What are the technologies of polymer 3D printers?

Polymer 3D printers refer to machines and equipment that use polymer materials for 3D printing. Common polymer 3D printer technologies include HSS, MJF, SLS, etc.

Vigate Voxeljetis a 3D printer manufacturer, mainly providing:HSS printing technology。HSS (High-Speed Sintering) is a high-speed sintering technology that can sinter powders into parts in a short time. Compared with other printing technologies, HSS has a higher printing speed and higher production efficiency.

At the same time, HSS technology can achieve high printing accuracy and surface quality, which is suitable for manufacturing high-stiffness and high-precision parts.

For parts that need to be minimized under force or non-uniform temperatures, HSS technology is the best choice. Parts with HSS technology have high mechanical strength and low deformation rates, so they can be used in applications that require a high degree of reliability and precision. For many series production applications, repeatability is critical to ensure product reliability and meet certain end quality goals, and HSS technology is one of those that enables this repeatability.

First of all, a certain mechanical foundation is required, after all, the design is the transmission system and the overall structure, and the second is the circuit and control, because various electronic components are needed.

1. Engineering plastics: It is the most widely used 3D printing material.

2. Photosensitive resin: composed of polymer monomer and prepolymer.

3. Rubber materials: suitable for applications that require non-slip or soft surfaces.

4. Jin Zezheng is a material potato staring: such as high purity, good sphericity, narrow particle size distribution, and low oxygen content.

5. Ceramic material: it has excellent characteristics such as high strength, high hardness, high temperature resistance, low density, good chemical stability and corrosion resistance.

6. In addition to the 3D printing materials introduced above, there are also colored gypsum materials, artificial bone meal, cell biological raw materials and sugar and other materials currently used.

According to different modes, there are various materials, all kinds of rubber powder, light setting resin, metal and rubber powder mixture, ceramic rubber powder mixture, ABS hot fuse, thin sheet material, etc., theoretically as long as the substance can react with the laser, all powders can be.

Common materials for 3D printing include nylon glass fiber, durable nylon material, gypsum material, aluminum material, titanium alloy, stainless steel, silver plating, gold plating, and rubber materials.

There are many different technologies for 3D printing. They differ in creating parts in the way of available materials and in different layers.

The design process of 3D printing is to first model through computer modeling software, and then "partition" the completed 3D model into layer-by-layer sections, that is, slices, so as to guide the printer to print layer by layer.

Now there are dozens of different materials! Titanium alloy, cemented carbide, aluminum and other metals, as well as more than a dozen composite materials with nylon as the base material, carbon fiber can be added to nylon, etc., and others are plastic, wax, etc.

3D bioprinters are based on existing inventions that are currently being used to make 3D models of industrial parts. The difference with a bioprinter is that instead of using layers of plastic, layers of biological building blocks are used to create real living tissue. The technology is still in its infancy, but the first prototype of a 3D bioprinter was built and tested at the end of 2009.

3D bioprinters have two print heads, one for up to 80,000 human cells, called "bioink"; The other is printable "bio-paper". The so-called biopaper is actually a gel with water as the main ingredient, which can be used as a scaffold for cell growth. 3D bioprinters use cells from the patient's own body, so there is no rejection.

Introduction to 3D printing materials:

ABS: Acrylonitrile-Butadiene-Styrene, is the most popular 3D printing material because it is easy to print and tough. ABS is a durable plastic that can be used to make utility items, 3D printed parts, or prototype printing.

PLA: Polylactic acid (PLA) is a thermoplastic aliphatic polyester, also known as polylactide, polylactic acid products can be dissolved in some ways after discarding, so polylactic acid is considered to be a green plastic with good performance. PLA is one of the most commonly used materials for 3D printing, and is ideal for printing large models due to its economy and ease of use, without warping.

Plus PLA is a plant-based renewable energy source. PLA is the minimum number of deformations and shrinkage, and is best suited for objects that require a flat surface and sharp angles. PLA is brittle compared to ABS, but is still considered very robust and ideal for most household applications.

HIPS: High-impact polystyrene (HIPS) is a widely used 3D printing material that is inexpensive in cost compared to other materials. HIPS is a relatively easy material to print, similar to ABS in that it is relatively tough and can also be sanded.

HIPS is non-warped and easy to print, making it ideal for paintings, popular ornaments, models, and statues. In addition, the low cost of HIPS makes it an attractive material for printing, early testing of building models, and educational environments. HIPS is also a good support material.

It can be used with other materials when you can print with interior spaces, intricate parts and protruding parts.

Ninjaflex: Ninjaflex or TPE (Thermoplastic Elastomer) is an astounding combination of low-temperature performance, abrasion resistance, flexibility and flexibility. Simply put, it's the longest pulling material we've ever tested.

The interesting feature of NinjaFlex is that it is very supportive of materials to ABS. Ninjaflex is an elastic plastic that comes in a variety of colors. The strength of elongated yarn, combined with ABS, makes it ideal for robotic, laboratory, mechanical and wear-resistant functions.
