3DEvaluate Launched to Digitize 3D Printing Buying and Vending Process

The development of digital platforms and online solutions, especially to replace or transform in-person, hands-on business interactions, has accelerated due to the impact of COVID-19. Major public events and international travel are cancelled or uncertain for an extended period, leaving buyers and vendors unable to physically meet, or to gain first-hand information about hardware or software solutions, parts, and materials to evaluate and select the best fit for their business needs. We have already seen how major events such as TCT and IMTS, have introduced digital platform initiatives and content, such as IMTS Spark or TCT Asia Expo Reach, to try fill the gap or re-imagine what is most essential and effective in industry trade-shows.

Last year in July, 3DPrint.com had interviewed Gil Lavi, CEO of Israel-based 3D Alliances and bellwether for the industry, where he had shared his focus on being there for customers “to assist them with choosing the best solutions for their portfolio” and of providing “end-to-end solutions from design to end-use parts”. His efforts in connecting dozens of leading 3D printing start-ups with 3D resellers (to grow revenues, deploy and expand through global channels, obtain funding or talent) is what resulted in the world’s largest network of 1500 3D Value-Added Resellers (VAR) in 73 countries. Now, in response to COVID-19 impacts, 3DAlliances has launched 3DEvaluate, a platform to help buyers find, evaluate and select industrial 3D printing solutions, and for corresponding vendors to find and evaluate mature, capable buyers. The platform also serves as a third-party to streamline and optimize the purchasing process for both, buyer and vendor.

On the buyer side, the user can compare and evaluate different vendors and technologies within specific categories (FDM, SLA, SLS, Metals), receive sample parts or benchmark their own parts, and on selecting a supplier, can connect directly with them to complete the purchasing process. On the vendor side, the platform provides lead generation and qualification support, helps vendors make more efficient use of their marketing budgets, and enables them to interact with informed buyers who are mature and have already completed a thorough evaluation process, saving time and duplication of effort.

3DEvaluate also helps with verification. The two-sided platform does not indiscriminately list all 3D printing manufacturers seeking to sell. OEM manufacturers and vendors are not added to the platform on request, but are screened against certain criteria and profiled by 3DEvaluate to ensure vendors are reliable and professional before being added to the platform.

The platform serves to fundamentally speed up and simplify the buyer’s evaluation process prior to selecting an AM system. With buyers and vendors unable to travel and interact face to face, such online, remote third-party solutions accelerate the digitization in the buyer’s evaluation and selection process, bringing much needed efficiency as well as new capabilities to both buyers and sellers of AM systems worldwide. In addition, the platform also provides current information and educational content around 3D printing technologies and applications. It is clear that introducing such a platform (although it currently lists only FDM category, with SLA, SLS, and metal soon to come) in this macroeconomic environment, accelerates much-needed digitization in key areas of buyer-vendor interaction such as objective information, sampling, benchmarking, evaluation, purchasing and more.

It will be interesting to see how quickly 3DEvaluate is able to expand its reach and grow the number and types of vendors available across the technology categories. What would also be interesting to see is how such digital platforms compare with other product or solution comparison platforms, or complement third-party decision-making software platforms such as CASTOR (also from Israel) which evaluates both, the technical and financial feasibility of complex or low-volume parts for 3D printing. Both platforms sit in a critical point in the 3D printing value chain – helping customers, regardless of physical location, to objectively and efficiently, understand, evaluate and select the most suitable 3D technologies or vendors, to meet their specific business needs.

Evonik Announces Additive Pricing Analysis Software

Chemical giant and 3D printing materials company Evonik has introduced its first software for additive manufacturing (AM). The software is meant to reduce AM costs by helping users determine the proper 3D printing process depending on geometry, material and financial analysis of a part.

