3D Printing Process

SLS 3D printing

SLS (Selective Laser Sintering) printing fuse the powder (typically nylon powder) to form the part by laser technology. Without additional supporting materials, the SLS printed parts allow high flexibility and are very suitable for functional parts and moving parts from prototypes. Parts can be assembled or jointed.

Step 1: The powder to be spread in a thin and dense layer on top of a platform.
Step 2: The platform to be heated below the melting temperature to make it easier for fusing.
Step 3: A laser selectively scans the powder and sinters them according to the cross-section contour of the layer.
Step 4: A Powder spreader such as a blade or roller creates a thin and uniform layer for the next layer fusing.
Step 5: This process is repeated until all layers are sintered.
Step 6: Remove and clean the loose powder to get the part after the printing process.

SLA 3D printing

SLA (Stereo lithography Appearance) printing is applicable to presentation prototypes, concept models, and translucent prototypes. To create parts, the process cures the photopolymer layer by layer by UV light. SLA technology becomes popular because of the result of high resolution.

Step 1: The UV laser beam scans the cross-section of the part by the reflection of the lens.
Step 2: The scanned liquid material is hardened to be a single layer.
Step 3: The building platform is indexed down and the recoater blade slides to create a new layer.
Step 4: This process is repeated until all layers are hardened.
Step 5: Clean the additional resin and complete the final cure.

SLM 3D printing

 We use SLM (Selective Laser Melting) to print metal parts. The metal powder will be melted and formed layer by layer to build the part. 3D printing manufacturing reduces material waste and enhances the flexibility of the design. That’s why metal printing to be a popular alternative to machining services.

The process of SLM is similar to SLS. The heating temperature from the SLS laser beam is lower than the powder melting temperature. But for SLM, the laser beam melts the metal powder, which makes the printed metal parts to have similar physical and mechanical properties as conventional metal parts. SLM can be used to create realistic metal prototypes or small batch series of metal parts.
