How ti works
How it works: 1. Data is sliced into thin layers 2.Data then transfer to an SLA additive manufacturing which contain a UV-curable photopolymer. 3. Machines begins to build the part one layer and each layer is constructed from a ultraviolet laser 4. The laser trace the cross-section on the surface of the resin and liquid material hard the contract. 5. A recoater blade moves across the surface;the laser continue to trace. 6. remove the complete part from liquid and separated from a platform.Remove support material.
Step 1: Obtain an instant quote using online SLA calculater
Step 2: Order can be placed via email or phone.
Step 3: Prepare CAD data and sent to SLA machine.
Step 4: The laser start to build process.
Step 5: Complete laser building process.
Step 6: remove resin structure support.
Step 7: Clean part goes into a UV oven for curing.
Step 8: Ready finishing and assembly.
Different parts in SLA machine
Vat: filled with photo-polymerizable liquid resin.
Platform: lower subsequently into the vat and the part is build layer by layer.
Laser beam: ultraviolet beam;trace a cross-section of the part pattern.
Servomotors: drive a set of mirrors that reflect the laser beam to the surface of the polymer materials.
Selective Laser Sintering
a process which use laser selectively to trace the surface of powder and sinters the materials together.
The process: 1. split CAD data into thin cross-section.2. data transfer to SLS equipment. 3. the laser scan the surface, material is heated and fused together. 4. powder bed is lowered to make room for next layer. 5. repeated step until the part is complete.
Three area of the equipment.
Control area: Slice the parts; control the entire building process.
Atmosphere control unit:
Fused deposition modeling
The process: 1. slicing cad date into layers. 2. data transfer to machine. 3. Support materials are used to create each cross-section of the part. 4.Build platform move down, building the part layer by layer. 5. Remove the finish part from from build platform and clean support material.
