3D printing and rapid prototyping technology

What is SLA 3D Printing & Stereolithography?

Stereolithography or “SLA 3D Printing”, is the most widely used 3D Printing / rapid prototyping technology. It is generally considered to provide the greatest accuracy and best surface finish of any prototyping / 3D printing process.

A computer controlled UV laserbeam scans across the surface of a vat of photosensitive resin instantly turning liquid to solid wherever it touches. Succesive layers or slices of cured resin are gradually built up into a solid version of the intended CAD model.

SLA 3D Printing Applications

  • Master patterns for polyurethane castings
  • Aesthetic & conceptual models
  • Parts requiring crisp detail and accuracy
  • Quickcast™ investment “wax” patterns
  • Design evaluation models
  • Clear Flow analysis models
  • Water clear models including lenses and light-guides

What are the benefits of SLA 3D Printing?

  • SLA has a high resolution
  • 3D models can be sanded, painted, & tinted
  • Prototypes can be made in a matter of hours
  • Extremely durable material making it excellent for snap fits
  • MNL’s machines have a maximum build capacity of 800 x 800 x 600mm
  • Ultra Hi-res mode utilises the lasers extremely small spot size of just 0.075mm
  • Offers the best 3D surface finish for additional finishing

Levels of Clarity

Being Clear About SLA

Not just used for lenses and lighting based components. See inside your assembly with a clear version of your housing. But how clear do you need it, or how much will it cost? An excellent illustration of examples and uses of making SLA parts in clear materials.
