SLA is famous for building parts that are cosmetically superior to FDM due to the laser technology capable of printing down to 25 micron layers. Taking part size into account helps to accurately determine how long the part will print. Compared to FDM, the speed is almost negligible.

Unfortunately, no matter how tempting it is to leave a 3D printer on overnight or unattended, it can create risks. Most manufacturers strongly advise against doing so. While there are some management and risk-reduction steps you can take, leaving a 3D printer on overnight always creates risk.

3D printers can run 24/7 successfully as shown by many print farms around the world. Printers that run constantly do have failures from time to time, but generally speaking, they can run for several hours concurrently without issues. Some single large 3D prints can run for over 2 weeks.

To avoid over-curing, check the state of your resin model frequently. If it is under-cured, you can simply put it back under UV light. Because UV rays from the sun also gradually cure and degrade photopolymer resins, keeping your 3D printed object in the sun can also cause over-curing over time.

When you don't cure resin prints, they remain soft, leaving them in a fragile state. They won't be suitable for painting, either. You should always cure your resin prints if you want your work to last. Doing so makes them stronger and more stable.

If the shelf life of resin has expired, do not fear. You may still be able to use it for your projects. If you've stored it properly, it should cure, but may have an amber color. If you are coloring the resin, this will unlikely be noticeable.

How Long Does 500ml of Resin Last? 500ml of resin can last the average user around 2 weeks of normal use when printing small models on a regular basis. You could use 500ml of resin in a few really large 3D prints, which could take 2 or 3 days. 1 liter of resin can last you anywhere from 5 days to a month of printing.

3D printing resin can go bad, deteriorating output quality. In most cases, 3D printing resins expire within 12 months. However, sunlight, heat, and chemical contaminants may make them unusable within days or weeks. Read on for more insights into the shelf life of 3D printing resin.

Is resin more expensive than filament? While resin prints are more detailed in general, the cost of purchasing resin compared to filament is higher, and can often be over double the cost of filament per print.

2. Next, submerge your print in a container of Isopropyl Alcohol (IPA) for 3 minutes. Then, swirl it around in the IPA to rinse off extra resin. Alternatively, you can use a squeeze bottle to rinse off extra resin.
