Available Finishes for Nexa3D LSPc® Parts
Our default finish. The supported surfaces will be lightly sanded with 220 or 320 grit sandpaper, then media blasted for a uniform matte finish.
Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper for improved surface quality. Sanding scratches will be visible on supported surfaces.
Supported areas may show small grid-like dots or surface blemishes as a result of support removal.
Xometry provides additional finishing options, including but not limited to sanding, polishing, painting, post thermal processing, and plating to meet your needs.

Benefits of LSPc® 3D Printing
Nexa3D’s LSPc 3D printing technology has ultra-fast printing speeds, making it ideal for rapid iterative design and mass production of parts. It supports the printing of various engineering materials, so that the printed parts can withstand the end use environment. LSPc printing has high resolution, good dimensional accuracy and smooth surface, which is very suitable for printing a large number of small parts. At the same time, the simple post-processing and quickly replaceable construction platform can further improve production efficiency.

The tolerance of SLA 3D printing is affected by factors such as stress and support strategies during printing. After the successful printing of the prototype, the tolerances can be further optimized through a manual quotation review, but the specific tolerances need to be evaluated and approved according to the characteristics of each case. Unless otherwise specified, the tolerance data provided refers to the state of the print without post-processing. The specific tolerance control standards for each process can be found in FINDTOP’s manufacturing standards documentation. In short,SLA 3D printing can achieve tolerance control, but it is necessary to consider various factors in the printing process and determine the final tolerance index according to the specific circumstances of each case.
Applications of PolyJet
Nexa3D’s LSPc technology is a mask stereolithography 3D printing process that uses LED light sources and LCD masks to selectively cure photopolymer resins layer by layer to build parts. At its core is the unique Everlast membrane, which greatly reduces the separation force in the printing process and enables ultra-high-speed printing. After printing, the uncured resin needs to be cleaned and UV cured. LSPc supports a wide range of engineered resin materials without complex post-processing and only standard UV curing to achieve final part performance.
