Stereolithography – SLA Rapid Prototyping

Stereolithography (SLA prototyping) is a 3D Printing technology used for rapid prototyping and additive manufacturing.

SLA rapid prototyping is one of the most popular and versatile technologies offered by Prototype Projects and can be used to produce concept models, one-off presentation models and masters for use in Vacuum Casting.

A choice of delivery and finishing options are available on our SLA prototyping service.

Prototype Projects in-house SLA prototyping facilities

Prototype Projects operates a suite of SLA prototyping machines (one of which is dedicated to medical device prototyping) working round the clock, giving us the capacity to produce parts quickly and cost effectively with no compromise on build quality.

That means we can fulfil most SLA requirements to very tight deadlines with many jobs being delivered next day (depending on exact requirements).

We are currently the only Prototyping Bureau in the UK to offer SLA parts using Accura® PEAK™ Resin from 3D Systems. Accura PEAK offers properties including high stiffness, moisture stability and temperature resistance.

Stereolithography Process

SLA prototyping is a 3D printing process used in rapid prototyping, and is typically used early in the product development process as concept or one-off presentation models and masters.

It produces parts with good quality smooth surface finish, excellent optical clarity, high accuracy and thin, straight, vertical walls.

The range of materials that can be used allows for a range of tolerances and property resilience.

When to Use Stereolithography

Stereolithography (SLA) is ideal for low or single run production of prototype parts for concept models, presentation models or tooling masters that are required quickly and cost effectively.

Depending on the exact requirement, parts can typically be produced overnight for delivery next day.

SLA machine, ProJet 6000Pre-production applications for which SLA is ideal include:

  • Concept models
  • Presentation models
  • Investment castings
  • Master patterns

Stereolithography Process Benefits

In the overall product design and development cycle, SLA is a vital process for helping your get your products to market fast.

Speed: SLA is one of the most popular prototyping processes among product designers and design engineers as it enables them to get their designs off the drawing board and on to the table quickly. Depending on exact specifications, SLA models can be turned around overnight

Low cost: SLA prototyping is one of the cheapest prototyping processes, which means that SLA parts can be thrown away and designs modified prior to moving further into the higher cost stages of the production process

Cost effective small numbers: Single parts can be produced quickly and easily

Tight tolerances: parts can be produced to very specific requirements

Broad range of part properties:

  • High temperature resistance
  • Moisture resistant
  • Clear, white or translucent; colour finishing available
  • High level of feature complexity
  • Excellent surface finish
  • Range of model sizes
  • Lathing and drilling options
  • Flexible polyurethane casting resin grades range
