A printer for children and a filament that is not TPU

The SainSmart printer

The PrintyGo Mini is written for parents: enclosed, a door that stops the print, no computer needed. It publishes no build volume or temperatures.

The SainSmart filament

A PEBA 90A elastomer stated to be lighter than TPU and to return more energy, for dual-gear extruders, with no temperatures or tolerance.

    SainSmart PrintyGo Mini, enclosed printer for children

    No build volume published · fully enclosed with a door that stops the print · auto-levelling · 5 inch touchscreen · Wi-Fi and app · 600 mm/s maximum stated

    A pre-assembled, fully enclosed printer sold as a STEM toy for children aged 8 and up, whose door stops the print when opened, and whose listing never states how large a part it can make.

    Best for: A supervised first printer for a child from eight, where an enclosed frame and a door that stops the print matter more than size.
