3D Printing Materials
All 3D printed parts are not made equal, and if the clothes make the man, then the material makes the 3D printed part. When 3D printing an object, choosing the correct material for the application is just as critical as choosing the best printing technology. For example, PLA is a great material for figurines because it isn’t prone to warping, but it would make a terrible shock absorber as it’s quite brittle.
This guide gives you an insight in the most used 3D printing materials. For each material, we’ve listed the properties, applications and their corresponding technologies.
Polymer
From realistic display models to functional prototypes, tooling and end-use parts, the opportunities created by polymer 3D printing are immense. Did you know that some high-performance thermoplastics are even tougher than aluminum?
