About 3D Printer Resins
What is resin 3D Printing?
Resin 3D printing, or SLA 3D Printing, is the process by which liquid resins are cured or hardened layer-by-layer using a laser (laser SLA), LCD screen (MSLA), or digital light projector (DLP).
SLA 3D printers are capable of incredibly detailed 3D prints at a high resolution without the easily visible layer lines typically associated with FDM 3D printing. Once an SLA printed part is complete, it must be post-processed in UV light.
The high precision of SLA 3D printed parts makes resin a popular option for printing small, finely detailed models such as dental models, medical models, jewelry and even miniatures.
What kind of resins are used for 3D Printing?
There are many different resin materials that provide high-quality and highly detailed, smooth results when compared to FDM 3D printers and filament. Explore a wide variety of properties between differing resins such as:
- High-Temperature 3D Printer Resins - High-temperature resins for stronger, bolder 3D printed parts
- Flexible 3D Printer Resins - Flexible Resins that can bend but also maintain their shape
- Casting 3D Printer Resins - Rapid prototype castable products using lost wax and metal casting.
- PRO Series Epoxy-Free Resins - MatterHackers PRO Series Resin combines the industry-leading features of epoxy-free and incredibly stable 3D Printer Photopolymer Resin with application-specific formulas like High Precision, Dental Model, and more.
Is 3D Printer resin expensive?
No, 3D printer resin is not expensive. You can find 3D Printer resin for as low as $18.98 per 500g bag, like our MH Build Series Resin.
What considerations should I be aware of with SLA 3D Printing?
Unlike the plastics used in FFF 3D printing, the resins used in SLA 3D printing are not inert and are actually a skin-irritant in their uncured form that require some precautions in order to use safely. Most importantly, be sure to wear nitrile gloves anytime you intend to handle liquid resins.

Is resin stronger than PLA?
As with FFF, plastic 3D printing, you want to choose the right medium and material to best suit the project you are working on because in some cases the strength a resin 3D print provides might be enough to work, and in others you might need an FFF 3D print to save the day.

Can I leave my 3D printer on overnight?
Yes. Depending on the height of your models and whether you are using a 3D printer that cures resin in layers (MSLA and DLP) or along a toolpath (SLA), you may often find yourself with 3D prints that will take longer than 24 hours. There is no need to split up your models to take less time, simply let the 3D print run.
