Formfutura Tough Resin is an engineering type of photopolymer resin that is specially developed to work with all open source SLA, DLP, and LCD 3D Printers in the range of 385 – 405nm. Our Tough Engineering resin is extremely transparent and perfectly balances a high impact strength with semi-flexibility. 

Its high level of toughness makes Formfutura Tough Resin ideal for creating strong and functional parts that will be exposed to repeatedly brief periods of intense stress or strain

Key features

• High impact resistance
• Good UV and weather resistance    
• Good fatigue resistance
• Extremely transparent with virtually no discolouration and/or yellowing
• High dimensional accuracy and low shrinkage
• Almost odourless processing
• Compatible with all open-source SLA, DLP, and LCD 3D printers in the range of 385 - 405nm

Applications

• Snap-fit assemblies
• Tooling
• Functional prototyping
• Protective cases
• Outdoor parts
• Short-run manufacturing

Resin properties (uncured liquid)

Mechanical properties

Test method on post cured objects through 10 minutes high power mercury curing.

Please note that the above-displayed values can vary with individual machine processing, post-curing parts,  geometry, print orientation, print settings, and temperature.

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
• Make sure that IPA and/or (Bio)Ethanol rinsed objects are perfectly dry before further post-curing
• Cure your object in a high power curing chamber for approximately 20-30 minutes at 65° C

• An ultrasonic cleaner is preferred/recommended

• Place the rinsed parts in a well-ventilated area for at least 30 minutes, or use pressurized air for at least 2 minutes

• 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.