The technology behind the software was developed by Castor Technologies, an Israeli startup that Evonik Venture Capital invested in in October 2019. The software is framed as an auxiliary tool alongside CAD programs so that engineers can open existing CAD files, whether entire assemblies or a multitude of individual parts at once with the tool. The tool then performs an analysis of these parts and determines which are printable, how to make printable those that aren’t and the best material for printing them. It also estimates the cost and lead time and directs users to service bureaus that can print them.

The results are provided in the form of a report that includes the break-even point for AM as compared to traditional manufacturing processes. With this data, manufacturers are meant to be able to determine if and how 3D printing should be applied to the components they make.

While there are numerous methods for estimating the cost of printing a component using various AM services, a dedicated tool that determines how cost-effective using AM to fabricate a large number of parts compared to conventional methods does not yet exist on the market. Because additive is beginning to see widespread adoption and can introduce cost savings where appropriate, the tool has the potential to allow manufacturers to identify low-hanging fruit to introduce them to the technology before embarking on more involved additive projects. By giving potential users a deeper understanding of AM and its costs this could make AM much more of a viable option for many companies.

In one case study, Stanley Black and Decker used Castor’s technology to determine if any of its tooling should be produced via AM. One of the constraints was an eight-week-long lead time associated with having them made via traditional techniques. After uploading a number of tooling components, such as jigs and fixtures, Castor’s technology was able to determine high complexity, low volume parts that could be best suited for AM.

A wire lifter, for instance, was determined to be a good candidate for metal 3D printing, with an EOS M-290 system and maraging steel the system and material of choice. FIT America was selected as the service provider for the part. The software determined that the 3D printing cost for the tool would be $61 per part for 15 parts annually, compared to $120 per part using conventional manufacturing. This meant a nearly 50 percent cost reduction and the lead time was dropped from eight weeks to nine days.

“With the software, broader adoption of 3D printing at a commercial scale is now possible,” said Thomas Große-Puppendahl, head of the innovation growth field additive manufacturing at Evonik. “That will offer us better insights into customer needs and preferences in order to develop new “ready-to-use” materials.”

We don’t yet know exactly how much of Castor’s base platform is integrated into Evonik’s software; however, it is an interesting way for an additive materials manufacturer to expand to other products. In addition to its investment in Castor, Evonik provided its 20 years of additive materials expertise and ensured the accessibility of the tool to all industries. In turn, it’s possible that users might find Evonik’s polymer powders or filaments desirable for the production of their components.

3D Printing News Briefs: October 6, 2019

We’ve got lots of material news for you in today’s 3D Printing News Briefs, starting with a Material Development Kit from RPS. Polymaker and Covestro are releasing three new materials and EOS has introduced a new TPU material for industrial 3D printing. Moving on, CASTOR and Stanley Black & Decker used EOS 3D printing to reduce costs and lead time, and Velo3D is partnering with PWR to make high performance heat exchangers.

RPS Introduces Material Development Kit for NEO800

UK 3D printer manufacturer RPS just launched its NEO Material Development Kit, which was designed by company engineers to be used as a polymer research and development tool for its NEO800 SLA 3D printer. The MDK comes in multiple platform and vat sizes, and allows developers to work with different resin formulations, so that R&D companies can work to develop a range of polymers that are not available in today’s industry. Users can print single layer exposure panes with Titanium software and the 1 liter vat in order to find the photo-speed of the formulation they’re developing; then, tensile testing of different material formulations can commence. Once this initial testing is finished, developers can scale up to the 13 liter vat – perfect for 3D printing prototype parts for use in optimizing final configuration settings.

“This NEO Material Development Kit now opens the door for large industrial chemical companies such as BASF, DSM and Heinkel to push the boundaries of UV photopolymers,” said David Storey, the Director of RPS. “The industry is looking for a quantum jump in materials to print end-user production parts from the stereolithography process.”

New Polycarbonate-Based Materials by Polymaker and Covestro

Advanced 3D printing materials leader Polymaker and polymer company Covestro are teaming up to launch three polycarbonate-based materials. These versatile new materials coming to the market each have unique properties that are used often in a variety of different industries.

