Wax 3D Printers — Precision Patterns for Investment Casting
Eliminate wax injection tooling forever. Our SLS wax 3D printers produce intricate patterns directly from CAD — delivering the accuracy, surface finish, and speed that investment casting foundries demand. From industrial turbine blades to automotive components, 3DPTEK wax systems give you pattern-making freedom without the tooling cost.
What Is a Wax 3D Printer?
A wax 3D printer uses Selective Laser Sintering (SLS) to build detailed wax patterns layer by layer from a CAD model. These patterns serve as the master for investment casting (lost-wax casting) — replacing traditional wax injection molds that are expensive, slow to produce, and limited in geometry.
In conventional investment casting, creating a wax pattern requires CNC-machined aluminum injection molds that cost $5,000–$20,000+ and take 4–8 weeks to manufacture. Every design change means a new mold. With SLS wax 3D printing, you skip the mold entirely: the printer builds the wax pattern directly, handling undercuts, thin walls, and internal cavities that are impossible to injection-mold.
3DPTEK wax printers use a CO2 laser to selectively sinter fine wax powder, achieving layer thicknesses as low as 0.08mm and build accuracy of +0.1mm. The resulting patterns have excellent surface finish and ash content below 0.02% — critical for clean burnout in the ceramic shell process.
Why Choose 3DPTEK Wax 3D Printers
Our SLS wax systems are purpose-built for foundries and pattern shops that need speed, precision, and reliability.
High Precision
+-0.1mm accuracy with 0.08mm minimum layer thickness. Print intricate details and complex geometries that traditional wax injection cannot produce.
Fast Iteration
Go from CAD to wax pattern in hours, not weeks. Modify designs and reprint immediately — no tooling changes, no delays.
Zero Tooling Cost
Eliminate $5,000–$20,000+ per injection mold. Every design iteration is free — just change the file and print again.
Foundry-Ready Patterns
PSB wax powder with <0.02% ash content. Patterns burnout cleanly with no residue — compatible with all ceramic shell systems.
How Wax 3D Printing Works
The SLS wax printing process in four simple steps.
CAD Design
Create or import your 3D model. The software slices it into thin layers for the printer.
SLS Printing
A CO2 laser selectively sinters PSB wax powder layer by layer at precise thickness.
Pattern Extraction
Remove the completed wax pattern from the powder bed. No support structures needed.
Investment Casting
Use the pattern as a master for ceramic shell molding, burnout, and metal pouring.

Frequently Asked Questions
A wax 3D printer uses Selective Laser Sintering (SLS) to create detailed wax patterns for investment casting. A CO2 laser selectively melts fine wax powder layer by layer based on a 3D CAD model. The resulting wax pattern replaces traditional wax injection molds, eliminating tooling costs and enabling complex geometries directly from digital designs.
Jewelry manufacturing, aerospace (turbine blades, structural castings), automotive (engine components, transmissions), industrial machinery (pump housings, impellers), and art casting all benefit significantly. Any application requiring investment casting with complex geometries can benefit from SLS wax printing.
The AFS-500 achieves build accuracy of +-0.1mm for parts up to 100mm, and +-0.1% for parts larger than 100mm. Layer thickness can be set between 0.08mm and 0.35mm, giving you excellent control over surface finish and build speed.
Traditional wax injection requires CNC-machined aluminum molds costing $5,000-$20,000+ with 4-8 week lead times. SLS wax 3D printing eliminates the mold entirely: print directly from CAD in hours, change designs instantly, and produce geometries that are impossible to injection-mold (undercuts, internal channels, lattice structures).
