Metal 3D Printing
Direct Metal Laser Sintering (DMLS) uses a fibre laser system that draws atomized metal powder to the surface and welds the powder into fully dense metal parts.
Stereolithography (SLA)
Stereolithography (SLA) uses an ultraviolet laser to form thousands of thin layers on the surface of a liquid thermoset resin until the final part is formed.
Selective Laser Sintering (SLS)
Selective Laser Sintering (SLS) uses a CO2 laser to fuse nylon-based powders, layer by layer until the final thermoplastic part is built.
Multi Jet Fusion (MJF)
Multi Jet Fusion selectively fuses and refines fusing and refining agents onto a bed of nylon powder and subsequently employs a heater to sinter together the nylon powder to form a solid functional part.
Engineering Support for 3D Printing Projects
We help turn your 3D models into printable, functional, and production-ready parts.
From file checking and material advice to prototype validation and small-batch production, our team provides practical support to reduce printing risks and improve final part quality.
Review STL/STEP files, check wall thickness, small details, hollow structures, assembly gaps, and areas that may fail during printing.
Help select suitable 3D printing technologies and materials based on strength, flexibility, heat resistance, surface finish, accuracy, and application needs.
Support sanding, polishing, painting, dyeing, assembly, and small-batch production to make printed parts ready for testing, display, or end-use.
