3D printing – A case of polymers

kurarayus December 7, 2021

Through its exclusive manufacturing technology, 3D Printing allows us to create a variety of items. But the main advantage of 3D printing is dependent on the printing materials. Only by developing new materials will the applications of 3D printing be increased. 3D printing materials mainly consist of photosensitive materials, rubber material metal products, as well as ceramic products. Additionally, you can make use of food products like pigmented plaster materials as well as synthetic bone meal biological products that are mobile and sugar in 3D printing.

What kind of polymer product can be used for 3D printing?

Plastics for design

Design plastics refer to industrial plastics that are used for industrial components or material for real estate. They are characterized by strong hardness, impact resistance, heat resistance, solidity in addition to maturing resistivity. The normal temperature of contortion can exceed 90 deg C and they are able to be painted and electroplated mechanically. Design plastics are the most frequently used kind of 3D printing material. 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 are biodegradable.

Thermosetting Polymers

Thermosetting materials are made of thermosetting resins as the primary component, which is incorporated with other necessary additives. Through the crosslinking and healing process, a plastic product is created. Thermosetting plastics will soften as they are heated the very first time. When heated to a certain temperature the chemical reaction takes place and the crosslinking reaction can cause the material to solidify and also asset. This change is permanent. When it is temperatures rise it will not be softer and it will also not flow. It is and this is how the molding process is carried out. When the first home heating process, the plasticizing circulation fills the cavity with pressure, and it then stretches into a certain shape and size.

The photosensitive resin

Light-curing resin is also known as photosensitive resin is an polymer that undergoes rapid chemical and physical changes in an hour after being exposed to light and, after that the crosslinking process and treatment. Light-curing composite is widely used as a as a corrective and loading material for dental treatment. Due to its appealing color and high compressive force, it is playing an important part in the professional world of applications. It’s used to correct various dental caries and imperfections of previous teeth to produce satisfactory results.

The photosensitive substance is made of polymer monomers, as well as prepolymers. Due to its outstanding fluidity, instantaneous and rapid lighting treatment capabilities, liquid photosensitive materials have become the preferred option in 3D printing consumables that allow high-precision printing of items. Photosensitive materials have a fast healed speed and exceptional surface dry efficacy. After the moulding process, the appearance of the product is smooth and can be translucent or semi-transparent when it is frosted. The photosensitive material comes with the advantages of having low odour as well as commonly irritating ingredients, and is a perfect fit for personal computers with 3D printing equipment.

Polymer gel

Products made of polymer gels like salt alginate, carbonate, vegetable and pet adhesives peptone, as well as polyacrylic acid are used in 3D printing. At a certain temperature and the influence on initiators ( polyvinyl alcohol hydrolysis) and crosslinking members after polymerization a distinct network of polymer gel product is created.

If exposed to variations in ionic strength and temperature level, electrical area, or chemical substances in the gel also changes and is utilized to make memory products. The gel expands or shrinks and undergoes volume conversion. This is utilized to detect the presence of materials. The gel’s controllability mesh is a good source of to make clever medicine release materials.
