SLA is a technique that often offers a very high precision and an excellent surface finish, but printers are more expensive, as are the consumables, and you have to be very meticulous about preparing your 3D model. On the other hand, the printing quality and most importantly, the precision can be quite different from those offered by the SLA. The DLP is a variant of the SLA that uses a video projector instead of a laser to cure the resin.įDM has the advantage of being permissive on 3D models and the 3D printing process with inexpensive consumables and affordable printers. There are two categories of affordable 3D “desktop” printing techniques: FDM, which consists of melting a plastic wire along a precise path, and SLA, which consists of curing a photosensitive resin by passing a laser beam along an even more precise path. Without going into the details, it is important to understand some techniques and basic 3D printing jargon, especially if you are not an industry specialist. Overview of SLA 3D printing and Formlabs printers This post describes my use of the Form2 for several months. Since then, I have bought my own printer. The Form 2 tested was graciously on loan by Formlabs. That is why I have quickly turned to the Formlabs printer for the SLA and the Ultmaker 2+ Extended for the FDM. Above all, I care for the detail accuracy and the surface finish. I use the printer to print figurines, scanned models and prototype-like models, with a slightly more focus on jewelry, product design and even functional parts.
