The Engineering SLA Resin – Heavy Duty is one of the strongest resins on the market. It combines flexural strength with durability and heat resistance. Parts printed with this resin show great resistance to continuous built-up pressure. This resin is perfectly suitable for applications that need strength, stiffness and heat resistance.
Key features
- Flexural strength of 135 MPa
- Stiff and durable
- High heat resistance of 128°C
- High dimensional accuracy and low shrinkage
- Almost odorless processing
- Compatible with all open-source SLA, DLP, and LCD 3D printers in the range of 385 – 405nm
Applications
- Tooling
- Jigs and fixtures
- Manufacturing aids
- Mold masters for low volume injection molding
- Functional prototyping

Preparation(s) before starting to print
- Shake the bottle for at least 2 minutes before each use
- After shaking the bottle, leave the resin to rest for 10 minutes to let air bubbles get out of the resin
- The resin can be poured back from the vat into the bottle once your print is finished
- Always use protective measurements like safety glasses and nitrile gloves when handling resins
Post-processing
We do advise you to post-process your 3D print in order to achieve the material properties.
- Rinse your 3D printed object in IPA or (Bio)Ethanol for approximately 5 minutes
- An ultrasonic cleaner is preferred/recommended
- Make sure that IPA and/or (Bio)Ethanol rinsed objects are perfectly dry before further post-curing.
- Place the rinsed parts in a well-ventilated area for at least 30 minutes, or use pressurized air for at least 2 minutes
- Cure your object in a high power curing chamber for approximately 20-30 minutes at 65° C
- The preferred curing wavelength is between 300-410nm
Safety
Please always be aware that when 3D printing with resins that you are working with chemicals and that you should always be cautious and use the personal protective equipment as stipulated in our safety data sheets.
- Always wear Respiratory Protection when sanding/cutting the resin object
- Always use nitrile gloves when handling resins and uncured resin objects
