Crafts prototype

Name:       Crafts  prototype

Category:  Crafts

SIZE:          586mm*235mm*458mm

Finishing:  Polishing

What  kind of prototype aresuitable for SLS processing method  to make?

◆ Precise dimensions are required;

◆High-temperature resistance during functional test are required;

◆Impact-resistance during functional test are required;

The data you need to provide to us if you adopt SLS prototyping processing:

◆First, Please send us 3D drawing with entitydiagram;

◆Second, change the 3d drawing to picture of the suffix STL;

Pay attention: Should change thechord height andangle control of the STL dialog deviation control options to0.0000 duringconversion

before adjusting (coarse)                              after adjusting(smooth)

The advantage of SLA prototype:

◆High precision.

◆There is no limit for the shape and structure of the prototype with need to be processed, even cannot out of the mold products also can be processed out.

◆The surface quality is good and smooth.

SLS prototyping processing principle

    SLS is the abbreviation of selective laser sintering. The selective laser sintering process principle is contour of prototype which need to be processed into each layer, along the CAD path, the laser scan on each layer of PA powder, the illuminated powder melt into solid liquid, layer by layer accumulated to form the outline of the prototype. Then the table cooling after the machine stopped, and the liquid cooled molding.

The difference between SLS and SLA:

◆The material is different, SLS sintering adopt PA powder to process, whereas SLA adopt photosensitive resin.

◆SLS prototype can resist high temperature and impact powder, and the strength is good. ButSLA is easy to deform when the temperature over 60 degree celsius, and the strength is poor ,easy to break.

◆The surface post–processing treatment of SLS is less convenient than SLA ;

CNC Prototype is very good in bothperformance;
