What is SLA Printing?
Stereolithography also commonly known as SLA Printing is one of the most popular and accurate printing methods. It can be used to create simple concept models or complicated specific parts. The process can be completed in a few hours making it a time efficient process.
How is SLA Printing done?
SLA printing uses a resin tank which is filled to a certain level within the printer. A UV laser beam is then scanned throughout the resin turning anywhere it touches into a solid. This process slowly builds up the full 3D model hardening the plastic. When the printout is completed it is washed in rubbing alcohol to remove the excess resin. Any supports created in the printing process will also be removed at this point.
Benefits of SLA Printing
- Full scale models can be printed and processed very quickly
- Models can be cosmetically changed eg, with sanding and painting
- Intricate details can be displayed making it ideal for visual concepts and models
- Durable material
- Large build bed size for efficient printing
SLA Printing at London 3D Printing
At London 3D printing we use large format machines, providing a higher quality final product than other market competitors. By providing us with your animated model we will be able to discuss a competitive build time and pricing suitable for your project. We have previously worked on projects including Star Wars, Guardians of the Galaxy, Lord of the Rings and many more. We regularly deliver to film studios local to our Uxbridge workshop.
Selective Laser Sintering SLS 3D Printing
SLS utilises thermoplastic polymers in a fusion bed process. It is a great option for printing small to medium size prototypes. This is because SLS parts are formed from nylon powder making them both strong and durable. Coloured dyes can also be added after the printing process. SLS allows for plenty of design freedom as no support structures are required.
At the CNC Factory we use 3D System’s ProX SLS 6100. This allows us to produce some of the highest quality products in the industry.
SLS Nylon Ready to Print Volumes Guidelines.
- Make sure the parts do not exceed the stated volume.
- Make full use of your volume through tessellated stacking but ensure you leave a minimum of 2mm between each part.
- We clean every 3D printed volume with air and, for larger pieces, with sand for cleaning.
- Please bear in mind that our volumes may need additional powder cleaning on receipt and small pieces are often supplied in sliceable cages.
