a dream to manufacturers that for many applications, we can not turn into a reality.

Post Process showing you parts before and after their process.

What can make 3D printing for manufacturing real? Automated Post Processing. By automating the entire post-processing chain, we can dramatically lower the part costs of 3D printed parts. We can make many more business cases worthwhile by making 3D printed parts significantly cheaper. By automating conveyancing throughout the plant, we can dramatically reduce the overall cost at high throughput. By offering post finishing to improve the surface quality of parts, we can make better looking and better-performing parts. Consumer-friendly and industry-friendly parts can ensure that the adoption of 3D printing is more rapid. The combination of automated post-processing with 3D printing will let parts be produced close to the consumer in wealthy countries at a reasonable cost. Improved post finishing processes will improve surface quality and let 3D printed parts be deployable for many more applications. If we integrate automated QC and QA processes into post-processing setups, we can genuinely offer manufactured 3D printed parts to many industries. Many firms are looking into automating the entire post-processing chain. From Post Process to Rosler, Additive Manufacturing Technologies and Dye Mansion, it is these companies that will unlock manufacturing for us all.

University of Pittsburgh Develops Depowdering Machine for Metal Printing

The University of Pittsburgh has developed a depowdering solution for metal 3D printers that could significantly reduce the cost of 3D printed metal parts. Lead by Professor Albert To, a team of undergraduates has made a gyroscope-based depowdering machine. Professor To is the leader of the AMRL, or ANSYS Additive Manufacturing Research Laboratory, at Pitt and also runs the MOST AM lab, which is a cutting edge lab that develops 3D printing simulation tools. To’s ANSYS AMRL teams decided to attempt a much more hands-on project, however, with this depowdering machine, the Pitt Depowdering Machine.

Why is depowdering important?

Post-processing accounts from anywhere from 30 to 60% of the cost of a metal 3D printed part. Far from a machine driven push-button process metal printing technologies such as Powder Bed Fusion require a high degree of manual labor. Files have to be prepared by hand, support strategies have to be thought up builds have to be nested and material has to be loaded. Once the build is done the parts have to be depowdered. This usually involves a brush and vacuum cleaner. Then parts will also have to be destressed, sawed off, tumbled and may require EDM, CNC, precipitation hardening, shot peening etc. All the while a human operator will be carrying the parts around a factory. The actual 3D printing metal process is still rather artisan even though we’re promising the world that we will make millions of car parts cost-effectively. To bridge this gulf automation will be necessary. Additive Industries is including post-processing steps in the machine others are making lines of machines aimed to reduce the cost. The cool thing about adding automated conveying, destressing, EDM wire, and other systems to an existing line is that these add ons can be used to reduce costs in existing lines and be used with machines from several vendors. All of metal 3D printing’s promises and promise will have to be fulfilled through the nuts and bolts of improving and creating industrial processes. Automated post-processing is a key element of that so Pitt’s machine is very timely to say the least.

Pitt Depowdering Machine

To tells 3DPrint.com,

“The depowdering machine employs a gyroscope design that can rotate the AM build 360 degrees in two orthogonal directions. There is a vibrator that is attached to the build and vibrates the build at a high frequency so that the powders are loosened up and come out from the build as the gyroscope is rotating through different angles. There is a funnel below the gyroscope that is used to collect all the powders coming out from the build. The machine is equipped with two sieves at the bottom of the funnel to sieve the powders to the right size for re-use.”

Such a device has the power to reduce a lot of carrying around and operator time. The speed at which one could depowder a build varies enormously but as per the team’s data they should have a huge productivity increase in terms of time over existing users.

“Typically, we put an AM build on the machine for 15-30 minutes depending on the size of the parts,” To said.

That’s not all, however: the machine may also be more efficient than existing processes.

“In one test, the machine shook out 5 more grams of powders after the technician did his best to depowder manually with the aid of a vibrator.”

A vibrator in a metal 3D printing context is a rotary or tub vibrator or a vibratory finisher which is a machine where parts are mixed in with media and then vibrated to de-clog and remove powder.

If the Pitt machine performs like this in continuous operation the savings could be significant.

To says,  “We are still evaluating whether to commercialize the machine and talking to other people about it at the moment.”

We would strongly encourage them to commercialize this machine. Any in line device that could really reduce the costs of 3D printed parts would make many more metal 3D printing applications possible.

