There are many different types of plastics used in 3D printing, each with its own unique properties and applications. The most common type of plastic used in 3D printing is Acrylonitrile Butadiene Styrene (ABS), a durable, impact-resistant plastic that can be used in high temperatures. Other popular plastics include polylactic acid (PLA), a biodegradable plastic made from renewable sources, and Polyethylene terephthalate (PET), which is often used in disposable plastic bottles. The use of short fiber composites in plastics can increase stiffness and strength, and water-soluble plastics like Polyvinyl alcohol (PVA) are used to create support structures for specific parts. Polycarbonate (PC) is also a strong and durable plastic with a high glass transition temperature, making it suitable for high-temperature applications.

Polylactic acid (PLA) is a popular eco-friendly, biodegradable plastic made from renewable sources
Polylactic acid, or PLA, is a popular eco-friendly, biodegradable plastic made from renewable sources. It is a bioplastic made from renewable plant-based materials like corn, cassava, sugarcane, or sugar beet pulp. The process of creating PLA involves the fermentation of starch or sugar extracted from these renewable resources, which results in the production of lactic acid. This lactic acid is then transformed into a monomer called lactide, and the polymerization of lactide allows for the manufacturing of PLA.
PLA is a lightweight and economical product, and it has become the most widely used filament for 3D printing due to its biodegradable nature. PLA is also used in packaging, agriculture, and biomedical industries. Its highly suitable thermal and mechanical properties make it a popular choice for manufacturers, and it is often used in combination with other materials such as carbon fiber or glass fiber to create stronger parts.
Compared to conventional plastics, PLA offers significant environmental and economic advantages. It emits three times less CO2 and does not depend on petroleum or other fossil fuels for its production. Instead, it is made from rapidly renewable plant starch, which can be sourced from agricultural produce and crop residue. This means that PLA production can make use of agricultural by-products that would otherwise be wasted.
Despite its benefits, there are some limitations to PLA. Its compostability has historically been restricted to industrial installations due to the requirement for high and constant temperatures. Additionally, its extended disintegration time previously limited its usage to producing relatively thin films with small quantities of PLA. However, ongoing research aims to further enhance the environmental impact of PLA, such as through the use of non-agricultural feedstocks and more efficient farming practices.
Overall, PLA is a popular and eco-friendly alternative to conventional plastics, offering advantages in terms of biodegradability, renewability, and reduced environmental impact.

Acrylonitrile Butadiene Styrene (ABS) is a durable, impact-resistant, and flexible plastic
Acrylonitrile Butadiene Styrene (ABS) is a widely used thermoplastic polymer. It is a popular engineering plastic and 3D printing filament type. ABS is known for its durability, impact resistance, and flexibility.
ABS is derived from the combination of acrylonitrile, butadiene, and styrene. Acrylonitrile provides chemical and thermal stability, butadiene adds toughness and strength, and styrene gives the finished polymer a glossy finish. The different amounts of each monomer can be varied to create different finished products.
ABS has a low melting point, which makes it suitable for injection moulding and 3D printing. It also has high tensile strength and is resistant to physical impacts and chemical corrosion. This allows the finished plastic to withstand heavy use and adverse environments. ABS is commonly used in automotive parts, consumer goods, electronics, and toys.
ABS is also lightweight and has excellent impact resistance, making it suitable for applications that require durability and toughness. It has good mechanical properties, including high strength and stiffness, and can withstand loads and stresses, making it suitable for structural components.
However, ABS has some disadvantages. Its low melting point makes it unsuitable for high-temperature applications and medical implants. It has poor solvent and fatigue resistance and is susceptible to UV exposure and weathering unless properly protected. Additionally, ABS is flammable when exposed to high temperatures and can decompose into potentially harmful constituents.

Polyethylene terephthalate (PET) is a commonly used plastic in thermoforming processes
PET is a transparent, amorphous thermoplastic when rapidly cooled, but behaves as a semicrystalline plastic when slowly cooled or cold-drawn. It can be processed using common moulding methods such as injection moulding, blown moulding, and extrusion. Thermoforming is a specific type of moulding method where a plastic sheet is heated and pressed over a mould. PET is suitable for thermoforming because it can be easily shaped and moulded into the desired form.
In addition to its use in packaging and textiles, PET is also used in engineering applications. It can be combined with other materials, such as glass fibre, to create engineering resins used in various industrial sectors. PET is also widely recycled, with the resin identification code of 1. Recycled PET can be melted down and spun into fibres for fibrefill or carpets, or it can be recycled back into its original uses.
The versatility of PET makes it a popular choice for many manufacturers. It can be easily processed and moulded into a variety of shapes and forms, making it suitable for a wide range of applications, from packaging to engineering. Its strength, durability, and heat resistance also contribute to its popularity in various industries.
Overall, PET is a commonly used plastic in thermoforming processes due to its unique properties, ease of processing, and versatility. It is an important material in the manufacturing industry, with a wide range of applications and potential for recycling and reuse.

Polyvinyl alcohol (PVA) is a water-soluble plastic used in low-end home printers
Polyvinyl alcohol (PVA), also known as PVOH or PVAl, is a water-soluble synthetic polymer. It is a plastic made from fossil fuel sources and is used in a variety of industries. PVA is colourless, odourless, and has high tensile strength and flexibility. It also has good oil, grease, and solvent resistance, as well as air impermeability and low toxicity.
In 3D printing, PVA is used to create support structures for specific parts of a product that may otherwise warp or collapse. It is not usually used to make the final product. PVA is also used in medicine, such as for cartilage replacements, contact lenses, and drug capsules. It is used in fibre production to prevent breakages and is a key component in making high-gloss paper.
PVA is commonly used in household products like sponges, dishwasher pods, and laundry detergent pods. It is also used in the production of sachets and thin layers of plastic wrapping and lining. PVA can be dissolved in water, but it does not always fully biodegrade. Studies have shown that over 65% of PVA released from wastewater treatment plants (WWTPs) ends up in waterways and soil.
PVA has medical applications due to its biocompatibility, low protein adhesion, and low toxicity. It has been used for vascular stents, cartilage replacements, contact lenses, and drug capsules. PVA-based polymers are used in additive manufacturing, such as in 3D printed oral dosage forms for the pharmaceutical industry. PVA is used as a binder substance for drug-loaded tablets with modified drug-release characteristics.
PVA is a versatile material with a wide range of applications. However, its impact on the environment as a plastic pollutant is a growing concern. More research is needed to determine the specific impacts of PVA on the environment and to develop methods for its complete biodegradation.
