3D printing, also known as additive manufacturing, is a process of making three dimensional solid objects from a digital file by successively layering material. This process allows creation of complex shapes that are not possible through traditional manufacturing methods. Common polymers like thermoplastics have enabled 3D printing technology to become widely used in industries like aerospace, automotive, medical and consumer products.

Thermoplastics Dominate the 3D Printing Space

Thermoplastic polymers like acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polylactic acid (PLA) and nylon are commonly used in most desktop 3D printers as they can be repeatedly softened on heating and hardened on cooling without any change in properties. Some key advantages of thermoplastics for 3D printing include ability to melt and solidify easily for layer by layer deposition, heat resistance up to certain temperature without any chemical changes, wide availability and affordable costs. ABS is still one of the most versatile polymers for 3D printing due to its high strength, toughness and temperature resistance up to 80 degree Celsius.

Specialized Polymers Push the Boundaries

While thermoplastics dominate the desktop 3D printing segment, specialized polymers are pushing the boundaries of what can be created through additive manufacturing. Photopolymers cured by ultraviolet light are enabling high resolution 3D printing for applications requiring ultra-fine details. Photo polymers like acrylate monomers and oligomers get solidified layer by layer upon exposure to UV light and can create micron level resolution parts. They are ideal for manufacturing molds, prototypes and specialized optical components in industries like semiconductor, aerospace and healthcare.

Thermosets - The High Performance Choice

Thermosetting polymers like epoxy, polyurethane and phenolic resin exhibit properties like high heat resistance, strength and chemical resistance making them suitable for high performance applications. They undergo an irreversible curing process when heated, allowing Polymers for Additive Manufacturing to retain their shape in high temperature environments. Epoxy based photopolymers are used in high temperature 3D printing to manufacture turbine blades, rockets engine parts operating at over 300 degree Celsius. Polyurethane resins find applications as casting materials for prototypes or final parts requiring impact resistance.

Multimaterial 3D Printing Opens New Designs

Advances in multimaterial 3D printing allow combining two or more polymers with different properties into the same printed part. This enables creating objects with varied materials assembled as one like nylon reinforced with carbon fiber. Such polymers with dissimilar properties printed together allow new lightweight, durable and functional designs impossible to make before. Aero engines use polyetherimide reinforced with carbon fiber for parts needing stiffness and high heat resistance. Printed electronics is another emerging area, where conductive materials like conductive inks are combined with insulating polymers to print smart sensors and circuits.

Biopolymers Aid Sustainable Manufacturing

New generation biodegradable and bio-derived polymers are making additive manufacturing more eco-friendly and sustainable. Polylactic acid (PLA) made from corn starch is a widely used bioplastic for 3D printing. PHA (polyhydroxyalkanoate) derived from bacteria, shows properties almost similar to polypropylene but is completely biodegradable. Researchers are also exploring ways to 3D print using agricultural waste like wheat straw and natural fibers to reduce carbon footprint. Biopolymers not only provide sustainability but some like polyhydroxybutyrate have strength and toughness comparable to oil based polymers. Their applications include disposable food packaging, medical implants and consumer goods.

Future Outlook for Polymer 3D Printing

Rapid advances in 3D printing technologies along with new generation of performance polymers is expanding the applications beyond prototypes into end use production parts. Polymers for Additive Manufacturing promises to further customize design and manufacture with new materials. One key factor enabling this change will be continuous reduction in 3D printing costs through cheaper materials, printers capable of mass production, and combining 3D printing with other manufacturing techniques. Areas like electronics, biomedical and aerospace are at the forefront of transitioning from prototyping to mass production of polymeric parts through additive methods. With continuous material development and capabilities enhancement, polymer 3D printing has the potential to revolutionize industries in the coming years.
