3D Printer Resin

Filter

3D printer resin is a liquid photopolymer that cures when exposed to ultraviolet (UV) light. A resin 3D printer consists of four basic components: a tank of photopolymer resin, a transparent window housing, a ... display technology and a UV light source.

HATCHBOX 3D printer resin works best with the two most common display technologies, LCD and DLP. Whether you have an LCD printer or a DLP printer, they work in much the same way by passing a UV image of each layer through the window into the 3D resin. With that layer cured, the print bed moves up, and liquid resin flows across the window to create the next layer.

Resin 3D printers offer several advantages over filament printers:
• Fine details
• Smooth surface finishes
• Truly solid, water-tight objects
• Orientation does not affect strength
• Fast print runs

Since photopolymer resins are toxic, they require learning new workflows and safety procedures. Personal protective equipment and well-ventilated workspaces are critical. You must carefully clean the printed object inside and out to prevent exposure to leftover resin using isopropyl alcohol. And you will need to expose the object to UV light for several minutes or hours to finish the curing process.

When fit and finish matter most, a resin 3D printer may be your best choice. Engineers leverage UV 3D printing’s advantages to create dimensionally accurate prototypes. Hobbyists use 3D resin to create miniatures and jewelry. However, cured photopolymer resins are brittle so they are unsuitable for load-bearing applications.
