LSPc® stands for Lubricant Sublayer Photo-curing, a proprietary technology developed by Nexa3D. This process provides extremely fast and accurate 3D printing in materials suitable for end-use, making it a viable solution for low volumes to production quantities.
Nexa3D LSPc® Technology In Action
This type of printing technology uses an LED (light-emitting diode) array as a light source and an LCD (liquid crystal diode) photomask to selectively cure layers of photopolymer resin onto a membrane. As each layer is cured, the build platform moves up, the resin is replenished, and the next layer begins to set, building up parts over time. The key to Nexa3D's LSPc technology is their proprietary Everlast membrane which is designed to minimize peel and separation forces during printing. The specialized membrane is chemically inert, flexible, and does not rely on oxygen-permeable elements for lubricity. This enables LSPc technology to print in a wide range of resins with unparalleled speed and efficiency.
What types of materials are available with LSPc®?
A wide selection of materials, including ones that emulate ceramic and rubbers to engineered functional resins for medical, dental, and commercial industries, is available. The resins used with LSPc® typically only require a standard UV-curing and do not require additional treatments such as thermal processing. Xometry's material options include:
- General Purpose
- Prototyping Resins
- Rubber-like Elastomers
- Composite/Filled Resins (e.g., Ceramic-Filled)

What are the tolerances of the Nexa3D LSPc® 3D printing process?
Below you'll find some general tolerances of the LSPc® printing process. For more information, check out our manufacturing standards page.
Tolerance, XY Plane: +/- 0.005” for the first inch is typical, plus +/- 0.002” for every inch thereafter.
Tolerance, Z Plane: +/- 0.010” for the first inch is typical, plus +/- 0.002” for every inch thereafter. Upward-facing surfaces may experience an additional 0.010"-0.020" of growth due to the nature of the required support structures.
Layer Height: 100 µm / 0.004 in
Build Volume: Up to 10.8 x 6.1 x 15.7 in
Minimum Wall Thickness: 0.030" or larger is suggested for any walls, text, or lattice features.
