Working with stereolithographic (SLA) parts
SLA or stereo lithography 3D printing is one of the oldest technologies, and still one of the best and most accurate. For highly intricate parts with lots of details, SLA is a great choice. Most people don't have an SLA machine because they're generally more complex and require liquid resin and other harsh chemicals. You probably won't need to worry about these issues because more than likely you'll be sending your parts out to a service provider. However, Formlabs makes a machine that can produce small parts that is sold for a reasonable price. So understanding the build method will help you choose the best process for your prototype. With that in mind, let's take a look at an SLA part. You can see this part here has got a nice fine build lines, it's got no issues with sag, and we don't have any of the issues we looked at before on the FDM process. Here's a couple parts to compare against. You can see this one is an FDM, here's the SLA, and then here's the PolyJet part. So, you can…
