3D Printing News Briefs: March 23, 2019

We’ve got plenty of business news to share in this week’s 3D Printing News Briefs, but first we’ll start off with something fun – the winners have been announced for this year’s Additive World DfAM Challenge. Moving right along, BeAM is now a Tier 2 member of the ARTC, and PostProcess Technologies has announced improved processing times for SLA resin removal. Protolabs is offering new anodizing services, in addition to teaming up with Wohlers Associates, and Arkema will soon open a new PEKK plant in the US. Continuing with new things, a new AM digital career growth platform just launched, and there’s a new open project call for the European AMable project. Finally, GoPrint3D is the new UK distributor for Mayku and its desktop vacuum casting unit.

Winners Announces for Additive World DfAM Challenge 2019

This week during an awards dinner at the Additive World Conference in Eindhoven, Ultimaker’s Steven van de Staak, Chairman of the 5-member jury for this year’s Additive Industries’ Design for Additive Manufacturing Challenge, announced the two winners and their “inspiring use cases of industrial 3D metal printing.”

Obasogie Okpamen from The Landmark University in Nigeria won first place, and an Ultimaker 2+ 3D printer, in the student category for his Twin Spark Engine Connection Rod. While the connection rod that he redesigned for an Alfa Romeo 75 Twin Spark Turbo engine has not yet been fully tested, he won “because of the example it sets” for distributed localized manufacturing of spare parts with 3D printing. Dutch company K3D took home first place, and an Ultimaker 3, in the professional category for the Dough Cutting Knife it developed for Kaak Group, a leader in the bakery equipment world. The team integrated mechanical parts into the design, which can be 3D printed without any support structures and has improved functionality. The knife sits in a dough extrusion line and due to its light weight less knives and robot arms can do the same amount of cutting. This means that the extrusion line itself is cheaper. Furthermore the knife has been optimized for a cleaner cut with less knife sticking to the dough.

BeAM Joins Advanced Remanufacturing and Technology Centre

Membership agreement signing ceremony held in ARTC

France-based BeAM, which has subsidiaries in the US and Singapore and was acquired by AddUp this summer, is now partnering with the Advanced Remanufacturing and Technology Centre (ARTC) as a Tier 2 member in an effort to expand its research activities in southeast Asia. The center provides a collaborative platform, which will help BeAM as it continues developing its Directed Energy Deposition (DED) technology with companies from the aerospace, consumer goods, marine, and oil & goods sectors.

This summer, BeAM, which also became a member of the Aachen Centre for Additive Manufacturing earlier this month, will install its Modulo 400, featuring a controlled atmosphere system, at ARTC, so other members can safely develop non-reactive and reactive materials. The two will also work to develop process monitoring systems that can expand DED’s range of applications.

PostProcess Technologies Announces New Solution for SLA Resin Removal

A new and improved solution for SLA resin removal by PostProcess Technologies vastly improves process times by 5-10 minutes – quite possibly the fastest on the market. The system can clean up to five times as many parts before detergent saturation when compared to solvent resin removal, and is part of the company’s automated AM post-print offering. The patent-pending solution, which also reduces environmental hazards and preserves fine feature details, was validated with eight different resin materials in several production environments, and uses the company’s proprietary AUTOMAT3D software and SVC (Submersed Vortex Cavitation) technology in the DEMI and CENTI machines.

“PostProcess’ latest innovation of the most advanced SLA resin removal solution in the world reinforces our commitment to providing the AM industry with transformative post- printing solutions enabling the market to scale. SLA is one of the most popular 3D printing technologies in the world. No matter what volume of printing, any SLA user can benefit from the remarkable efficiencies of our solution’s decreased processing time, increased throughput, increased detergent longevity, and improved safety,” said PostProcess Technologies CEO Jeff Mize. “PostProcess has designed the world’s first complete SLA resin removal system, available only from the pioneers in forward-thinking 3D post-printing.”

The new SLA Resin Removal technology will be on display at PostProcess booth P21 at the upcoming AMUG Conference in Chicago. You can also read about it in the company’s new whitepaper.

