What is 3D printing?
Every 3D printing process starts with a 3D model, which can be started by using a variety of 3D software - in the 3D CAD industry, designers and consumers accessing single programs. Simpler, more accessible, or use a 3D scanner to create a 3D model. The model is then converted into multiple layers, and is read by 3D printers in the form of program code. As mentioned, there are many different 3D printing technologies that process materials in a variety of ways, to create the final product. , metals, ceramics, powders, etc. are common materials used in modern industrial and manufacturing applications. c proceed with all kinds of different biological materials.
Different kinds of printers using different technologies to manipulate the data in other ways need to know important nhau.Dieu in 3D printing technology is no one material and technology that is " fit all okay"For example, some 3D printers use powdered materials (nylon, plastic, ceramic, metal), using a large heat source that melts the material and makes it bond together in a certain shape. Others use a laser that melts and bonds the plastic into thin layers. Another 3D printing process is the processing of plastic droplets, which makes us think of inkjet printing, but with They are more expensive than ink and use glue to bond layers together. But perhaps the most common and most recognizable printing technology is the deposition process, and this process is mostly done on The process is extruded plastic, usually PLA or ABS, in the form of microfiber through a hot spray to create layers in accordance with the design.
As we can print directly, creating complex components creates a product block that k needs to assemble.
However, another important point to emphasize is the current 3D printing technology is plug and play. There are many steps sewing before printing and when applied to the printer is often overlooked. Design process for printing. 3D in fact requires data conversion quite time consuming and complicated, especially with complex parts in the design process. However, continuous updates and software upgrades make the functions much better. Furthermore, when the printer is stopped, many components need to be improved. Aid is an indispensable process when there is additional support, but other things such as sanding, lacquering, or traditional scribing are all done manually requiring time skill and patience.
The point for any 3D printing process is a 3D digital model, which can be created using a variety of 3D software programs - in the industry this is 3D CAD, for Makers and Consumers there are simpler, more accessible programmes available - or scanned with a 3D scanner. Model is then sliced into layers, so converting the design into a file readable by the 3D printer. Thé material được xử lý bởi máy tính của 3D và được theo dõi theo thiết kế và tiến trình. As stated, there are a number of different types of 3D printing technologies, which process different materials in different ways to create final objects. Functional plastics, metals, ceramics and sand are, now, routinely used for industrial prototyping and production applications. Research is also being conducted for 3D printing of bio materials and different types of food. Generally speaking though, at the entry level of the market, materials are much more limited. Plastic is currently only widely used material - usually ABS or PLA, but there are a growing number of alternatives, including Nylon. There is also a growing number of entry level machines that have been adapted for foodstuffs, such as sugar and chocolate.
How it Works
The different types of 3D printers each employ a different technology that processes different materials in different ways. It is important to understand that one of the most basic limitations of 3D printing — in terms of materials and applications — is that there is no ‘one solution fits all’. For example some 3D printers process powdered materials (nylon, plastic, ceramic, metal), which utilize a light/heat source to sinter/melt/fuse layers of the powder together in the defined shape. Others process polymer resin materials and again utilize a light/laser to solidify the resin in ultra thin layers. Jetting of fine droplets is another 3D printing process, reminiscent of 2D inkjet printing, but with superior materials to ink and a binder to fix the layers. Perhaps the most common and easily recognized process is deposition, and this is the process employed by the majority of entry-level 3D printers. This process extrudes plastics, commonly PLA or ABS, in filament form through a heated extruder to form layers and create the predetermined shape.
Because parts can be printed directly, it is possible to produce very detailed and intricate objects, often with functionality built in and negating the need for assembly.
However, another important point to stress is that none of the 3D printing processes come as plug and play options as of today. There are many steps prior to pressing print and more once the part comes off the printer — these are often overlooked. Apart from the realities of designing for 3D printing, which can be demanding, file preparation and conversion can also prove time-consuming and complicated, particularly for parts that demand intricate supports during the build process. However there are continual updates and upgrades of software for these functions and the situation is improving. Furthermore, once off the printer, many parts will need to undergo finishing operations. Support removal is an obvious one for processes that demand support, but others include sanding, lacquer, paint or other types of traditional finishing touches, which all typically need to be done by hand and require skill and/or time and patience.
