3D Printing Air Quality Roundup

The data from research papers presented here add to a growing foundation of understanding 3D printing safety.

Resin vs Filament: Strength, Quality & Cost

Filament is ideal for trinkets, rapid prototyping, and large prints. Resin is ideal for miniatures, jewelry and high-temperature parts.

Resin Printer Ventilation

The recommended location for a resin printer is a garage or workshop. Resin printers indoors should be enclosed and vented out a window.

Resin Printing Respirator

Respirators are a must-have when interacting with resin and thankfully 3M has affordable facepieces and cartridges.

Cleaning Resin Prints with IPA in an Ultrasonic Cleaner

Ultrasonic Cleaning Prints with IPA

Isopropyl Alcohol (IPA) can be safely used in an ultrasonic cleaner if it is placed in a bag or container with the print.

Recycling Resin Saturated IPA with Distillation

Recycling Resin IPA via Distillation

Distillation results in crystal clear IPA, but there are safety concerns that should be addressed. Filtration alone does not purify IPA.
