3D Printing Services Utilising Our SLA Services

Malcolm Nicholls Ltd are the industry leaders in 3D printing services, with over 50 years of experience in rapid prototypes and low volume production methods, we can produce or manufacture anything from 1 – 1000’s of parts.

We have two of the largest 3D Printers in the UK

Home to one of the largest 3D printers in the UK our Neo 800 has an impressive 800 x 800 x 600m build capacity. Whereas most other stereolithography companies with SLA 3D Printing machines previously would have required large parts to be built in sections, we now have the ability to build parts without the need for cutting meaning parts are built quicker, finishing is streamlined and is cost-effective.

What is SLA 3D Printing & Stereolithography?

Stereolithography (SLA) also often referred to as SLA is the most widely used resin 3D printing technology and it is generally considered to provide the greatest accuracy and best surface finish of any prototyping or 3D printing process. Stereolithography is an industrial 3D printing process used to create concept models, complex or even very intricate parts. It is a popular choice as many parts can be built in just a day! With MNL’s secondary finishing services such as painting and finishing we can make your part and the details within it really stand out.

How does SLA 3D printing work?

A computer controlled UV laser beam scans across the surface of a vat of photosensitive resin that instantly turns the liquid to solid wherever it touches. Successive layers or slices of cured resin are gradually built up into a solid version of the intended CAD model until your part is complete. 

Newly built parts are taken out of the SLA machine and taken into our processing room where solvents are used to remove any additional resins. The additional resin will all be removed so we can then remove any support structures manually. After the supports and all the resin has been removed the majority of parts will undergo a UV-curing cycle to fully solidify the outer surface of the part. If the part is a clear 3D printed part we will leave it to dry naturally.

The final step in the SLA 3D printing process is the application of any specified finishing touches such as metalising, painting, flocking or additional vinyls.

Why Choose to do your 3D printing via SLA?

Stereolithography or SLA is also an excellent choice for rapid prototyping and projects requiring the production of very accurate and finely detailed parts. Stereolithography prototyping is ideal for creating parts to demonstrate and validate concept ideas and ergonomic testing.

Large parts? Utilise an SLA printing service

MNL’s resin 3D printing service in the UK is home to two of the UK’s largest 3D printers. With an impressive build platform of 800 x 800 x 600mm we can produce first-class large frame parts quickly. Offering best-in-class; exceptional part sidewall quality, with a scanning resolution to within 1 micron, our NEO800 systems significantly reduce finishing times by up to 50%. NEO800 has a variable spot-size laser. It goes small for intricate detail on the boundaries of parts and then it goes larger for filling in the rest of the section. As a result, this combination of intricacy and super-fast build speeds produces excellent quality components in super quick time frames.

Virtually optically clear SLA 3D printed parts?

Our team of 3D printing experts have mastered virtually optically clear parts from our Stereolithography machines, we can help you see inside your assembly, utilised by many of our clients for flow testing and analysis as well as replicating glass for many designs. Glass like SLAs can be achieved with MNL not just for lenses and lighting based components.
