China Rapid Prototyping: SLA or SLS, How to Choose?

 
3D printing is a revolutionary technology. This method directly uses the product’s three-dimensional computer data to achieve a prototype of the product based on the principle of layer-by-layer stacking of discrete layers. SLA and SLS are two mature laser China Rapid Prototyping technologies, and the material used in SLA is mainly photosensitive resin. At Vowin Rapid, we offer SLA and SLS prototype in a variety of plastic materials.


 
SLA.Rapid PrototypingThe advantages of SLA
- High-precision prototyping with a tolerance within 0.1mm.
- Smooth surface leads to less post polishing.
- Can print product with thin-walled structures.
- A short processing cycle usually only takes around 3 days for completion.
 
The Defects of SLA
- Limited alternative materials as it requires the use of photosensitive resin.
- The processing material is relatively weak and cannot bear times of disassembling and screwing.
 


SLS,Rapid PrototypingThe Advantages of SLS
- Multiple materials can be used with a high rate of utilization and wide application scope.
- A short production cycle usually only takes around 3 days for completion.
 
The Defects of SLS
- Surface finish quality is relatively poor compared to SLA.
- The precision is lower than SLA in the production of small or high-precise product
