Liquid Additive Manufacturing Material Launched
Odds are, if you’re going to prototype something, ideally what you’ve made as a one- (or so) off is something that might scale to production.
And it would be particularly good were the material used to produce said model be capable of being ported over to production.
And colors, too
Dow has launched a new two-part platinum-catalyzed, thermoset liquid silicone rubber (LSR), SILASTIC 3D 3335, that can be used in liquid additive manufacturing (LAM) processes, such as that performed by the German RepRap L320 3D printer.
The LSR material is transparent. Which is useful in some applications.
But Dow and German RepRap have been working with an Austrian company, Nexus Elastomer Systems, on a dosing system that allows the use of companion color packs from Mesgo Iride Colors, an Italian company.
(It is worth noting that this Euro-centric tech is being shown at the K 2019 Trade Fair in Düsseldorf.)
And about that transition. . .
According to Dow, “Properties of 3D-printed parts are comparable to injection-molded components” and “Transfers easily to injection-molding processes for high-volume manufacturing.”
Which is the ideal end state for a prototype part.
Ram Truck chief exterior designer Joe Dehner talks about how they’ve developed the all-new pickup. “We’ve been building trucks for over 100 years,” he says. “Best I could come up with is that this is our 15th-generation truck.”
Topology optimization cuts part development time and costs, material consumption, and product weight. And it works with additive, subtractive, and all other types of manufacturing processes, too.
Automotive manufacturers are meeting CAFE fuel-efficiency standards through lightweighting, which requires simulation software for design engineers.
