Problems solved by technology

[0008] However, it is quite time-consuming to produce each layer of the object, because although the motion path that the laser cutting head sweeps on each page has been programmed into the computer control system, the cutting head still has to follow the path of the page. The required cutting path on paper is moved mechanically
High quality layered prototypes can be produced with this system, although for prototypes of moderate complexity, layering and cutting all the required sheets can still consume 36 hours or more

Embodiment Construction

[0212] First, see figure 1 to Figure 5, figure 1 A page of paper 10 is shown, on which an outline 20 will be printed, and the outline 20 will become a part of the pyramid-shaped three-dimensional prototype 30 described in FIG. 10 is imprinted with a matrix of lines 11 dividing most of the remainder of the paper 10 into small squares, it being understood that cutting the paper 10 along the lines 11 will remove the remainder of the paper 10 around the outline 20.

[0213] Figure 2 shows the second sheet of paper 12 with the outline printed on it Figure 22 , the size is slightly larger than the profile 20 of the paper 10, and the line matrix 13 is also printed on the paper 12, and the profile Figure 12 Most of the area outside the paper 12 is divided into small squares.

[0214] exist image 3 In , the contour map 24 on the paper 14 is slightly enlarged, the line matrix 15 is similar to the line matrix 13 in Fig. 2, and Fig. 4 shows that the paper 16 has a printed contour ...

Abstract

The present invention provides an improved process for manufacturing laminated objects. Said process comprises printing a desired skeleton map (67) at a substrate (e.g. paper), wherein the printing can be performed by utilizing a laser printer (66) and the like. After that, the printed substrate is felted (70), and enough energy (68) is applied to the printed skeleton map (67) to eliminate substrate at positions of skeleton map (67) to form a three-dimensional object which can be used as a module or a prototype or an actual workpiece.

Description

technical field [0001] The invention relates to the field of object manufacture. Background technique [0002] It is well known that laser technology can be used to manufacture workpiece objects, such as parts that need to be precision manufactured in order to cooperate with other parts, as well as prototypes. In the past, such parts and prototypes were generally made by skilled craftsmen from wood, plastic or similar materials, or were machined from solid metal to form these objects. Both techniques are time consuming, require skilled personnel to operate and are relatively expensive. [0003] In the layered object manufacturing or laser object manufacturing ("LOM") process, a CAD (computer-aided design) program is used to generate a three-dimensional image of the object and provide instructions to a computer connected to the LOM equipment, which then produces a three-dimensional solid . [0004] More specifically, LOM technology involves providing a single layer of pre-...
