Like FDM printers SLA devices are also additive manufacturing machines they build up an object layer by layer rather than removing parts of material like CNC machines do. Moving a heavy print head around very quickly will introduce vibrations which become visible in the printed object as unwanted surface structures. Since FDM printers have many moving parts the print quality is hugely affected by the mechanics of the printer. Since only one strand at a time can be placed this process is rather slow and print time is related to complexity of the object and the size of the nozzle. The printer moves the nozzle around in a 3D coordinate space to build up the 3D printed object. Fused Deposition Modeling printers melt a strand of thermoplastics and squeeze the plastic out of a thin nozzle. My Tevo Tarantula for instance is capable of very good prints and is available for around USD $200. Thank you! 3D Printer Technologies FDMĮver since in 2009 the patents for the FDM printing process expired the costs came quickly down from USD 10’000 for a machine to less than $1000 or even less.

No money has changed hands for this review. In this article I will introduce you to SLA printing in general and share my thoughts about the Anet N4 SLA printer.įull disclosure: I have received the Anet N4 printer free of charge from Gearbest to write a review. I’ve been given the chance to test such an entry level SLA printer. These devices can produce prints with very different properties compared to the well know Fused Deposition Modeling printers (FDM).
Recently a new class of 3D printers has become affordable for hobbyists: several Stereo Lithography (SLA) printers are now available for prices below USD $600.
