Does a HEPA filter capture ultrafine particles (UFPs). What toxins does 3D printing produce? Why should every 3D printer have both a activated carbon and HEPA filter?
Because some 3D printing filaments are hygroscopic, meaning that they absorb moisture from the air, prolonged exposure to even moderately humid room air causes moisture saturation. After 150 hours in standard conditions, PLA filament may swell up to 40 micrometers before reaching its saturation point. 3D printers rely on tight tolerances and extremely small layer heights. Before the print even gets underway, an increased filament diameter of even 20 – 40 microns, (roughly the width of a human hair) can derail a build before it ever begins.
What’s the easiest and fastest way to clean 3D printed parts with soluble support materials or standard support materials like HIPS and PVA? Here’s how to clean the reaches of 3D printed parts including small geometries, internal cavities, and between build layers so that each part achieves the smoothest possible finish with the least risk of damage caused by handling, scrubbing, or brushing.
Is sterile 3D printing possible? Are 3D printed parts sterile? This comprehensive guide to 3D printing sterile parts provides materials that withstand various sterilization techniques such as autoclaving, heat, ETO, and gamma. Here’s how 3D printing will enhance medical tooling and device manufacturing.
