Description

Three-dimensional space printing device

The present invention relates to a three-dimensional spatial printing device, and more particularly to a three-dimensional spatial printing device for thermoplastics that is suitable for material extrusion (FFF) to produce exactly the same pattern as the input image.

3D printing is a kind of rapid prototyping technology. It is based on a digital model file. The sections are printed layer by layer with liquid, powder or sheet material, and then the layers are cross-sectioned. Bonded in various ways to create an entity. This technology is characterized in that it can produce almost any shape of the item. In the past, it was often used in the manufacture of molds in the fields of mold manufacturing and industrial design, and is now being used for the direct manufacture of some products. In particular, some high-value applications (such as hip joints or teeth, or some aircraft components) already have components printed using this technology, which means that the three-dimensional space printing technology is popular.

3D printing is usually done using a digital technical material printer. First, through computer-aided design (CAD) or computer animation modeling software modeling, the 3D model is "segmented" into a layer-by-layer section to guide The printer prints layer by layer. There are many different technologies now, which differ in that they are built in different layers and in different layers. Some techniques use the method of melting or softening plastic materials to produce printed "inks" such as selective laser sintering (SLS) and fused deposition modeling (FDM), as well as some techniques. Liquid materials are used as the "ink" for printing, such as stereolithography (SLA) and laminated object manufacturing (LOM). Each of these technologies has its own advantages and disadvantages, so some companies offer a variety of printers to choose from. In general, the main consideration is the speed of printing. Degrees and costs, the price of 3D printers, the cost of object prototypes, and the choice of materials and colors and costs. The output and sales volume of 3D printers have been greatly increased since the 21st century, so some organizations and companies are working hard to develop affordable 3D printers for the average family, so that their prices are declining year by year. .

One of the most commonly used and inexpensive 3D printing techniques is the Replica Rapid Prototype Generator (RepRap), which uses a material extrusion method (FFF). One of the main benefits is that it produces the same thermoplastic properties as the input image. Plastic, this type of 3D printing equipment uses FDM (Fused Deposition Modeling), a strip hot melt forming technology, which is almost the only one that does not use lasers to fuse raw materials, but uses hot melt adhesives. The device of the tip of the gun is used to melt the strip and then move the paving material, so the materials and equipment are very cheap, and the most potential for parity.

The carrier of the above 3D printer is for forming a thermoplastic material thereon, and is usually also made of a thermoplastic material. However, in the 3D model production, it takes a long time to make a certain height, and when the bottom is made to a certain height, the bottom is solidified and the 3D model is dumped. After the above missing, a metal support is further developed under the bearing of the thermoplastic to continuously heat the carrier to prevent the bottom of the 3D model from solidifying. However, the continuous heating of the metal support seat is easy to cause the liquefaction of the thermoplastic, and the 3D model can be produced in a short time without causing too much influence. If the 3D model is too high in height, too large in size or too complicated in shape, the 3D model will be elongated. Time, while the bottom of the 3D model is liquefied and dumped. After the 3D model is completed, the 3D model needs to be cooled and solidified on the carrier, and the next 3D model cannot be produced immediately, which is disadvantageous for mass production of the 3D model. The above 3D printer needs to make a 3D model in a flat working environment. When the environment does not allow it, it usually limits the use of the 3D printer. Therefore, how to solve the above problems has always been the solution and improvement of the industry that is urgently needed to be solved.
