Sun vs. Machine: The Complete Guide to Curing Your Resin 3D Prints in 2026

You just pulled a print off the build plate. It's shaped right, the detail is there, the supports look clean. You wash it, hold it up to the light, and think:

Does this really need to go in a machine to finish?

The sun is out. The UV index is high. The print is right there in your hand.

The answer — maybe to your surprise — is yes, the sun will absolutely cure it. And in the right circumstances, it'll do it beautifully....

The Resin Safety Guide Nobody Gave You: How to Handle, Store, Recycle, and Dispose of 3D Printing Resin the Right Way

Here is something that the unboxing video didn't tell you.

The bottle of resin sitting on your desk — the one that looks clean and clinical and smells like a chemistry lab — is classified as hazardous waste in most jurisdictions. The liquid that came off your FEP film after that last print, the IPA wash you used to clean the model, the nitrile gloves you peeled off afterward — all of it requires handling that is...

The Best 3D Printer Filament of 2026: Every Material, Every Use Case, One Definitive Guide

Walk into any 3D printing community in 2026 and ask what filament someone uses, and you'll get a different answer from every person in the room.

The PLA devotee who has dialed in their first-layer adhesion to a science. The PETG convert who swears they'll never go back. The ABS veteran who learned to love the smell. The TPU enthusiast who's been printing custom gaskets and phone cases for three years. The nylon and carbon fiber crowd who treat consumer filaments the way...

Breathe Easy: The Best Air Purifiers for 3D Printing in 2026

You can't see it. You can't always smell it. And unless someone told you about it, you probably never thought twice about it.

But right now — if your printer is running — there's something happening in your air. Ultrafine particles smaller than a human red blood cell, released by the melting of filament or the curing of resin. Volatile organic compounds — styrene, formaldehyde, methyl methacrylate — escaping into the room with every layer. A chemical cloud, invisible and odorless (or nearly so), that accumulates over...

The Metal Revolution: How 3D Printing Is Rewriting the Rules of What Metal Can Do

There is a moment in every industrial revolution where the question changes.

It stops being can we do this? — because the answer to that is usually yes, given enough money, enough time, and enough specialized equipment. The real question — the one that separates a laboratory curiosity from a technology that changes the world — is can we do this here, now, by the people who actually need it, at a cost that makes sense?

Metal 3D printing has been answering the...
