Finish print post-processing:

Once the 3D printer has finished its work, it will remove the object and then process it. For example, when printing some suspended structures, a support structure is required to complete it before printing the upper part of the suspended structure. Therefore, this part of the excess support needs to be removed and post-treated.

Second, sometimes 3D printed objects are rough (e.g., SLS metal printing) and need to be polished. Polishing methods include physical polishing and chemical polishing. Sandpaper grinding (sanding), pearlescent treatment (bead blasting) and vapor smoothing (vapor smoothing) are commonly used.

In addition, except for 3dp printing technology, which can achieve color 3dp printing, others can generally only print a single color. Sometimes the printed matter needs to be colored, such as ABS plastic, photosensitive resin.

Nylon, metal, etc., different materials require different pigments.

The materials for 3D printing are: photosensitive resin.

Composites, polymer powder materials, paraffin.

Powder materials, ceramic powder materials, fuses.

Wire materials, FDM ceramic materials, wood-plastic composites, FDM support materials.

The most commonly used materials such as photosensitive resins, pla, ABS, nylon, stainless steel, etc.

Photosensitive resin is a resin, which is composed of a polymer monomer and a prepolymer, in which a photo(ultraviolet) initiator (or photosensitizer) is added. Under the irradiation of ultraviolet light of a certain wavelength (2500 300nm), it can immediately cause polymerization reaction.

Complete the curing. Photosensitive resins are generally in liquid form, which can be used to make high-strength, high-temperature-resistant, and waterproof materials.

Ceramic materials have excellent characteristics such as high strength, high hardness, high temperature resistance, low density, good chemical stability, and corrosion resistance.

There are a wide range of applications in the automotive, biotechnology and other industries. However, due to the hard and brittle characteristics of ceramic materials, it is particularly difficult to process and form, especially complex ceramic parts need to be formed by molds. The mold processing cost is high and the development cycle is long, which is difficult to meet the needs of continuous product updates.

Extended information: 3D printing with different principles.

The materials used are different, there are many types of materials, and the materials used are different for different applications, and it is necessary to be specific to a certain principle and a certain application of 3D printing to specifically say what materials are used.

3D printing materials are generally connected to the specific process, and the selection of different materials also determines the process, which also determines the limitations brought by the process, such as dimensional accuracy, minimum details, and wall thickness, and conversely, if you know the dimensional accuracy, minimum details and wall thickness that the target finished product must achieve, you can also determine the optional 3D printing materials in turn.

Metal. To be precise, 3D printing is a technology that uses adhesives such as metal or plastic as printing materials and prints layer by layer based on digital models.

3D printing (3DP) is a type of rapid prototyping technology, which is a technology that uses adhesive materials such as powdered metal or plastic to construct objects based on digital model files.

3D printing is usually achieved by using digital technology material printers. It is often used in mold manufacturing, industrial design and other fields to make models, and then gradually used in the direct manufacturing of some products, and there are already parts printed using this technology.

The technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, GIS, civil engineering, firearms, and other fields.

History. 3D printing technology appeared in the mid-90s of the 20th century and is actually the latest rapid prototyping device utilizing technologies such as light-curing and paper lamination.

In November 2013, Austin, Texas-based 3D printing company SolidConcepts designed and manufactured a 3D printed metal pistol.

On January 14, 2019, the University of California, San Diego published in the journal Nature Medicine**, for the first time, using rapid 3D printing technology to create a spinal scaffold that mimics the structure of the central nervous system, which was implanted into the spine of rats with severe spinal cord damage after being loaded with neural stem cells, successfully helping rats recover motor function.

Fundamentals of 3D Printing Technology - Applications and Materials - Popular Science of 3D Printing Fundamentals.

For the selection of 3D printer materials, it is first necessary to understand the characteristics of 3D printers.

The characteristics of each 3D printing material are different, first consider the material characteristics of the product, and then choose the appropriate material to print in a targeted manner.

Ordinary photosensitive resin.

Let's first talk about ordinary photosensitive resin, this material has a high printing accuracy. The surface is also smooth, making it suitable for printing cosmetic parts.

However, this type of resin is generally weaker in strength, easy to break, and will turn yellow over time, so if the limb is more important for the appearance of the model parts, it is best to do the coloring treatment.

Longitudinal cubic red wax resin

Red wax resin is a resin dedicated to delicate industries such as figure jewelry, and the molding process is not easy to deform, ensuring accurate reproduction of the model. Compared with ordinary photosensitive resin, the texture of the model printed by this resin is more delicate, and there is no need for secondary processing.

However, it is undeniable that red wax resin has one disadvantage with ordinary photosensitive resins, that is, it has a smell.

In fact, there are other types of resins, such as ductile resins, which are slightly stronger than ordinary resins and are not easy to break.

TPUTPU is a colorful soft plastic material that can print parts such as wheels, shock absorbing pads, sealing rings, etc. Hardness between 80A and 95A.

The surface of the printed matter is smooth, and the parts with complex structure are seriously brushed after printing, and the surface hair is difficult to handle.

If the surface requirements are very high, it can also be done by casting, that is, the resin prototype is printed first, then wrapped with silicone, to make a mold, and finally molded with a similar casting method, the process is more complicated, the production cost is high, but the effect is good, and complex parts such as straps can be made.

ABSABS plastic is a commonly used engineering plastic, which has the characteristics of heat resistance, impact resistance, low temperature resistance, good chemical resistance and electrical properties, and stable product size.

Low temperature 93 118, still has some toughness at -40, suitable for -40 100. Suitable for structural components.
