Usage Tips and Best Practices:

To get the best results from the GKTwo, consider these tips:

• Resin Selection: Experiment with different resins. While the GKTwo is designed for 405nm resins, the specific resin formulation can significantly impact print quality. Consult online communities and forums for recommendations based on your desired properties (strength, flexibility, etc.).

• Slicing Software: ChiTuBox is the recommended slicing software, and it offers a wide range of customizable settings. Take the time to learn the software and understand the impact of parameters like layer height, exposure time, and support structures.

• Support Structures: Generate ample support structures. Resin printing requires careful consideration of support placement to prevent print failures. Pay attention to overhangs and areas with small surface contact. Experiment with different support densities and thicknesses.

• Exposure Time: Calibrate your resin by printing a small calibration test model. Dial in the correct exposure time. Too little exposure leads to incomplete curing, while too much can cause dimensional inaccuracies and excessive resin sticking to the FEP film.

• Bed Leveling: Ensure the build plate is perfectly leveled. Leveling should be done before every print.

• Resin Vat Maintenance: Clean the resin vat regularly with IPA to remove any cured resin residue or debris.

• Post-Processing: Post-processing is crucial for resin prints. After printing, wash the model in IPA to remove uncured resin, then cure it under UV light to achieve its final hardness and strength. Use a dedicated UV curing station for best results.

• Ventilation: Resin printing produces fumes, so it’s essential to use the printer in a well-ventilated area. Consider using a fume extractor or enclosure to minimize exposure.

• Proper Resin Storage: Store resin in a dark, cool place in an airtight container.