Protolabs Offering Aluminum Anodizing; Partners with Wohlers Associates

As part of its on-demand production service, digital manufacturer Protolabs is now offering aluminium anodizing in response to demand from customers in need of a single-source solution. Anodizing forms a protective oxide layer by applying a thin, protective coat to the part, which increases abrasion resistance and creates a barrier against corrosion. The company will be offering two levels of this service for Aluminum 6082 and 7075: hard anodizing to ISI 10074 for parts requiring protection from harsh environments, and decorative anodizing to ISO 7599 for parts that need an aesthetic finish. All parts will be sealed, unless they need to be painted post-anodizing.

“Talking to our clients, we realised that if they needed to anodise an aluminium part it was often difficult for them to source and then manage a supplier. They not only have to do all the research and then raise a separate purchase order, but often find that the supplier only accepts large quantities of parts in an order, which isn’t great for low volume runs,” explained Stephen Dyson, Special Operations Manager at Protolabs.

“Keeping the entire production process with a single supplier makes perfect sense for manufacturers. It means they can get their finished parts shipped in a matter of days and our technical team can advise them through the entire process, right from the initial design of the part to the best approach for the final anodising finish.”

In other Protolabs news, the company is partnering up with AM consultants Wohlers Associates to jointly hold an immersive course on DfAM. The class, which is invitation-only, will take place over the course of three days near Raleigh, North Carolina, and will end at Protolabs’ 77,000 sq. ft. 3D printing facility. Olaf Diefel, Associate Consultant at Wohlers Associates, and Principle Consultant and President Terry Wohlers will lead the discussion, in addition to being joined by several Protolabs engineers who are skilled in polymer and metal 3D printing.

“Designing for AM offers unique challenges and opportunities not found in traditional design methods. Protolabs brings tremendous depth of expertise and leadership in 3D printing. We’re thrilled to work together to equip attendees with technical skills and manufacturing knowledge needed to unlock the full potential of additive manufacturing,” said Wohlers.

Arkema Opening New PEKK Plant

Arkema, one of the largest specialty chemical and advanced materials developers, has been busily producing polyetherketoneketone, or PEKK, in France. But this coming Monday, March 24th, it is celebrating its new Kepstan PEKK plant near Mobile, Alabama with a ribbon-cutting ceremony.

The durability and customizable abilities of PEKK make it a good material for a variety of 3D printing purposes. Monday’s event will take place from 10:30 am to 1:30, and will also include VIP comments and lunch. The increased volume of this PEAK material will shake up the high-performance polymer market making PEKK a viable alternative to PEEK and PEI.

New AM Digital Career Growth Platform Launched

A free interactive platform to help AM professionals enhance their skills and fulfill career opportunities is now launching. i-AMdigital, which counts HP as one of its backing partners, is a joint venture between AM industry recruiter Alexander Daniels Global, digital venture company TES Network, and web and UX design company De Wortel van Drie. The platform was created to develop a growing AM talent pool, and uses smart matching and AI to offer customized career advice, courses, training, and job opportunities.

“There just isn’t enough talent out there. At the same time the learning and development landscape for additive manufacturing is very fragmented. This makes it difficult for individuals and organisations alike to access courses that can help them upskill. i-AMdigital solves both problems through our digital career growth platform,” said CEO and Co-Founder Nick Pearce of Alexander Daniels Global.

“It is an essential tool for the AM industry that will allow talent to grow their career and make an impact in additive manufacturing. It will provide organisations access to a growing and educated talent force to address their hiring needs and a marketplace for learning and development that can help them upskill their existing workforce in the latest technologies.”

AMable Launches Second Open Project Call

The AMable project, which receives funding from the European Union Horizon 2020 research and innovation program, has just launched its second project call for proposals and ideas that can be applied to AM. The project is continuing to look for new ways to innovate on services for mid-caps and SMEs in the EU, and chosen teams will receive support from the AMable unit.

AMable is a Factories of the Future (FoF) project participating in I4MS (ICT for Manufacturing SMEs), and is working to increase adoption of AM technologies through the EU. The project will build a digital model that will provide unbiased access to the best AM knowledge in Europe in an effort to support this adoption.

Express Group Appointed New UK Distributor for Mayku

GoPrint3D, a division of Express Group Ltd, has just been named the new UK distributor for London startup Mayku. The startup created a desktop vacuum casting unit called the FormBox, which is a handy partner for your 3D printer. Once you create a 3D printed mold, you can put it inside the compact FormBox, which is powered by any vacuum cleaner and works with many materials like wax and concrete, to cast a series from it – putting the power of making in your own hands.

