Introduction to LSPc (Lubricant Sublayer Photo-curing)

Lubricant Sublayer Photo-curing (LSPc) is a groundbreaking 3D printing technology that has been gaining attention in the additive manufacturing industry. It’s a process that involves the use of a lubricant layer to facilitate rapid photo-curing of materials. This article aims to provide a comprehensive understanding of LSPc, comparing it with various other 3D printing technologies such as Vat Photopolymerization (VPP), Masked Stereolithography (MSLA), Digital Light Synthesis (DLS), Direct Light Projection (DLP), Stereolithography (SLA), Lithography-based Ceramic Manufacturing (LCM), Continuous Digital Light Manufacturing (cDLM), Hybrid PhotoSynthesis (HPS), Lithography-based Metal Manufacturing (LMM), and Two Photon Polymerization (2PP).

Understanding LSPc Technology

LSPc technology, developed by Nexa3D, represents a significant advancement in the field of 3D printing. The key feature of LSPc is its use of a lubricant sublayer that allows for faster and more efficient curing of photopolymers. This results in a faster printing process without compromising on the quality and detail of the final product.

How LSPc Works

The process starts with a thin layer of lubricant spread over the build platform. The photopolymer resin is then applied over this lubricant layer. When exposed to light, the resin cures and solidifies rapidly, forming the desired shape. The lubricant layer plays a crucial role in ensuring a smooth, quick, and precise curing process.

Comparisons with Other 3D Printing Technologies

LSPc vs. VPP (Vat Photopolymerization)

Vat Photopolymerization is a broad category of 3D printing technologies that includes SLA, DLP, and cDLM. LSPc differs from traditional VPP in its use of the lubricant layer, which significantly speeds up the printing process. While VPP technologies offer high precision, LSPc combines speed with precision, making it a more efficient option for rapid prototyping and production.

LSPc and MSLA (Masked Stereolithography)

MSLA uses an LCD screen to mask the image of each layer, curing the entire layer in one go. While MSLA is faster than traditional SLA, LSPc still outpaces it in terms of overall speed due to the lubricant layer’s efficiency in facilitating rapid curing.

LSPc vs. DLS (Digital Light Synthesis)

Digital Light Synthesis, developed by Carbon, uses a similar approach to VPP but with continuous liquid interface production (CLIP). LSPc, however, still holds an advantage in speed due to its unique lubricant sublayer, making it ideal for high-volume production.

Comparing LSPc with DLP (Direct Light Projection) and SLA (Stereolithography)

Both DLP and SLA are forms of VPP. DLP uses a digital projector screen to flash a single image of each layer all at once, while SLA uses a laser to draw each layer. LSPc’s main advantage over these technologies lies in its rapid production capabilities.

LSPc in Relation to LCM, cDLM, HPS, LMM, and 2PP

LSPc’s comparison with these technologies further highlights its efficiency. LCM, cDLM, HPS, LMM, and 2PP each have unique features suited for specific applications, but LSPc stands out for its speed, making it a versatile choice for various applications.

Applications and Advantages of LSPc

Key Benefits of LSPc

  • Speed: The lubricant layer significantly reduces the time taken for each layer to cure.
  • Precision: Despite its speed, LSPc does not compromise on the detail and accuracy of the prints.
  • Flexibility: Suitable for a wide range of materials and applications.


LSPc finds applications in rapid prototyping, dental, automotive, and aerospace industries, among others, where speed and precision are crucial.

Future of LSPc in Additive Manufacturing

The future of LSPc looks promising, with its potential to revolutionize the speed of 3D printing while maintaining high quality. As the technology matures, we can expect broader adoption across various industries, further solidifying its place in the additive manufacturing landscape.


LSPc represents a significant leap in 3D printing technology, offering unparalleled speed without sacrificing precision or quality. Its comparison with other technologies like VPP, MSLA, DLS, DLP, SLA, LCM, cDLM, HPS, LMM, and 2PP highlights its unique advantages, particularly in terms of production speed. As additive manufacturing continues to evolve, LSPc is poised to play a key role in shaping the future of rapid prototyping and production.
