- The gap
The 3D printing industry runs on marketing claims. we run the tests.
Every spool ships with bold numbers on the box. Almost none ship with the conditions they were measured under. PrintProof Lab closes that gap with independent, comparative testing and transparent reporting — so you can specify a material the way you’d specify a steel.
- Marketing claim
“Extreme strength PLA”
“Heat resistant up to 110 °C”
“Easy to print on any machine”
