3D Printing

PRINTING PORTAL, specialise in SLA 3D Printing for fast and precise fabrication

We are able to print in a range of materials, from our standard range to engineering resins which offer enhanced properties designed to outperform in various situations

Combined with CAD expertise, 3D Scanning & Product Design, we can provide your required solution all in-house

3D Printing materials:

 
Standard Resin – Clear, White, Black & Grey. Good for displaying high detail
Castable – Castable Resin used for direct investment casting
Durable – Use to prototype models that will eventually be made from polypropylene
Flexible – Simulates an 80A durometer rubber
High Temp – Has an HDT of 289 °C @ 0.45 MPa. Good for thermoforming, vulcanization, and electronics encapsulation
Tough – Simulates ABS plastic. Choose for applications that will undergo high stress and strain

Which resin should you 3d print with?

Material advances for 3d printing technologies occur all the time, let us guide you with the latest materials as well as the latest techniques (combining 3d printing with other forms of manufacturing) to get the best result for your project.

Standard Resins

Clear: Transparency, polishes to near optical clarity, great for internal channels and working with light.

White: Neutral and matte tone, slight translucency when thin. Works well for sanding, and provides a great base color for painting prints.

Grey: Neutral and matte tone, great for showing off surface finish and for printing small, accurate features, photographs easily.

Black: Highly pigmented, our most opaque, high detail resin. Matte surfaces, great for printing small, intricate features.

Using Tough Resin

Tough Resin simulates the feel and many of the important mechanical properties of ABS plastic.

ABS (Acrylonitrile Butadiene Styrene) is a very common thermoplastic that provides a good balance of strength and flexibility. Tough Resin creates strong engineering prototypes and has been developed to withstand high stress and strain. Consider using this material for works-like prototypes and assemblies, including designs with snap fit joints and living hinges. For further finishing, Tough resin can also be machined once printed. Tough Resin can be printed at 50 and 100 micron layer heights.

Toughness refers to a material’s ability to absorb energy before fracturing. When a tough material yields, it will undergo some deformation rather than just shattering. In other words, tough materials have a little more “give” than brittle ones.

Toughness is also defined as the area under a stress-strain curve. Tough materials generally have a good balance of strength (the amount of stress a material can withstand) and ductility (the elongation or percentage strain). Because of this, the area under a tough material’s stress-strain curve is much larger than that of a very strong material with low elongation. This has a direct correlation to the amount of energy each material can absorb before failure. Tough Resin has lower stiffness than the Standard Resins while withstanding more elongation.
