We toured several 3D Printer factories, including Prusa Research, Printed Solid, Printerior, and ProtoPasta, to learn how 3D Printing filament is made.

The filament is sold in spools by the various 3D printer manufacturers and specialty vendors–it comes in a multitude of colors and textures, including coffee-based.

Toybox sells standard half-pound spools of PLA in a variety of colors for $10 each, and specialty filaments such as gloss and sparkle varieties for $14 a spool.

We break down the pros and cons of the various types of 3D printing materials, from PETG to TPU, to help you figure out which filament is best for your prints.

In this installment, Charles tells us why using high-quality filament is one of the most important parameters in achieving good results.

In another and similar effort to make filament-based 3D printing more green, Purdue University students recently created a soy-based recyclable filament for 3D printing — and have the top prize ...
