3D printing and injection molding go hand in hand at Danish startup AddiFab

Denmark-headquartered manufacturing supplier AddiFab is in search of to alter prototyping by combining additive manufacturing with formative know-how. A novel strategy, the corporate just lately raised over $1.eight million in EU funding, and it has additionally confirmed an ongoing supplies partnership Mitsubishi Chemical.

Exhibiting alongside its esteemed supplies accomplice subsequent month, AddiFab has now confirmed its attendance at 2019’s RAPID + TCT present. In preparation for the occasion, and likely different public appearances all year long, we check out Freeform Injection Molding (FIM) know-how and the way it works.

AddiFab Freeform Injection Molding

FIM know-how is a 3 step course of. It begins with the digital design of a mould, which is then 3D printed by way of vat polymerization. After rinsing and put up curing, the 3D printed mould is injected with a liquid metallic, plastic (or quickly ceramic) materials, and the mould is dissolved in a water resolution, leaving a strong solid half.

For this goal, AddiFab has developed two machines over the previous 5 years: the Add-Line Automated and the Add-Line Handbook. Designed to 3D print and retailer a number of construct platforms, the principle distinction between these two machines is the extent of automation built-in into put up and pre construct, and the variety of objects they’ll produce in a single batch.  For example, the Add-Line Handbook can produce 20 hearing-aid shells or silicone molds; 15 molds for planet gears; and 45 dental crowns in a single batch. The Add-Line Automated, with automated construct aircraft trade, storage, resin provide and construct restoration, is able to working for 48 hours with out interruption producing hundreds of components.

Sidestepping 3D printing’s materials scarcity 

One of many key challenges that AddiFab goals to beat with its FIM know-how is materials availability inside the growing 3D printing business. Lasse Staal, AddiFab co-founder and CEO explains, “Injection molding—with a a lot richer legacy and R&D budgets dwarfing these of the AM business—is churning out tons of of specialised grades for each generic grade that’s being transformed to additive. And the supplies transformed to AM lose out on efficiency, in contrast with their injection-molded twins.”

“”[…] the race for supplies is about to be totally modified by AddiFab.”

Working with Mitsubishi Chemical, AddiFab technicians have been testing particular grades of the Japanese company’s Tefabloc and KyronMax injection moldable supplies.

A kind of excessive efficiency TPE “Tefabloc,” in keeping with Jon Jessen, AddiFab co-founder and chief innovation officer, “might be the easiest-to-mold elastomer we now have ever labored with. The fabric parameters had been extraordinarily straightforward to dial in, and we had been shortly in a position to overmold, in addition to display the geometric complexity that’s potential with Freeform Injection Molding.”

KyronMax on the otherhand are a bunch of renifroced polymers. “KyronMax engineering plastics are among the many best supplies within the Mitsubishi Chemical portfolio for metallic substitute in structural functions,” feedback Jeff Gerbec, Regional Expertise Supervisor at Mitsubishi Chemical America.

“With Freeform Injection Molding, we will obtain excellent materials properties on an additive platform whereas utilizing our present feedstocks. We’re at the moment testing KyronMAX’s high-performance property retention when used with FIM know-how, and the primary outcomes are very promising.”

$1.eight million from Horizon 2020

AddiFab was awarded over $1.eight million in funding to superior its FIM strategy for ceramic and metallic casting in March 2019. The cash for this improvement was supplied by the European Union’s Horizon 2020 program, which additionally supplied €10.6 million to 3D printed electronics improvement on the Danish Technological Institute (DTI) this month.

AddiFab will current its FIM know-how on the 2019 RAPID + TCT present in Detroit subsequent month alongside Mitsubishi Chemical at sales space 2105.

3D Printing Business shall be reporting dwell from RAPID + TCT Might 20 by 23, 2019. To remain updated with all the most recent information and releases from this occasion and extra, subscribe to the 3D Printing Business publication, observe us on Twitter and like us on Fb.
