“We have used SGD 3D a few times now. Each time they dealt with our queries promptly, giving us all the information and help we needed as a new user of Additive Manufacturing” – Howmet Aerospace

What is SLA 3D Printing?

Stereolithography (SLA) is an industrial 3D printing process that is ideal for manufacturing low-volume parts or prototypes. In FDM, wire-fed stock material is heated and extruded to build geometry layer-by-layer.

SLA machines can produce high-quality plastic parts in materials with varying properties including; chemical resistance, flexibility, fire retardancy, high temperature resistance, etc.

Manufacturing standards for SLA 3D printed parts

We manufacture your custom parts according to strict manufacturing standards and ensure all parts and processes adhere to the clear guidelines. A thorough verification of these requirements is included in our inspection report that we ship with every order.

Product Design & 3D CAD Design

BENEFITS

ACCURATE

Parts are produced to a dimensional accuracy of ± 0.1% with a lower limit of ± 0.075 mm

SOLID PARTS

Parts are printed solid by default, excellent for retaining liquids & ensuring maximum strength 

SMOOTH

Surfaces are smooth, due to minimal layer heights. Great for simulating moulded parts

ISOTROPIC

Identical & consistent material properties in all given directions at every given point (x, y, z axis) 

SMALL DETAILS

Features as small as 0.1mm can be successfully printed using SLA, perfect for small parts

Advantages and drawbacks of SLA 3D printing

SLA RESIN 3D Printing Service

Advantages

  • SLA can produce parts with very high dimensional accuracy and intricate details.
  • SLA parts have a very smooth surface finish, making them ideal for visual prototypes.
  • Speciality SLA materials are available, such as clear, flexible and castable resins.
Form_Printed_Parts

Drawbacks

  • SLA parts are generally brittle and not suitable for functional prototypes, though industrial SLA can produce more functional components for this stage.
  • The mechanical properties and visual appearance of SLA parts will degrade over time when the parts are exposed to sunlight.
  • Support structures are always required and post-processing is necessary to remove the visual marks left on the SLA part.

SLA 3D PRINTING - FREQUENTLY ASKED QUESTIONS

Is resin 3D printing expensive?

Depending on the size, geometry, and material, resin 3D printing can be cost-effective. However, our costing model works off material volume; the higher this value, the more expensive your part will be! Check out our article on tips to help you reduce your part costs

Is resin 3D printing food safe?

The answer is no. Resins are toxic, and substances may migrate from SLA parts, no matter what the level of post-processing (UV + thermal). Some resins are certified as biocompatible; however, this in no way means that they’re food safe. Some food contact safe coatings are available; however, we don’t recommend using these as the coating may interact with the resin or degrade over time.

What is resin 3D printing?

SLA (Stereolithography) or resin 3D printing is the process in where liquid photopolymer resin is cured using a light source, in this instance, a small laser. Using pre-determined geometry, it’s able to accurately produce incredibly small & detailed parts.

Is resin 3D printing strong?

We have several different material options available at SGD. Some of these resins are created with functionality in mind, and we have materials that simulate the rigidity and stiffness of PEEK, ABS & PolyPropylene.

Is resin 3D printing safe?

Resin in its raw form is toxic, however, all parts produced at our 3D printing service are professionally post-processed. All resin printed parts are washed in an IPA bath and UV + thermally cured as specified by our material supplier.