PostProcess Technologies Uses Hybrid DECI Duo Solution to Achieve Excellent Surface Finish for 3D Printed Shrouded Impellers

Exacting Surface Finishing of Complex 3D Printed Metal Geometries.

PostProcess Technologies, which expanded its channel partner coverage in North America this spring, is well known for its software and post-printing solutions. With its automated Hybrid DECI Duo solution, PostProcess helps its customers achieve excellent surface finish standards and replicable results for complex metal parts.

Recently, PostProcess demonstrated in a new case study how well its technology can help other companies. The subject was Ingersoll Rand, a $14 billion global industrial manufacturing company that specializes in compressed air technologies. The company uses 3D printing for its shrouded impellers, which improve the performance of a compressor package more than open impellers because there is no clearance between the stationary inlet and the impeller, so no slip losses occur as a result of compression gas recirculating in the space.

The design for shrouded impellers, which rotate 60,000 RPM, has very tight tolerances in order to meet aerodynamic testing. In addition, the blades need excellent surface finishing, and it takes months to build using conventional forms of manufacturing. So Ingersoll’s engineering team, needing to commercialize its shrouded impeller design, turned to 3D printing because of its complete design freedom; the technology also makes it possible to build the part as monolithic, so no welding is required. But, in order for 3D printed parts to meet performance thresholds, they do require outstanding surface finishes.

Ingersoll 3D prints its shrouded impellers out of titanium and nickel alloy, but they unfortunately come off the print bed at an Ra (roughness average) value that doesn’t meet the engineering team’s specifications. The team has tried everything from manual sanding and grinding tools to chemical etching, but the results were inconsistent and did not have the necessary, repeatable quality needed to produce end parts within the required specifications.

The company needed to find a replicable process that would provide them with the necessary surface finish for its shrouded impeller’s complex geometry, in order to, as PostProcess wrote in its case study, “drive a measurable increase in efficiency for its advanced air compressors.”

So, Ingersoll turned to PostProcess in hopes that the company could work with complex metal part geometries, like organic shapes and internal channels, and help achieve repeatable results and excellent surface finish standards for its shrouded impellers.

Automated DECI Duo for Post-Print Support Removal & Surface Finishing.

PostProcess delivered a “transformative outcome” for Ingersoll’s 3D printed titanium and nickel alloy parts, thanks to its patent-pending, automated Hybrid DECI Duo solution. The Hybrid DECI Duo – a single, multi-functioning, data-driven system – promises fast cycle times for even the most complex of parts Designed to optimize production floor space, the system also includes noise reducing features for a low dBa, an LED lighted chamber, and a manual mode for hands-on part finishing when needed.

The system also uses PostProcess’ proprietary AUTOMAT3D software, in order to optimize energy and exclusive chemistry, which includes detergents and suspended solids so the geometries maintain their fine-feature details while still receiving the desired surface finish.

“We have chosen the DECI Duo because of its repeatability, minimal setup, processing times, and cost of ownership. Photochemical machining, extrude honing, and micro polishing or micro machining all yield very good results when applied correctly, however extensive tooling and equipment costs, setup times, and required DOE’s prior to applying the surface finishing method to obtain a repeatable process have made the DECI Duo a better option,” said Ioannis Hatziprokopiou, Mechanical Engineer, New Product Development, Ingersoll Rand Compression Technologies and Services.

“In addition, some of aforementioned finishing techniques unevenly remove material inside the flow path of the impeller, whereas the DECI Duo uniformly treats the entire surface of the flow path. The final geometry of the flow path must remain as unaltered as possible after post-processing of any kind.”

3D printed shrouded impellers were
implemented on the last 3 stages of this 6 stage 6R3MSGEP+4/30 engineered air booster machine.

The PostProcess solution established operating settings that were in line with Ingersoll’s standards using benchmark parts. Then, the DECI Duo was able to consistently finish metal parts that were able to successfully pass exacting aerodynamic tests.

Ingersoll came to PostProcess with a need for high quality and requirements in consistency and repeatability. But, it’s also achieved additional advantages from working with the company, such as cost savings and ease of operation.

In addition, the DECI Duo also produced an average of 70-80% reduction in Ra for parts run for 20 minutes or less.
