BioResin™ Resin Colour Options
BioResin™ Grey
Grey’s neutral tone enhances visibility and detail, making it an excellent choice for prototypes and functional models. Its muted shade provides exceptional contrast, highlighting intricate features and enabling easy inspection of fine details. Grey also serves as an ideal base for painting, offering a consistent surface for adding custom finishes. This versatile colour is perfect for design iterations, architectural models, and engineering prototypes.
BioResin™ Almond
Almond’s warm, natural tone adds an organic aesthetic to 3D prints, making it an excellent option for artistic creations, figurines, or models that benefit from a softer, more approachable appearance. The subtle shade reduces glare under bright lights, improving visibility during the printing and inspection. Almond is also highly forgiving for showcasing surface textures and is well-suited for applications where the result needs to exude a refined, elegant finish.
BioResin™ Clear
Clear offers good transparency, ideal for creating parts where internal structures need to be visible or for functional prototypes requiring light transmission. It is perfect for applications like lenses, fluid flow models, or showcasing internal mechanisms. The clear finish allows easy post-processing, such as polishing, to achieve an even higher transparency. This versatile option is also well-suited for creative and decorative projects, offering endless possibilities for innovation.
Expert Tips for Printing with BioResin™
Prepare Your Resin
Ensure the resin is at room temperature and well-mixed before use. Shake the bottle thoroughly to achieve consistent results across your prints.
Calibrate Your Printer
Use calibration models to fine-tune your printer settings for BioResin™, ensuring high accuracy and precision.
Post-Cure for Durability
After cleaning, post-cure your models under 405nm UV light for 20–30 minutes to enhance strength and long-term stability.
Use Supports Strategically
Angle models on the build plate and use well-placed, dense supports to prevent warping and ensure flawless prints.
Optimising Your Prints with BioResin™
BioResin™ delivers exceptional performance across various applications, supporting layer heights from 10 to 200 microns to suit detailed, larger-scale prints. For optimal results, models are best printed solid, but if hollowing is required, ensure strategically placed drain holes to prevent resin from becoming trapped and to improve post-print cleaning.
When preparing your model, angle it slightly on the build plate to reduce large flat surfaces that may cause adhesion issues with the FEP film. Use dense, well-placed supports to secure overhangs and unsupported areas, ensuring structural integrity throughout the print.
BioResin™ is formulated for efficiency, often requiring slightly faster exposure settings than standard resins. Adjust your printer settings to match these requirements, and take advantage of the calibration tools available on our website to fine-tune your setup.

Post-Processing Guide for BioResin™
1. Cleaning with ResinAway®: After printing, immerse your model in a pre-wash bath filled with ResinAway® to remove uncured resin. Use a soft brush to gently clean the surface, ensuring intricate details are not damaged. For complex designs or hard-to-reach areas, place the model in an ultrasonic cleaner filled with ResinAway® for 5-10 minutes for a thorough clean.
2. Drying the Model: Once cleaned, ensure the model is completely dry by using compressed air to blow off any remaining liquid or patting it gently with a lint-free cloth. Avoid leaving residual ResinAway® or moisture on the model, as this can lead to surface imperfections or cracking during curing.
3. Post-Curing for Strength: Place the model in a curing chamber equipped with a 405nm LED UV light. Begin with a brief exposure to cure the surface evenly. Rinse the model with fresh water to remove any remaining ResinAway® residue before continuing for optimal results. Return the model to the curing chamber for at least 30 minutes to enhance its mechanical properties, including tensile strength and durability.
4. Finishing Touches (Optional): For projects exposed to external elements, consider applying a protective paint or coating to improve longevity. BioResin™ models can be machined, sanded, or polished to achieve a smooth, scratch-resistant surface, making them suitable for professional and display-ready applications.
