TinyMaker Is a Palm-Sized Resin Printer That Runs on a Power Bank

A printer that fits in your bag

The TinyMaker is not a printer you would use to build a full-size phone case. At 100 by 115 by 155 millimeters and 600 grams, it is roughly the size of a takeaway coffee. What it does fit is a very specific niche: small, high-detail resin prints powered by a USB-C power bank.

The build volume measures 30.6 by 40.8 by 60 millimeters. That is tiny, but enough for miniature figurines, jewelry patterns, dental study models, and small electronics enclosures. Layer heights of 0.05 or 0.1 millimeters give it enough resolution for fine surface detail, even if the 240 by 320 pixel LCD screen is modest by modern standards.

Portable power and simple software

Power comes from a 5V, 2A USB-C input. That means you can run it from a standard power bank, making it genuinely portable. You do not need to hunt for a wall outlet when you want to print a small part in the field or at a maker event. Data transfer is via microSD card, not Wi-Fi, which keeps the firmware simple and reduces attack surface.

The printer supports Chitubox and PrusaSlicer, so software setup is straightforward for anyone who has already used a resin machine. It accepts standard third-party UV resins, which keeps running costs reasonable.

TinyMaker is on Indiegogo at the time of writing, with shipments expected in October 2026. It is open-source, with firmware, schematics, and 3D models released on GitHub. If you value portability over large build volume, this is an unusual and interesting option.
