Objet's previously released 51 digital materials include combinations made from VeroWhitePlus and rubber-like materials, as well as transparent, polypropylene-like, and rubber-like digital materials. Twenty of the 39 new materials have rigid and rubber-like properties for medical applications. The rigid materials come in new shades of gray and offer improved, polypropylene-like toughness. The rubber-like materials have shore scale A values ranging from 40 to 95. These include rigid transparent and rubber-like black materials.
The other 19 new materials are rigid and rubber-like high-temperature materials for medical surgery planning and automotive applications, as well as for seals, applications in high-humidity environments, and flexible tubing for medical devices. The rubber-like materials also come in shore scale A values ranging from 40 to 95, and the rigid materials come in new shades of gray and offer improved resistance to high temperatures.
Objet also announced two material enhancements. One of the enhanced materials, an Objet Rigid Black material named Objet VeroBlackPlus, provides "increased dimensional stability and surface smoothness," the company said in a press release. The second, Objet's High Temperature Material, is now available on all Objet Connex and Objet EdenV 3D Printers, as well as the new Objet30 Pro Desktop 3D Printer (whose release we covered this week). The material, released last year, has "the high thermal functionality of engineering plastics."
"Digital" materials is the new "i" anything, strictly a marketing term. These materials are manipulated by an electro-mechanical device controlled digitally and the shape that it making arose from a digital file.
Semantic argument aside the technology is fascinating and the proliferation of materials that are compatible with these 3-D printing processes can only serve to make the life of the design engineer simpler. Printing a 3-D part is a first step in the evaluation of a design, does it look, fit, etc. as I expected. If so, good, I can make a more functional prototype with more appropriate materials, if not, good, I didn't spend too much money or waste too much time.
I look forward to the growth of this technology, but I won't be calling these 3-D inks "digital materials".
That's my impression, too, Rob. Objet has been quite consistent in its drive to make more materials available for its 3D process, to serve the need for function as well as for form and fit, in prototypes and models.
Hi - some clarity on our Digital Materials: Digital materials are composite materials made of 2 physical cartridge base materials. The two Objet model materials are integrated in specific concentrations and structures to provide the desired mechanical and thermal properties; enables close simulation of the target product materials. Digital Materials are generated on the fly during the printing process using a software algorithm which defines the jetting pattern which results in the composed materials structure. Digital materials do not exist as cartridge-based materials but only in the resulting model or part.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
Design engineers play a big role in selecting both suppliers and materials for their designs. Our most recent Design News Materials Survey says they continue to be highly involved, in some ways even more than the last time we asked to peek inside their cubicles.
Daihatsu is one of the first carmakers to customize car exteriors using 3D printing's mass customization capabilities. Effect Skins -- small exterior bumper and fender panels in different colors and textures -- can be ordered for its Copen convertible.
Several new products in this group of new adhesives, coatings, and sealants are formulated to protect sensitive electronic components, or to seal components of commercial and military aircraft. Others are designed to operate in tough, messy, dirty oil & gas operations, or for rotary applications and motors.