 

3D Printing News Briefs: March 16, 2019

We’re starting with 3D software and medical 3D printing in today’s 3D Printing News Briefs, and then moving on to stories about some cool 3D printed projects. Sinterit has updated the software for its SLS 3D printers, and Deutsche Bahn is increasing efficiency with software solutions by 3YOURMIND. Medical 3D printing is on the rise in Sri Lanka. A designer whose work we’ve previously covered used Carbon technology to 3D print a unique pair of heeled shoes, and an Indian company used 3D printing to reduce the production time for a 6 ft superhero.

Sinterit Releases New Software Update

Desktop SLS 3D printer manufacturer Sinterit just released a new update for its Studio software, which all Lisa and Lisa Pro 3D printer users will now be able to access for a better consumer experience. The update gives these users a lot of positive changes, including more detailed and precise 3D printing with its PA11 Onyx and TPU Flexa materials and optimized slicing, which makes it easier and faster to manipulate models, while also using less RAM.

Sinterit has also made it possible to stream video via WiFi from its 3D printers’ cameras, so users can keep an eye on their prints remotely. In addition, the 3D printers now have an easier step-by-step guide on the screen to make the startup procedure smoother, and a new “About” button on the menu is helpful for optimized model preparation inside Sinterit Studio.

Deutsche Bahn Using 3YOURMIND Software Solutions

German railway company Deutsche Bahn (DB) has been working hard over the last five years to continue developing its 3D printing division. Now, DB has joined industrial 3D printing software solutions provider 3YOURMIND in a strategic partnership in order to increase the efficiency of its 3D printing processes, and also determine possible 3D printing applications from around its company in order to assemble a digital spare parts warehouse. The Berlin-based company’s software platforms allow customers to exploit 3D printing potential with digital workflows, and 3YOURMIND supports DB’s ambition to expand its own additive manufacturing reach.

3YOURMIND’s software will give DB employees access to a simple digital interface so they’re able to quickly submit new ideas for 3D printable parts based on applications they encounter every day. Then, the platform provides an analysis and identifies uses cases with the highest production potential, before DB experts shine a spotlight on the employees and choose the best projects to send into production.

Medical 3D Printing in Sri Lanka

According to Dr. Rajitha Senaratne, the Health Minister for the South Asian island of Sri Lanka, 3D printing for health applications will now be available for the first time in the country beginning this month at the National Hospital of Sri Lanka (NHSL). Minister Senaratne made this announcement in Colombo – the country’s largest city – at the 26th Annual Scientific sessions of the College of Medical Administrators, stating that doctors can provide more personalized care by using modern technology like 3D printing.

In conjunction with this announcement, RCS2 Technologies, the country’s sole 3D printer manufacturer with its Thrimána line, will be working with the country’s Ministry of Health to start up a 3D printed prosthetic manufacturing project.

3D Printed Generative Heels

Talented designer Masaharu Ono, currently working for Japan’s DiGITAL ARTISAN.inc, is well-known for his creative 3D printed projects in both the fashion and technology worlds. Now he’s back in the fashion world with a 3D printed pair of high heels that you’ve got to see to believe. On the artisanal project “Generative Heel – Formless” for DiGITAL ARTISAN, Ono worked with casting company Castem, chemical manufacturer JSR, and 3D printing company Carbon to create the sky-high heels.

“This is concept model for mass customization, but I just getting ready, I will sell it as soon as possible,” Ono told 3DPrint.com.

3D Printed Window Spiderman

An Indian manufacturing company by the name of STPL3D received an unusual order from a traditional fine arts manufacturer: an extremely detailed, 6-foot Spiderman sculpture for the opening of a new entertainment store. Typically, a project like this would take closer to two months, but STPL3D’s given deadline was just one week away. Using 3D printing, the company was able to complete it in just four days, which helped lower the cost and weight of the sculpture as well. Digital sculpting was used to modify an open source file to better fit the client’s needs.

“Our production team wanted to take full advantage of our array of 15 FDM machines so we could finish the project before the timeline, so we divided the 6 ft* 4 ft sculpture into 20 parts, then our post-processing team assembled the spiderman in 6-7 hours with plastic welding and glue to bring it in real shape that was required by the client,” Hardik Prajapati of STPL3D told 3DPrint.com.

“Post processing is always fun and all about teamwork. Our artistic and post-processing team played a major role in finishing the project that had matched our client’s expectation.”

