SLA 3D Printing

In Stereolithography (SLA)  a  laser precisely cures each layer of a design into UV-sensitive resin.

It is one of the most tried, tested and efficient industrial 3D printing techniques and serves as the foundation of rapid prototyping.

Highly-Detailed

Fast Process

How Stereolithography Works

Stereolithography builds a part layer-by-layer using UV sensitive resin and a high-power laser.  

  1. 3D CAD file is reviewed by the AME-3D production team  
  2. CAD file is set-up in the SLA system  with required supports 
  3. UV laser beam selectively hardens the resin based on the file specifications 
  4. The  machine builds the 3D part one layer at a time
  5. After the  build is complete, the  part is processed according to the chosen finish 

Cost-Effective

Rapid Prototyping

SLA Applications and Uses  

  • Master parts for rapid prototyping 
  • Visual prototypes for investment pitches and stakeholder buy-ins  
  • Functional prototypes for concept testing 
  • Individual part form and fit testing   
  • Durable materials ideal for on  demand  parts 
  • Housing consumer electronics 
  • Medical devices  
  • Transparent assemblies such as headlamps or bottles

SLA Printed Parts

SLA printed parts play a big role in on  demand  manufacturing. 

3D printed parts are an ideal choice, if you require an end-use part due to demand volatility or  an unexpected delay in your supply chain.

 The benefits of SLA printed parts are:  

  • High-speed 3D printing    
  • Part production repeatability 

Benefits

Stereolithography is  a highly versatile 3D printing technique that bridges the gap  of rapid prototyping and on demand part manufacturing.

Its main benefits include:  

  • Fine detail and high resolution  
  • Precision 
  • Repeatability
  • Smoother  surface finish compared to FDM 
  • Cost-effectiveness 
  • Fast process  
  • Wide variety of uses
