The last step in post-processing is to UV-cure your print. This is necessary for many functional resins because it finalizes the material properties of the model.
Method #1: Curing Station
Many SLA printer manufacturers also sell curing stations. These are specifically optimized for their resins, allowing for finely tuned curing times. This is useful for larger prints and professional environments.
Method #2: Nail Polish Curing Lamp
This is an inexpensive and accessible method of quickly curing your model. Simply place it under a nail polish lamp and let it sit overnight. Adding a turntable can help get a more even exposure.
Method #3: DIY Curing Chamber
Many hobbyists will build their own, inexpensive curing chambers, makeshift versions of commercial curing stations. This is easily done by placing a UV light in a box lined with aluminum foil. Place the model on a solar or battery powered turntable to get an even exposure.
Method #3: Solar Power
To go fully green, use good-old solar power. Place your part outside on a sunny day, and you’ll have a nice, even, UV light. The main drawback of this approach is the extra patience required. You’ll have to sit back and let the sun do the work.