The first is PC-ABS, a polycarbonate and ABS blend which uses Covestro’s Bayblend family as its base material. Due to its high impact and heat resistance, this material is specialized for surface finishings such as metallization and electroplating, so it’s good for post-processing work. Polymaker PC-PBT, which blends the toughness and strength of polycarbonate with PBT’s high chemical resistance, is created from Covestro’s Makroblend family and performs well under extreme circumstances, whether it’s subzero temperatures or coming into contact with hydrocarbon-based chemicals. Finally, PolyMax PC-FR is a flame retardant material that’s based in Covestro’s Makrolon family and has a good balance between safety and mechanical performance – perfect for applications in aerospace motor mounts and battery housings.

EOS Offers New Flexible TPU Material

In another materials news, EOS has launched TPU 1301, a new flexible polymer for industrial, serial 3D printing. Available immediately, this thermoplastic polyurethane has high UV-stability, great resilience, and good hydrolysis resistance as well. TPU materials are often used in applications that require easy process capabilities and elastomeric properties, so this is a great step to take towards 3D printing mass production.

“The EOS TPU 1301 offers a great resilience after deformation, very good shock absorption, and very high process stability, at the same time providing a smooth surface of the 3D printed part,” said Tim Rüttermann, the Senior Vice President for Polymer Systems & Materials at EOS. “As such the material is particularly suited for applications in footwear, lifestyle and automotive – such as cushioning elements, protective gears, and shoe soles.”

You can see application examples for TPU 1301 at the EOS booth D31, hall 11.1, at formnext in Frankfurt next month, and the material will also be featured by the company at K Fair in Dusseldorf next week.

CASTOR, Stanley Black & Decker, and EOS Reduce Costs and Lead Time

Speaking of EOS, Stanley Black & Decker recently worked with Tel Aviv startup CASTOR to majorly reduce the lead time, and cost, for an end-use metal production part that was 3D printed on EOS machinery. This was the first time that 3D printing has been incorporated into the production line of Stanley Engineered Fastening. In a CASTOR video, EOS North America’s Business Development Manager Jon Walker explained that for most companies, the issue isn’t deciding if they want to use AM, but rather how and where to use it…which is where CASTOR enters.

“They have a very cool software in which we can just upload the part of the assembly CAD file, and within a matter of minutes, it can automatically analyze the part, and give us the feasibility of whether the part is suitable for additive manufacturing or not. And in case it is not suitable, it can also let us know why it is not suitable, and what needs to be changed. It can also tell us what is the approximate cost, which material and printer we can use,” said Moses Pezarkar, a Manufacturing Engineer at Stanley’s Smart Factory, in the video.

PWR and Velo3D Collaborating on 3D Printed Heat Exchangers

Cooling solutions supplier PWR and Velo3D have entered into a collaborative materials development partnership for serial manufacturing of next-generation heat exchangers, and for the Sapphire metal 3D printer. PWR will be the first in the APAC region to have a production Sapphire machine, which it will use to explore high-performance thermal management strategies through 3D printing for multiple heat exchange applications. Together, the two companies will work on developing aluminum alloy designs with more complex, thinner heat exchange features.

“PWR chose Velo3D after extensive testing. The Velo3D Sapphire printer demonstrated the ability to produce class-leading thin-wall capabilities and high-quality surfaces with zero porosity. Velo3D and PWR share a passion for pushing the limits of technology to deliver truly disruptive, class-leading, products. We are a natural fit and look forward to building a strong partnership going forward,” said Matthew Bryson, the General Manager of Engineering for PWR.

“Heat exchanger weight and pressure-drop characteristics have a huge impact on performance and are significant factors in all motorsport categories. Using additive manufacturing to print lightweight structures, enhancing performance with freedom-of-design, we have the ability to further optimize these characteristics to the customer’s requirements whilst providing the necessary cooling. The broad design capabilities and extremely high print accuracy of the Velo3D Sapphire 3D metal printer will help us optimize these various performance attributes.”
