SLA 3D Printing

About 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 - a part emerging from the resin.

Applications of SLA

  • 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.
  • Waterclear models including lenses and light-guides.

Benefits of SLA 3D Printing

  • SLA has a high resolution.
  • Often 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 508 x 508 x 580mm.
  • Ultra Hi-res mode utilises the lasers extremely small spot size of just 0.075mm.
  • Offers the best surface finish for additional finishing.

Levels of Clarity in SLA 3D Printed Parts

Exploring the differing levels of clarity that can be achieved on the SLA machines at MNL.

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?
