Do I Need a Rotary Polisher for Formlabs Resin?

Polishing Formlabs resin to a glossy finish is a rewarding final step for any project. But do you really need a rotary polisher to achieve professional results, or are there simpler options for hobbyists and small-scale crafters?

Is a Rotary Polisher Necessary?

A rotary polisher is an excellent choice for achieving a mirror-like gloss, especially on larger resin surfaces or intricate professional pieces. It offers speed, consistency, and helps minimise swirl marks when combined with a quality polish system such as Epoxy Polish. However, for many smaller or detailed items, careful hand polishing using suitable pads or a microfibre cloth can be just as effective, particularly when patience is exercised and the correct products are used.

Effective Alternatives for Hand Polishing

If you don’t have a rotary polisher, progressive sanding with fine grits (such as using Ebonite Abralon Sanding Pads) followed by buffing with a polishing cream and sponge discs can yield excellent results. Using a hand pad holder or a microfibre cloth helps you control the pressure on smaller areas, reducing the risk of over-polishing. Ensure you start with the finest abrasive your surface needs and finish with a clean, soft pad for the best possible shine.

When Does Polishing Equipment Matter?

The choice between rotary and manual polishing comes down to project size and your desired finish. Rotary tools are most beneficial for larger, flat pieces or when consistent gloss is critical. If you’re working on delicate, small, or irregular resin parts, hand methods offer superior control and can help avoid inappropriate abrasion or accidental damage.
