SLA (Stereolithography)

Why SLA?

Stereolithography (SLA) is an additive manufacturing process that is a good choice for aesthetic models, fit-and-form prototypes, exhibition models and master patterns for the vacuum-casting process.

This is a high-accuracy process, capable of producing crisp detailing with a range of available materials. SLA parts can be hand finished and painted in a full range of colours and finishes to look like production parts. The ability to print clear parts makes SLA an ideal technology for prototyping optics, transparent covers and flow visualisation models for a range of industries. 

SLA produces parts layer by layer to form a complete 3D object direct from 3D CAD data via an .STL file. The process employs a solid-state laser, which traces the required shape across the surface of a vat containing photopolymer – curing the layer of material it contacts. 

Benefits of using SLA include:

• Quick turnaround of parts 
• Crisp detail and smooth surface finish 
• High level of accuracy 
• Ability to print complex geometries 
• Low cost 
• Wide range of post-processing options, including hand finishing and painting, assembly, incorporating threaded inserts, plating etc.

SLA at Ogle:

Ogle has been producing SLA parts since 1996 and currently has four industrial SLA machines – two Stratasys Neo800s, one Neo450s and a 3D Systems Ipro 8000 – with the largest build volume being 800 x 800 x 600mm. The sky really is the limit for your SLA part. For your colour, texture or design effect, Ogle has a dedicated paint facility with a full-sized finished booth (6.25 x 3.9 x 2.5m) and a highly skilled team who can create stunning and visually accurate models and prototypes.  

What Ogle offers: 

• Large frame machines, allowing for extremely large parts to be printed as one piece, or a quick turnaround of smaller parts at volume. Parts larger than the build volume can also be assembled post print, if required. 
• The human touch. We don’t just print your parts, we can advise of the best material, process and geometry modifications, if required, including wall sections and feature definition. 
• Inspection facilities using calibrated equipment with various reports available, including CofC and FAIR. 
• Post-processing by our skilled team – including surface finishes, painting, assembly and inserts.  

Variety of materials: 

• EvoLVe 128 (white) 
• MPC 12 (clear) 
• ClearVue 
• Other specialist materials, such as ceramic-filled resins, available upon request
