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.
Claims18
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, wherein said finger detector is mounted to said gripping handle to detect a finger movement at a lateral side of the said gripping handle.
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;
- wherein said finger detector is received within said sleeve, where said sleeve comprises one of a placing area that is made of a transparent material and a window to allow the detecting light from said light emitter to pass therethrough to reach the finger of the user.
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;
- wherein said filament moving system comprises a driving motor and a filament moving blade, wherein when said driving motor is in operation, said filament moving blade, which is inclinedly provided with respect to the filament, is driven to move back and forth to drive the filament to move forward when said filament moving blade is moving forward.
