Stereolithography (SLA) is the oldest form of 3D printing. It works by exposing a layer of photosensitive liquid resin to a UV-laser beam; the resin then hardens in the desired pattern, and the object is built layer by layer until it is complete. This allows you to print a model with extremely fine detail.
Can you use resin in a 3D printer?
A resin 3D printer is a machine which uses wavelengths of UV light from an LCD to cure and harden photosensitive liquid resin from a resin vat below onto a build plate above in small layers. There are a few types of resin 3D printers such as DLP, SLA, and the more popular MSLA machine.
Why is 3D printing resin toxic?
They can create contact dermatitis, which is a surface rash that could develop into an allergy if you expose yourself to resin for long periods of time. Resins also naturally give off fumes, and unless you work in a well-ventilated area, molecules from the fumes will get into your lungs and cause irritation there, too.
How long does resin last 3D printer?
In most cases, 3D printing resins expire within 12 months. However, sunlight, heat, and chemical contaminants may make them unusable within days or weeks.
Can I reuse leftover resin?
If you find yourself with leftover 3D resin after a print, you should save and reuse as much of it by storing it in a cool place away from sunlight. However, any resin you intend to throw away must be dried and cured before disposal to ensure it remains non-toxic.
How do you cure resin in 3D printing?
Submerge the print in a clear container filled with tap water. Then place the container under direct sunlight for about 15 minutes. If the print still feels uncured or sticky, leave the print and the container in the sun for a few more minutes.
What is the difference between a 3D printer and a resin 3D printer?
When considering which of these types of 3D printers to purchase, you’ll first need to think about what types of objects you are planning to make. Filament printers are superior for producing strong, larger parts, while resin printers excel at producing fine details and can print much more precisely on small parts.
