Our SLA 3D Printing Services

Stereolithography or SLA is a resin-based 3D printing technology that produces highly accurate, high resolutions parts with an excellent smooth finish. The combination of high speed, low-cost per part and well-established materials makes stereolithography an ideal choice for prototypes and low volume production.

SLA Materials

High Temp Resin

We offer high-temp resin options. They are designed to be used in high-temperature scenarios such as ducting, molding, and for prototyping applications in the automotive and aerospace industries

Material Reference
YG H-3001, Lasty-702, GH100
Appearance
Grey, Yellow, Red Translucent
Sheet Metal Materials

Rigid Resin

Copper is an excellent material for sheet metal fabrication. It is malleable, ductile, and an extremely good conductor of both heat and electricity. It is commonly used for electrical equipment such as wiring and motors.

Material Reference
Red Copper, Brass
Appearance
Pinkish Orage, Reddish Brown, Reddish-Gold

Nylon-Like Resin

Taurus is a nylon-like SLA material that offers the look and feel of an injection moulded part. It has strong mechanical properties and is ideal for outdoor applications, casings and some functional prototypes.

Material Reference
Taurus
Appearance
Blue-gray (depending on finish)

Transparent Resin

At HLH, we can 3D print high aesthetic transparent parts. Transparent SLA resins are generally stiff. Because of the structure required to support your model during printing, freedom of design is limited.

Material Reference
Crysta-8QEF1, Godart 8001
Appearance
Transparent

Generic Resin

C-UV 9400 is an ABS-like SLA resin which has accurate and durable features. It can be applied in master patterns, concept models, general parts and prototypes in the field of automotive, medical and consumer electronics industries.

Material Reference
C-UV 9400
Appearance
White

High Toughness Resin

As the name suggests, high toughness resins are hard to break. Such SLA resins are extremely stiff, resistant to cyclic loads, and very strong, designed to withstand high stress or strain for short periods of time. High toughness SL resins can be applied in some functional applications.

Typical SLA Finishing Options

Whether it’s metal or plastic CNC parts. When cooperating with BOYI, we guarantee that all parts will be manufactured according to your specifications. 

Applicable Materials Colour Description
Sanding All Sanding SLA printed parts is often the best way of smoothing edges, removing blemishes, and getting rid of any leftover support marks.
Spray Painting All Black, Pantone/RAL colours Spray painting is a quick way to colour parts. It can also reach areas that cannot be reached with a brush.
Plating ABS Metallic Plating is method of adding a thin layer of metal of the outer layer of a material. It is used to harden, decorate and improve wearability of parts.

About The Process

SLA 3D printing builds parts one layer at a time using a highly accurate UV laser to solidify one layer of photosensitive resin, which makes the parts accurate and in good surface. The parts need to be built with support structures which are removed during post process. View the full overview of Stereolithography.Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Design For SLA

To achieve better part quality and end results, it is important that you design your part for the process. Learn how to design overhangs. assembly parts and more in our SLA 3D printing design guide.

Advantages of SLA 3D Printing

Wide Range of Materials – stereolithography offers a vast material selection with a range of properties.

Finest Detailing – SLA is one of the best 3D printing technologies for creating very accurate and finely detailed parts.

Rapid Turnaround – Because SLA can create complex and multi-material parts in a single operation, significantly less build time is needed vs. traditional manufacturing.

Smooth Finish – SLA creates parts with an excellent finish which remarkably resembles end use items like injection moulded parts.

Disadvantages of SLA 3D Printing

Generally Brittle – SLA parts are generally brittle and not suitable for many functional applications.

Degradation Over Time – Due to the photosensitive nature of SLA resins, SLA parts will experience degradation over time when exposed to sunlight.

Requires Support Structures – SLA prints always require support structures, which must be removed in the post-processing stage.

SLA FAQs

What is Stereolithography?

Stereolithography or SLA 3D printing is the most common resin 3D printing process. It has become very popular over the years due to its ability to produce highly accurate and watertight prototypes and end-use parts in a range of materials with fine features and smooth surfaces.

What type of material is used in SLA 3D printing?

SLA (or stereolithography) is a plastic 3D printing process that uses light-reactive thermoset materials called “resin.” The process offers a wide range of plastic material options that are often categorized by different material properties, including:

  • generic resin
  • transparent resin
  • high temp resin
  • rigid resin
  • high toughness resin
Which industries use SLA 3D Printing?

The many advantages of SLA 3D printing have made it a choice for many applications across different industrial sectors for many years, including:

  • automotive
  • consumer goods
  • gaming
  • robotics
  • medical
  • jewellery
Is SLA or FDM better?

SLA 3D printers use UV lasers to trace out the cross-sections of the model and form a object. This process creates a very high resolution, detailed printout, but it requires a longer print time. On the other hand, FDM (fused deposition modeling) creates parts additively using a filament. The process results in a lower quality printout, but they can do so faster. View the full comparison guide here.
