3D Printing – The use case of polymers

kurarayus November 3, 2021

With its unique production technology, 3D Printing allows us to produce unprecedented kinds of products. Nonetheless, the real benefit of 3D printing technology hinges on its printing materials. Only by establishing extra brand-new materials can the application fields of 3D Printing modern technology be expanded. 3D printing products mainly consist of engineering plastics, photosensitive materials, rubber materials, metal products, and ceramic products. In addition,   can also use food products such as tinted plaster materials, synthetic bone meal, mobile biological products, and sugar in 3D Printing.

What type of polymer products can be made use of in 3D Printing?

Design plastics

Design plastics describe industrial plastics used as industrial parts or real estate materials. They have the advantages of high toughness, influence resistance, warmth resistance, high solidity, and maturing resistance. The regular contortion temperature level can go beyond 90 ° C, and they can be repainted and electroplated mechanically. Design plastics are presently the most extensively used type of 3D printing product. Acrylonitrile-butadiene-styrene copolymer (ABDOMINAL), polyamide (PA), polycarbonate (PC), polyphenylsulfone (PPSF), as well as Polyetheretherketone (PEEK) and pvoh resin are the most typically seen ones.

Bioplastics

3D printing bioplastics mainly include polylactic acid (PLA, CAS 26023-30-3), polyethylene terephthalate-1,4- cyclohexanedimethanol (PETG), poly-hydroxybutyrate (PHB), as well as Poly-hydroxy valerate (PHBV), polybutanediol succinate (PBS), polycaprolactone (PCL), and so on. All have good biodegradability.

Thermosetting polymers

Thermosetting plastics are made from thermosetting resin as the significant part, integrated with different required additives. With the crosslinking and healing procedure, a plastic item is developed. Thermosetting plastics can soften and move when heated for the first time. When heated to a specific temperature, a chemical reaction happens, and crosslinking reaction will solidify as well asset. This adjustment is permanent. After that, when heated up again, it can no more soften and also flow. It is precise with this characteristic that the moulding procedure is executed. During the initial home heating, the plasticizing circulation fills the cavity under pressure and then strengthens it into a specific size and shape item.

Photosensitive resin

Light-curing resin, likewise known as photosensitive resin, is an oligomer that can quickly undergo physical and chemical changes within a short period after being irradiated by light, and after that, crosslink and treatment. Light-curing composite material is currently a generally utilized loading and corrective product in dental care. As a result of its attractive colour and specific compressive strength, it plays an essential role in professional applications. It is utilized to fix numerous defects and dental caries of former teeth to achieve acceptable outcomes.

The photosensitive material is made up of polymer monomers as well as prepolymers. Because of its excellent fluid fluidity and instantaneous light treating attributes, liquid photosensitive material has become the first choice for 3D printing consumables for high-precision item printing. The photosensitive material has quickly healed speed and outstanding surface dry efficiency. After moulding, the look of the item is smooth, and it can be transparent or semi-transparent in a frosted state. The photosensitive material has the attributes of low odour and common bothersome ingredients, which is exceptionally ideal for personal desktop computer 3D printing systems.

Polymer gel

Polymer gel products such as salt alginate, cellulose, pet and veggie adhesives, peptone, and polyacrylic acid are used for 3D Printing. Under a particular temperature and under the action of initiators (polyvinyl alcohol hydrolysis) and crosslinking representatives after polymerization, a unique network polymer gel product is developed.

When subjected to changes in ionic strength, temperature level, electric area, and chemical materials, the quantity of the gel will likewise transform accordingly, which is used to form memory products. The gel swells or shrinks and goes through volume conversion, which is used for noticing materials. The controllability of the gel mesh can be made use of for clever medicine release materials.
