After cleaning your resin model in isopropyl alcohol, the next step is crucial for achieving the best results. To soften the support connections, you can either submerge the model in hot water (approximately 50°C) for a few minutes or use an air gun to carefully apply heat for a few seconds. This process helps loosen the supports, allowing you to remove them more easily and with minimal risk of damaging your model.

The model is then cured and solidified under UV light.

When removing the larger supports, you might notice that a few smaller ones remain attached to the model. Additionally, there may be thin supports around intricate or detailed sections.

To remove these, use a precision cutter blade and carefully slice them off, ensuring the blade stays as close and aligned to the model's surface as possible.

Once all the supports are removed, you’ll notice some holes, marks, bumps, and lines on the surface.

Begin sanding with the coarsest sandpaper in the pack (240 grit). Gently work over the imperfections, taking care not to press too hard, as excessive pressure may damage or remove fine details. For tight or hard-to-reach areas, fold the sandpaper or use a sanding stick for precision.

Gradually move to finer grits until all scratches and imperfections are smoothed out.

For larger surfaces, use the sanding block with medium grit (around 500) for an even finish.
