These printers are inexpensive resin SLA machines that I have personally used. I do not claim to be an expert in this regard, and proper precautions should always be used when dealing with toxic resins. Relevant video reviews will be in the items description.
Please keep in mind I do not directly sell any of these items. They are all links to purchase the products on Amazon, Matterhackers, and other sources. Some links are affiliate links, which do not add any extra fee to your purchase.
The prices may have changed since this page was edited, since I am not in control of that.
