Key Features

Ultra-Low Viscosity: Our PRO Light Grey resin boasts an ultra-low viscosity, ensuring the capture of even the finest details in your prints. This feature guarantees that intricate designs are rendered with exceptional clarity and precision.

Enhanced Build Plate Adhesion: Bid farewell to print failures. The resin’s superior adhesion properties ensure a steadfast grip on the build plate, providing consistency and reliability in every print.

Stable Pigmentation: Experience uninterrupted printing with no pigment settling or separation, even during prolonged print jobs. This ensures uniform colour and properties throughout your prints, from start to finish.

Rapid Cure Formula:Time is of the essence, and our rapid cure formula significantly accelerates printing speed without compromising on quality. Achieve faster results and increase your productivity effortlessly.

Tuff Base for Increased Strength: The incorporation of a Tuff base material in our Light Grey resin enhances tensile strength, resulting in prints that are not just visually stunning but also robust and durable.

Versatile Printing Layer Heights: Adaptability is key. Our resin is compatible with layer heights ranging from 10 to 100 microns, offering flexibility to cater to various printing needs and preferences.

Low Reaction Temperature: Protecting your equipment is as important as the print itself. The low reaction temperature of our resin extends the longevity of your LCD screen, ensuring sustainable and cost-effective printing.

Proudly Australian Made & Guaranteed: All our resins are expertly developed and manufactured in Australia, embodying our commitment to high-quality, constancy and trust. Our experienced chemists ensure each product meets rigorous standards. Plus, with our MonoBACK guarantee, you have the confidence to buy, try, and return if not completely satisfied. Experience the Monocure3D difference with every purchase.

Whether you’re a professional seeking the highest quality in your prototypes, models, or intricate designs, Monocure3D’s Pro Light Grey resin is your go-to choice. It’s more than just a resin; it’s a commitment to quality, efficiency, and durability in every print.

Experience the difference with Monocure3D PRO Resin Range – where every layer is a masterpiece.

Now anyone can 3D Print like a PRO

One of our original PRO resins, a truly clear 3D Printing resin! Formulated using our advanced urethane base, this unique product allows you to print parts with outstanding clarity, strength and durability.

You asked for it, so our chemists delivered it. The first real dense black 3D Printing resin on the market. A heavily pigmented resin that lives up to its name without compromising the print details.

Finally, a true rubber-like 3D Printing Resin, taking flexible materials to the next level! This resin has a unique composition closely resembles rubber in elasticity after post-processing with the ability to stretch to over 166% and return to its original shape.

Our famous Glow in the Dark Resin took 12 months to develop! It was formulated to be the longest glowing 3D printing resin on the market (guaranteed to glow all night).

About our PRO Resin Range

Our PRO resins were specifically developed for those wanting professional results. All our Enduro resin products in the PRO range are built using our advanced in-house developed polyurethane base material, ensuring tough, long-lasting models with no shrinkage or warping, plus more tolerance to heat & UV exposure. Our range of unique, reliable PRO resins has been formulated to help you work faster and print professional-looking parts every time.

You don’t need to look further than our PRO range when you need products with superior quality and batch-to-batch consistency.


The tensile modulus of a solid material is a mechanical property that measures its stiffness.


Tensile elongation is the stretching that a material undergoes as it is pulled in tension.


Tensile Springback occurs as atoms revert to their equilibrium positions following elastic deformation.

Always shake resin well before printing. It’s recommended to wait for the surface bubbles to pop before starting your print. PROTIP: A lighter or heat gun can speed up this process.

The new large format printers can 3D Print massive models but have tend to have low volume vats. Ensure you have enough resin to complete the print job, and remember to top up the resin vat if necessary.

When stored correctly, Monocure 3D resins can last up to 36 months. Remember to keep your resin in its original bottle, in a dark, cool place away from direct sunlight. Do not allow the materials to freeze.

For the best result with Crystal Clear, always post-cure using 405nm UV light for a short time only. Polishing or using a clear gloss acrylic spray paint, will give you see-through results.

All Monocure 3D PRO resins are versatile and can be printed between 10 and 100-micron layer heights. To achieve the best results, 3D models should always be designed solid. If hollowing is required, ensure drain holes are included to remove any trapped resin.

Check our printer setting page to see if we have your printer listed to give you a good starting point. (Not all slicers have this setting, check with your software provider). Use a calibration model to dial in your printer with our resin.

Wash Up



For best results after printing, use ResinAway® to remove uncured resin from the part. Place part in a pre-wash bath filled with ResinAway® and use a soft brush to remove excess resin. Follow by placing the component into an ultrasonic cleaner with ResinAway® for 3-5mins to help remove the resin trapped in the finer detail.

  1. Ensure parts are dry by using compressed air or patting gently with a lint-free cloth before post-curing – Warning: leaving excess IPA or ResinAway® on parts might result in surface cracking.
  2. PRO™ resin requires post-curing to reach its optimal mechanical properties. We recommend using a 405nm LED Ultraviolet light to post-cure the model. It is recommended to post-cure for a few minutes, then remove the excess ResinAway® by washing with fresh water. Then place it back in the curing chamber for at least 30 mins to improve the tensile strength of the resin.
  3. When exposing a part to external elements, apply paint to the surface to improve longevity. Alternatively, the components can be machined, sanded and polished to create a tough, scratch-resistant surface.
