As amazing as 3D printed objects are, some of them do have a sort of Achilles Heel; they show their method of construction in the form of visible layering, and that's not always right for every client and application.

To mitigate the "layered look," objects printed of ABS and PLA via FDM require finishing to get the magically smooth look most designers require of a finished product. It can be time-consuming and tedious work indeed.

But now the MagicBox promises mass finishing for ABS and PLA 3D prints and it is available on Kickstarter.

The MagicBox makes use of an acetone vapor bath to smooth the lines normally present on FDM prints via a simple, easy-to-use interface with settings giving users control over the look and feel of their finalized prints.

The designers say using the MagicBox is a pretty simple process: fill the reservoir built into the device with acetone, place a clean print into the chamber, adjust the settings and press start.

Voila. Smooth FDM print accomplished.

The MagicBox uses a patent-pending process to quickly evaporate acetone. Once the vapor fills the chamber and begins to smooth out the surface lines from of your FDM prints, an exhaust fan and filter system captures excess vapor to ensure that the air in your room stays clean and fresh.

The MagicBox is a compactly designed unit which offers a switch on the control panel which lets users control the acetone vapor to leave surfaces very smooth (at the cost of some loss of detail) or lessen the effect to preserve detail.


  • Total Size: 30cm x 30cm x 29cm
  • Chamber Size: 25cm x 25cm x 20cm
  • Weight: 5kg
  • Power: 100-240V A/C, 50/60HZ
  • Works with: ABS, PLA

The designers say they wanted the MagicBox to take up a place right next to a user's 3D printer, so they made it about the size of a 17 inch monitor.

Eric Huang, the founder of Sky Tech Co., Ltd, and the mover behind the MagicBox, has a background in mechanical engineering and started a 3D printer business in 2012. Huang has made it his goal to develop tools that work in conjunction with 3D printers, and his latest obsession is the MagicBox.
