Surface Finishes for SLA

SLA (Stereolithography) 3D printing delivers high-resolution parts—these top surface finishes elevate their look, feel, and performance for functional and visual applications.

As-Printed Finish
Manual sanding of 3D printed part to smooth surface and remove print layer lines

Naturally smooth with fine detail, ideal for prototypes where high resolution is key.

Sanding & Polishing
Surface Finishes for SLA Sanding & Polishing

Removes support marks and layer lines, resulting in a glossy or matte finish depending on the level of polish.

Painting
CNC grinding process with coolant and sparks for precision metal part finishing

Adds vibrant colour and surface protection—great for display models or consumer-ready prototypes.

Clear Coating
Applying clear coating with brush to enhance finish of SLA 3D printed part

Enhances transparency in clear resins and seals the surface against moisture and wear.

UV Curing

SLA 3D Printing Process at XC Machining

At XC Machining, we utilize advanced SLA 3D printers equipped with the latest laser technology to produce parts with exceptional accuracy and surface finish. The process involves several stages to ensure the highest quality results for our clients:

Design and File Preparation
The process begins with the creation of a 3D model, typically using CAD (Computer-Aided Design) software. The model is then converted into an STL (Stereolithography) file, which contains the data necessary for 3D printing. This file is sliced into thin layers that guide the laser during the printing process.

Material Selection
SLA printing uses photopolymer resin as the primary material, and there are various types of resins available to suit different applications. These materials can have properties ranging from high strength and rigidity to flexibility and durability.

Printing the Part
The SLA printer uses an ultraviolet (UV) laser to selectively cure the resin in the shape of the first layer. As the laser moves across the resin, it solidifies the material in the desired pattern. The process repeats for each successive layer, building up the part layer by layer. This layer-by-layer approach is what enables SLA printing to achieve such high precision and fine details.

Post-Processing
Once the part is printed, it must undergo post-processing to remove excess resin and ensure the final product is ready for use. This involves cleaning the part in a bath of isopropyl alcohol (IPA) to remove any uncured resin. Other post-processing steps can include sanding, painting, and polishing to achieve the desired surface finish.
