As the industry grows faster and faster, 3D printing has become a favorite of many engineers and customers in rapid prototype industry and the design industry because of its convenience and low cost.
We often receive many customers’ questions, what is the difference between SLA and SLS in 3D printing?
In order to let more customers know more information, we try to explanation as the following hopefully it can help someone in one day .
SLA (Stereo lithography Apparatus) technology also known as light modeling, stereolithography and three-dimensional printing, the process is based on the liquid photosensitive resin filled the tank, controlled by a computer laser track layered cross-section trajectory, and shine in the tank Of the liquid resin, leaving this layer of resin curing, after which the lifting platform is lowered by a layer of height, the formed layer is covered with a layer of resin, and then a new layer of scanning, a layer of new curing firmly stuck The previous level, so repeat until the entire part is manufactured, get a three-dimensional solid model
SLS (Selective Laser Sintering) process is: first on the table covered with a layer of powder, under the control of a computer with a laser beam selective sintering (part of the hollow part is not sintered, is still a powder material), the sintered part It solidifies together to form a solid part of the part. After the completion of a layer of the next layer, the new layer and its layer is firmly sintered together. After all the sintering is completed, the excess powder is removed to obtain sintered parts.
The difference between SLA processing and SLS processing:
- The comparison of some parameters of the two laser printing technologies is as follows:
2.SLA and SLS technology in the laser light source on the big difference:3.General SLS laser sintering using higher energy laser, and SLA generally use UV laser, the use of energy does not need too high.
4SLA and SLS also have the difference in raw materials:
SLS laser sintering is suitable for most fusible materials such as PA, PA + GF, and the printing material is in powder form. SLA laser curing is suitable for photocurable materials and the printing material is liquid.
We are not limited to 3D printing, we also good at CNC precision machining, machining, precision sheet metal custom, whether it is a small batch or volume, we can customize the most reasonable for your production program , You can do a variety of surface treatment you want from processing to surface treatment through-train service welcome to contact us!
