SLS Process

1. Design Specification

Respective account manager will convert the 3D drawing file provided by customer to STL file format and examine if the file meets the standard requirements such as size, structure, thickness of parts and other elements. To check if there are problems with the file, and make quick diagnosis and rectification. Then, make a confirmation about materials, technics and finishing process with customer. (Software includes Rhino 6, Magics 20.03 64bit)

2. Order Confirmation

Confirm with customers regarding resin materials, delivery time, quantity, invoices, receipts, information of the consignee, special requirements and other details hence order can be placed quickly.

2. Order Confirmation

3. Review

Our expert team will check if the file meets the printing standard (minimum thickness, size, and depth of the aperture).

4. Programming and Typesetting

It is a process to determine the part placement mode. SLS printing does not need support structures. The printing effect depends on the part placement and position of constructions. Since the printing effect inclined according to the structure and height, hence the printing layout should incline 45 degree. Material will be placed in build chamber and building parts layer-by-layer until parts complete.

5. Printing

Setup: Upload files to the system and start printing.

5. Printing

Offload: Offload, cool down and unpack building construction. (Dismantle the build chamber and recycle the remaining powder from the work piece, this process will takes about 5-6 hours)

6. Post-processing

Sandblasting: The main purpose of sandblasting is to remove the powder material from the surface of the part. The unwrapped part placed in the sandblasting machine. The high-speed air flow ejected from the air compressor which impinges on the surface of the product to take away the excess powder and make the surface smooth.

Dyeing: After sandblasting, dyeing equipment will be heated, disseminated and cooled. The dyeing temperature is about 120°C.

Drying: Place the construction in the oven and dry for 40 minutes.

7. Inspection

7. Inspection

Initial checking: Clear powder, hole dredging.

Quality checking: The quality inspector checks the size, quantity, and dyeing effect of the part according to the drawings.

8. Inspection, Packaging and Delivery

Finished product will be wrapped carefully for deliver to customer. We will cover the part with foam ball to ensure the part will not damage during transportation. We will pay extra attention to sensitive part.

8. Inspection, Packaging and Delivery

9. Order-Tracking

Each process will be updated on website after completion which enable to follow the production process on time.
