Benefits of technology

The present invention provides a material level detecting mechanism for a three-dimensional system. It uses first and second detecting units to detect the downward movement of the printing cartridge. Alternatively, it includes first and second pistons that trigger the detecting units and push the modeling material downwards. The detecting units also track the initial and termination positions of the piston along the printing cartridge. This allows for accurate measurement of the amount of modeling material usage without the need to detach the printing cartridge from the system.

Problems solved by technology

However, in the current 3-D printing apparatuses which uses refillable cartridges, the usage or remaining amount of the modeling material of the printing apparatus is often hard to be detected or defined or not being detected at all.
Moreover, there were not a system or apparatus existed to inform the usage or remaining amount of the modeling material of a 3D printing apparatus simultaneously.
The detachment processes of the current printing heads are often time consuming, manpower intensive, and costly.
As a result, to some extent, the current 3-D printing process is still inconvenient and expensive in terms of maintenance and cost of the equipment operation.

Abstract

A material level detecting mechanism of three-dimensional system includes a bracket, a printing head, first piston, a second piston, a first detecting unit and a second detecting unit. The bracket includes an aligner holder and a supporter. The printing head detachably located in the aligner holder, and including a nozzle with an outlet for extruding the modeling material. The first piston includes a piston rod attached to a piston head, and the second piston slidably located inside the cartridge is adapted to be pushed by the first piston toward the direction of the outlet. The first detecting unit is adapted to detect the home position of the first piston and the second detecting unit is adapted to detect the touching of the first piston and the second piston which provide the initial amount of material present in the cartridge which is subject to print.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The technical field relates to a three-dimensional system, and more particularly to a material level detecting mechanism having detection units for obtaining the dispensing amount of the modeling material.[0003]2. Description of Related Art[0004]With advancement in computer-aided manufacturing (CAM), a three dimensional printing technology (3-D printing technology) has been developed in the manufacturing industry, thereby rapidly fabricating products from an original design concept. The 3-D printing, in fact, is a general term of a series of rapid prototyping (RP) techniques, and the basic principle thereof, and the concept thereof is a laminate manufacturing, wherein a rapid prototyping machine is used to form cross-sectional shapes of a workpiece in the X-Y plane through scanning, shift intermittently at a layer thickness in the Z coordinates, and ultimately form 3-D objects. The 3-D printing technology is unrestrictedly app...
