4 Reasons to Make Taurus Your New Automotive Prototyping Material
#1 Great surface quality means great first impressions.
Straight out of the machine, Taurus parts are a charcoal black color with a strikingly smooth, glossy surface. “When I saw our first test builds in Taurus come off the platform, I was really impressed. It just doesn’t look like your average Stereolithography material,” says Jonas. “If you need to pitch a concept with a prototype in your hands, you start off on a much stronger footing when you know your prototype looks good. First impressions are everything, even at the prototype stage.”
#2 Post-production? Not necessary.
For the above reasons, the automotive industry is already used to ordering rapid prototypes in darker colors. But unlike other materials, using Taurus for automotive prototypes means you don’t need to apply paint in post-production. In fact, if you like the black look, Jonas recommends that you keep the post-production finishing to a minimum.
“Unfinished Taurus parts are glossy and nearly black, but sandblasting causes the surface to become matte gray. So if you need a black prototype without spending time and money on post-production painting, you just need to pick Taurus with our Basic finish.”

#3 High elongation at break means it’s better for prototyping snap-fit mechanisms.
Combined with the dimensional accuracy of our Stereolithography machines, Taurus is perfect for not just visual prototypes but also for your form-and-fit tests. In our Taurus bull sample, in the video above, did you notice the flexibility of the horns? An elongation at break that high is uncommon in Stereolithography materials. “To take full advantage of this property in Taurus, try a slightly lower wall thickness in the zones where you need to achieve flexibility,” advises Jonas. “But don’t push it below the minimum recommended, or you’ll risk warpage.”
For automotive parts, Taurus’s high elongation at break (combined with SLA lead times) means the opportunity to start form-and-fit tests early in your design stage. Try Taurus to prototype snap-fit mechanisms, where you need to combine flexibility and strength, or gap-and-flush inspections.
#4 Low porosity, perfect for flow testing prototypes.
Like all Stereolithography materials, Taurus is water-resistant and non-porous. That makes it a great choice for prototypes needed for flow analysis and testing. “Powder-based 3D printing plastics are great when it comes to functionality, but they always need sealing before you can use them for applications like flow testing,” says Jonas. “With SLA materials, you can skip that post-production sealing step and head straight into flow testing.”