Interview with Kai Witter Looking at the Business Case for DyeMansion Depowdering and Dyeing Powder Bed Fusion Parts

From file to software to machine to finished part takes a design along a path through many different vendors, formats, processes, and interactions. We as an industry are trying to manufacture, reliably with a disparate set of tools and technologies. In between ones and zeroes and finished product we have many crucial steps that get an idea closer towards becoming a thing. Depowdering in powder bed fusion (SLS, selective laser sintering) and other powder technologies such as Multijet Fusion was once seen as a cost center. An annoying laborious task that had to be done. A block of powder with 3D printed parts in it had to be sieved, hand cleaned for the parts to be sorted, matched and shipped. As much as a third of 3D printed part cost is manual labor. You can appreciate this is you see how this depowdering process works and just how labor intensive it is. Companies have traditionally offered tumblers and other surface treatment solutions to ameliorate this and improve surface finish. A few years ago a company wanted to change this. Rather that seeing depowdering as a cost center they saw it as a part of a series of process steps that elevated a mere polymer shape into a consumer-friendly part. Rather than just selling a machine that performed an operation this team, the DyeMansion team developed three different machines that while working together could depowder, surface treat and dye a part. A process chain with a high degree of automation and tooling meant to work together in a highly optimized way. We covered the company before when they raised a series A of five million, when they launched in the US, when they won an award, when they went to AMUG, when they showed at Formnext in 2016 and when they got investment previously.

 

The Powershot C parts cleaning machine, step 1.

When I got started dyeing SLS parts was done in those electric soup kettles that you see at catered events. We used Dylon meant for coloring t-shirts and had a person stirring by hand. Parts would dye unevenly becoming dark blue on one side and lighter on the other. It was a mess always and cauldrons full of red and blue dye were everywhere. It didn’t exactly feel like the future of manufacturing rather more the future of witchcraft. And that is precisely where we are now. We’re going from spells, hope, exotic ingredients and promises to ISO, GMP and repeatable production. What do we see? Everyone wants to make or sell 3D printers, lots of people are developing software and many sell materials but only one firm is developing a line of post-processing solutions that in an integrated way depowders, cleans and surfaces parts. The three machines work in tandem and are rather confusingly named the Dyemansion Powershot C, Powershot S and Dimension DM 60. The Powershot C is not a camera but then again there are precedents in the 3D printing industry in having names similar to camera names. The C cleans parts and depowders them using movement and ionization and damaging parts less than alternatives, while the S is a blasting cabinet with a high degree of automation that gives parts a more closed and more uniform surface texture and structure; and the DM 60 is the dyeing unit.

The S, the second step for surfacing.

All in all I’m a huge believer that in a Gold Rush sell picks and shovels and have heard great things about the labor-saving capabilities of these units from friends. We spoke to Kai Witter who after a long 3D printing career became the sales manager at DyeMansion and is helping bring the technology to manufacturers worldwide.

The DM60 Dyeing unit

Kai said that Dyemansion is, “A company that’s evolving from a startup to a global market leader who offers value-adding post-processing solutions for AM plastic parts manufacturing. We are the challenger of the status quo, together with AM printer manufacturers we challenge injection molding industry.” 

How much labor does your depowdering station save? If I did 5 full builds a week, how much money or how many hours would I save?

As usual, all this is application dependent. Let’s look at saved hours as cost of conventional manual blasting units and staff costs vary a lot:

The average cleaning time of one batch with PowerShot C is 10 mins

  • Let’s assume 100 mid-sized mid complex geometry parts (loading volume is a full HP4200 job or 75% of a EOS P3x Job). So we assume 5 Runs/week
  • Loading and unloading each 2 mins, in total 4 Mins

Powershot C:           

  • 4 mins (loading & unloading)
  • 5 runs a week
  • 50 weeks
  • 4 m(ins) x 5 (runs) x 50 (weeks) = 1000 mins or 16,5 hrs 

Conventional manual blasting:

  • 3 mins average. cleaning time/part
  • 4 mins (loading & unloading)
  • 5 runs a week
  • 50 weeks
  • Cleaning: 100 (parts) x 3 (mins) x 5 (runs) x 50 (weeks) = 75.000 mins/1.250hrs
  • Loading & unloading: 4 (mins) x 5 (runs) x 50 (weeks) = 1.000 mins
    • 76.000 mins or 1267 hrs
  • 16 vs 1267 hrs

  • Powershot C saves 1251 working hours. 

So it is three units that work together? How do they work and how much do they cost?

The three unity combined build an integrated workflow, so called ‘print-2-Product’ workflow to turn 3D printed raw parts into high value products in 3 hours only. Automated, efficient and reproducible.

