Abstract
A 3D drawing arrangement includes a sleeve, a gripping handle, a feeding passage, a heater, a filament moving system, and a controller which includes a control circuit and a finger detector electrically connected to the control circuit, wherein when the finger detector detects a presence of a finger of a user which is aligned with the finger detector, the control circuit starts operation of the filament moving system to feed a filament to the heater along the feeding passage, so that the filament is heated and melted by the heater to produce the melted material flow.

A 3D drawing arrangement for producing a melted material flow by a filament, comprising:
- a sleeve;
- a gripping handle coupled to said sleeve;
- a feeding passage disposed in said sleeve;
- a heater;
- a filament moving system;
- and
- a controller which comprises a control circuit and a finger detector electrically connected to said control circuit, wherein when said finger detector detects a presence of a finger of a user, said control circuit starts operation of said filament moving system to feed the filament to said heater along said feeding passage, so that the filament is heated and melted by said heater to produce the melted material flow.
