What is a 3d printer?
How does a d printer work?
In this chapter, we try to provide you with a comprehensive and complete information for your loved ones in order to familiarize you with the capabilities of the three-dimensional printer operating system. Considering the progress of this industry and its application in all industries hope the following items can be a way for your loved ones to do business.
3d printers today have a special and inevitable place in advanced and industrialized countries.
Reducing costs, shortening production time, making super-complicated components, simplifying the production phase, producing different materials, owning a design and manufacturing process, and fixing bugs with multiple printers and reaching the most ideal output …
Among the features they provide a 3d printer to their users.
Three-dimensional printers are divided into different types according to their production process and consumables, and we will continue to introduce the most widely used ones.
Three-dimensional printers working
FDM technology
fused deposition modeling
Not all 3d printers use the same technology to make the product. There are several ways to do this. The major difference between these technologies is in the method of making layers used to create the final product. In this method, melting agents are used to produce layers.
The three-dimensional printer’s working style is that it has three free-movement axes in motion along the length, width, and height axis. As shown in the figure below, three-dimensional printers first melt the consumables and then through The nozzle itself is molded strand together and connects to each other and forms the desired design from the base and steps up to the z-axis, or the height of the machine, until the print is complete.
The precision of motion of the engines and the ability to place the nozzle at the desired location is a parameter that determines the precision of the 3d printer devices that valuable printers that are capable of producing precise parts use stepper motors that are more precise, which is one of the factors creating a wide range of prices In printers.
As explained, several factors contribute to the production of a piece by a 3d printer, another of its most important is the output of the nozzle, which is used in existing printers in the market, most of which are nozzles with an output of 0.4mm in diameter, which in Printers are more accurate than the more precise nozzles with outputs of 0.3-3.0mm. Also, the zmorph printer, which has been recognized by the company after extensive surveys to meet the needs of today’s Iranian industry and production, supports zero nozzles. 2. It has the ability to produce parts with high precision and level.
SLA technology
Stereolithography
Three-dimensional printers working
This technology (SLA) also uses a liquid (resin) to produce a solid portion. In this technology, ultraviolet ray and ultraviolet ray radiation are used to make body layers. In this technology, a beam of UV light is sprayed into the resin by a mirror to form the volume.
The formlabs printer is a familiar name in the 3D printer industry, which has been featured in the SLA 3d printer category in the United States and Europe. This resin printer was the world’s most resin resin printer in 2015, and has met the needs of its users. To take it.
The vast field of activity of this 3D printer in industry, electronics, precision prototyping, medicine, dentistry, architecture, and replication, gold making has allowed the super-printer to produce pieces of unbelievable precision and elegance.
Consumables This three-dimensional printer is a resin-like form that has unique properties and features that are used in direct casting, high-strength components, transparent parts, and so on.The processor of this laser used to make parts of the laser is that the laser is made through the precise movement of mirrors to the resin reservoir of the device and the final product is made.
SLS technology
Three-dimensional SLS printers
So far, you’ve been wondering what the future of the 3rd edition of the printer is and how much this industry will make and how much it will affect our lives. The answers to these questions need a somewhat forward looking and should be with the achievements of a three-dimensional printer. This tutorial introduces you to the efficiency and 3-d printer products and gives you an overview of the future of this product.
Three-dimensional SLS printers
The processor of this printer is incremental production, in this way, a 3d printer uses a high power supply like a laser and converts a mixture of fine metal particles such as metal, ceramic, or glass powder into a solid three-dimensional mass. he does. In this method, materials are often used in powder form. In this method, materials are determined by laser light, which are pre-determined in the software, with powder-like materials using a 3d model of the sample (eg a 3d file designed by solidwork or 3d scanning) on the surface. The layers are arranged in this technology so that they first place a layer of raw material on the surface and after solidifying and drying it with a laser, Next layers of material are placed on the previous layer and this process will continue until the finished piece is finished.
Raw material and application of SLS
This method can support different materials for various applications in comparison with other three-dimensional printing methods or rapid prototyping. Polymer materials such as metals can be used as raw material for printing by this technology, the samples made with this alloy have high strength and in some cases these components can be used as final and removable parts. Consumed.
In general, SLS technology is one of the most popular prototype production methods in various industries, as well as for the production of some consumer components, due to its high concessions in the construction of complex with complex geometries. Today, the technology is growing rapidly in the sectors and industries, especially the automotive and aircraft industries.
Perhaps the only reason why this smaller three-dimensional printer is less likely to be used by smaller workshops is the price of devices and materials, but considering that some parts designed and required in the industry are the only way to produce them because of the design, The only 3d printer is the use of this device and justifies the need for it in the industry.