  1. Powershot C: Cleans parts in 10 mins only, without damaging the surface. Compared to manual cleaning we assure the sensitive surface of 3D printed raw parts is not damaged from too much blasting pressure and broken or worn blasting media.
  2. Powershot S: Refines the surface of the raw parts with a smooth touch, matte-glossy finish and improves scratch and water resistance of the parts in 10 mins only. The PolyShot process prepares the part for homogeneous dye absorption that leads to an even color image over the complete surface of each part and all the parts.
  3. DyeMansion DM60: Is the fully automated Dyeing system to fit out the parts with any color required. The DM60 adds the final value to parts. Launched at tct 2018 we have added 170 standard RAL colors to our out of the box portfolio. Any other color, suiting the material and required finish of the part can be developed at DyeMansion in only 3-4 weeks

 

So how does it work as an investment? 

“If we assume industry standard of 5 years depreciation and the calculation above (saving 1250 hrs pa) customers have a positive impact on their bottom line after the 1st month of using the Powershot C.” 

Why is damage prevention so important?

“Our infiltration Dyeing process does not add a layer to the raw part as we know it from spry painting. They dye connects with the material and avoids another process step to create a nice surface. Further it enables to finish printed textures, eg leather structure alike textures as used for automotive or aerospace interior parts.”

What does the ionization do?

“It removes the static charge of the parts and thus avoids that parts attract loose powder residue in the cabin atmosphere back to the parts. It ensures that parts are really clean.”  

Why is a homogenous surface quality important?

“A homogeneous dye absorption is the prerequisite for an even color image of the end use part. We finish the printed part including printed textures without any impact on the geometry. Neither the Powershot C (Step 1), nor Powershot S (Step 2) are abrasive and (Step 3) the dyeing, does not add a layer to the part like spray painting does. Thus, an additional process ta accomplish high quality end-use part surface is not required.”

How does the second step work?

“The PolyShot surfacing is a proprietary surface compression process with plastic media to even out the heterogeneous surface roughness and porosity of 3D Printed plastic parts.”

Why is the feel of the product important?

People are used to comparing parts with what they know, such as Injection molded parts. Rough surfaces don’t create an image of quality, they are scratch and dirt sensitive.

It is all about perception and mind change. The high-quality perception of 3D printed parts on a manufacturing level, even if the visual appearance may not be relevant for the functionality (functional end-use parts or functional protoytypes) is a prerequisite to open up more and more applications that are injection molded today, maybe only because of the feel.

Does it make it feel more luxurious?

I would not call it luxurious. I think it meets injection molded standards, at least. Nevertheless, some of our customers from the life style industry describe our matte-glossy look as more valuable than the typical shiny look & feel known from Injection molded parts.

How long do these steps take?

  • Step 1 – Powershot Cleaning => 10 mins
  • Step 2 – Polyshot Surfacing => 10 Mins before the dyeing and optionally a few minutes after the dyeing to increase the matte-glossy look & feel.
  • Step 3 – Dyeing => 90 to 150 mins

How does the coloring process work?

“We have developed an automated, flexible, geometry independent infiltration process where the parts are constantly moving in a water bath. The cartridge is filled with the recipe (reflecting color, material and finish) to accomplish the required color. Further a RFID chip on the cartridge defines the required process parameters such as temperature curve, holding time and pressure that is required. The dye connects with the part as a chemical reaction.

The recipe and DM60 process together make reproducible, high quality end-use parts. The operator just scans the RFID information, adds parts and Cartridge to the part basket of the DM60 and presses start. After 90 – 150 mins the DM60 process is finished including a cleaning and fixation step. When the DM 60 door opens, parts a free of dye.”

 How much are the cartridges and how do they work?

“The cartridge price varies between €40 and €105 depending on the required volume of the dyebath.

The cartridge contains the recipe for the required color and the RFID Chip for the required DM60 process parameters. The cartridge is inserted into a shaft at the bottom of the part basket. The cartridge is opened and the dye mixed with the water when the DM60 has reached the process conditions. After 90-150 minutes the parts are ready just a little moisture (Dye free) from the cleaning a fixation phase remains.”

How many colors can I do?

“We have around 200 Colors of the shelf and have developed more than 400 individual colors for customers, such as corporate colors, creative colors and for special finishes. We can develop almost any color within 3-4 weeks development time.The price is €250 for a defined color from a color system such as Pantone and €750 form a reference part.”

What are some of the interesting things customers are doing with your products?

This is always the toughest questions. There are so many interesting and mind-blowing applications with DyeMansion. But the competitive advantage our customers accomplish prevents them from making it public. Famous parts are automotive and Aerospace interior parts, prothesis and orthoses, medical devices and instruments, Eyewear frames and top-notch sports shoes with 3D Printed and DM finished midsoles.
