WHAT IS SLA AND SLS?
Light curing process, also referred to as SL is called a stereolithography rapid prototyping process belongs to, also sometimes referred to as SLA. the process is a RP process developed in 1986 in the United States, 1987 by the United States patent, is the earliest and most mature technology and application of rapid prototyping technology is the most widely. With photosensitive resin as raw material, through the computer control of ultraviolet laser stone layer solidification. This method is simple, automatic manufacturing of surface quality and size precision, complex geometry of the prototype.
Sintering, referred to as SLS, using infrared laser to powder material (nylon, nylon fiber, nylon fiber, nylon powder, PS materials and various metal materials include: die steel, titanium alloy, Aluminum Alloy and CoCrMo alloy, nickel iron alloy etc.) directly sintering. EOS EOSINT M280, representative: P395, is a leading global metal forming and plastic molding equipment.
SLA & SLS PROTOTYPING
SLA and SLS services allow you to make 3D printed parts and prototypes in a range of plastics. Prototypes made using this service can be used for engineering testing or as master models for polyurethane vacuum casting molds. SLA and SLS both allow the product designer to quickly create complex shapes that cannot be made with conventional subtractive methods. You can also have metal 3D printed parts made using our DMLM service.
ADVANTAGES OF SLA AND SLS
There are advantages and disadvantages to both techniques that should be considered carefully to achieve the desired results.
SLA produces a part with：
1.A good, smooth surface finish and fine resolution
2.Better surface quality
3.Forming precision is high, the precision is about 0.1mm
4.System resolution is higher
SLA produces a part with：
1.Can use a variety of materials
2.Manufacturing process is relatively simple
4.No need to support the structure
5.The material utilization rate is high
6.Short production cycle, which makes it particularly suitable for the development of new products
7.Combined with the traditional process, it can realize the function of rapid casting, rapid tooling, small batch output, etc
SLA&SLS are suitable for the production of small parts, can be directly obtained resin or similar engineering plastic products. The conceptual model is mainly used for prototyping, or to do a simple test and assembly process planning.
Product design certification, high-precision molds, injection molding die shaped hot runner rapid production.
Direct manufacturing of precision metal parts, model demonstration test, direct manufacturing of fire protection parts, fixture, etc.
Human implants, teeth, skull repair, prosthetics, medical equipment research and development.
The new product development, prototype verification.
Creative design and display in the fields of culture, creativity, clothing, household goods and so on
THE ADVANTAGE OF ALL 3D PRINTING PROCESSES IS THAT IS EASIER TO CREATE COMPLEX PIECES THAT ARE PHYSICALLY IMPOSSIBLE TO MAKE WITH CONVENTIONAL OR SUBTRACTIVE MANUFACTURING.
We offer both SLA and SLS prototyping to create solid physical models in ABS, nylon and other grades of engineering plastic.
SLA and SLS models typically have layer thicknesses of .3mm with a lateral deviation of .1mm. Finer tolerances than this can easily be achieved with post machining per customer requirements. See our tolerance guide for information about our capabilities and plastic materials available.
