the real world is not on the spec sheet...


Unfortunately for engineers, the spec sheet isn’t going to tell you everything you need to know about how a material will perform in the real world. Standardized tests from organizations such as ASTM and ISO are designed to be easy to perform and relevant to a broad range of applications and materials. In this regard, they represent a “lowest common denominator” approach. There purpose is the be “standard”, not to be the best representation of reality.

In this article, we pick a fight with three standardized tests that are ubiquitous in polymer 3D printing...

P.S. - Speaking of real-world testing, we still have some COR Zero bend bars on hand for you to abuse. We are only aware of one person who was able to break it with his bare hands, he is perhaps the strongest man in the world. Others have shared:

  • "Seems like tough stuff. I plan on hitting it with a hammer..."
  • "We were VERY impressed with the bar....it is ASTONISHINGLY strong!!!" (link to post)

Big news from polySpectra! We've teamed up with Tethon 3D to bring you something truly groundbreaking: ThOR 10. You guessed it: Tethon + Cyclic Olefin Resin = ThOR. ThoR is polySpectra's first composite material, designed to compete with glass-filled engineering polymers. Engineers have long been looking for materials that bridge the gap – something stiffer and more heat-resistant than typical photopolymers, but tougher and easier to process than traditional ceramics or metals. Enter ThOR 10:...

You are cordially invited to an exclusive "ask me anything" with polySpectra founder Raymond Weitekamp, this Thursday at 9am Pacific. All things additive manufacturing are fair game, including any final questions you might have about COR Zero before Thursday night's Kickstarter campaign close. Not sure if you can make it? Just reply to this email with your question, and make sure to register so that you receive the recording link. It is election day here in the US, please make sure to get out...

After 4000 days of development, we proudly present: COR Zero! COR Zero is an extremely rugged resin that you can 3D print in your home workshop. We're launching COR Zero today in partnership with Kickstarter. What's new? The ability to print COR Zero at home, using inexpensive equipment: a freezer, a microwave, and a resin 3D printer. What's the same? The best-in-class combination of thermomechanical performance, bio-compatibility, and chemical resistance of polySpectra's Cyclic Olefin...
