Pieces modeled by computer and made with FDM (Fused Deposition Modeling) 3D printers that use PLA (polylactic acid) can be implemented in the procedures ofartistic casting. However, models printed by PLA are limited to approximate minimum sizes of 3 cm,and the optimal layer height resolution is 0.1 mm. These sizes and resolutions are not suitable forcreating microsculptures used, in many cases, in jewelry. An alternative to solve this limitation, is touse a DMLS (Direct Metal Laser Sintering) 3D printer. However, due to its high cost, it is a technologythat is difficult to introduce in small artistic foundries. This work detailed the design and validationof a DLP (Digital Light Processing) 3D printer, using backlit LCD (Liquid Crystal Display) screenswith ultraviolet light. Its development is totally “open source” and is proposed as a kit made up ofelectronic components, based on Arduino and easy to access mechanical components in the market.Most parts can be manufactured in low cost FDM (Fused Deposition Modeling) 3D printers. Theresult is an affordable, high resolution (0.021 mm), and open-design printer that can be implementedin artistic contexts.
