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.

“Extreme strength PLA”

Unitless, no test method

“Heat resistant up to 110 °C”

Resistant — but to what load?

“Easy to print on any machine”

On which slicer, which nozzle?
