Serving the UK & IE plastics industry


3D printing, also known as additive manufacturing, is a process that uses a digital model as a guide to production. A computer-controlled machine reads the digital model and builds the part layer by layer using plastics in 3D printing.

3D printing is a highly adaptable process that enables manufacturers to create parts in various sizes and shapes. It is especially well-suited for producing parts with complex geometries and internal features that would be difficult or impossible to manufacture using traditional manufacturing processes.

3D printing is a rapidly evolving technology used in fields such as aerospace, medicine, and automobiles. It enables manufacturers to produce parts with high accuracy and repeatability whilst being a cost-effective manufacturing process with minimal setup and tooling requirements.

One exciting aspect of 3D printing is the ability to create customised and personalised products. Manufacturers can easily modify the part's design to meet the customer's needs because the process involves building parts layer by layer using a digital model. This enables the production of customised products, which would not be possible using traditional manufacturing processes.

Another interesting aspect of 3D printing is its potential to revolutionise supply chain logistics. Because 3D printing allows for the production of parts on-demand and decentralised, it can significantly reduce the need for extensive inventory stockpiles and long lead times. This could have significant implications for industries that rely on just-in-time manufacturing and fast turnaround times.

What Plastic Materials are used for 3D Printing?

Here are some of the most common plastic materials used in 3D printing:

  • Acrylonitrile butadiene styrene (ABS): ABS is a strong, durable plastic used to make toys, automotive parts, and household appliances.
  • Polylactic acid (PLA): PLA is a biodegradable plastic that is made from renewable resources such as cornstarch or sugarcane. It is commonly used to make food packaging, medical implants, and toys.
  • Polyethylene terephthalate (PET): PET is a strong, transparent plastic used to make water bottles, food containers, and packaging materials.
  • Polypropylene (PP): PP is a lightweight, flexible plastic that is commonly used to make automotive parts, packaging materials, and medical devices.
  • Nylon: Nylon is a strong, flexible plastic that is used to make gears, hinges, and other mechanical parts.

What are the Advantages of 3D Printing?

  • On-demand production: 3D printing allows for on-demand production, reducing inventory and storage costs.
  • Healthcare: It is used in medical fields for prosthetics, implants, and custom devices, improving patient outcomes and quality of life.
  • Sustainability: Reduces transportation costs and emissions associated with product sourcing and manufacturing, leading to a smaller carbon footprint.
  • Cost-effective: 3D printing eliminates the need for expensive tooling, reducing production costs and allowing for low-volume production runs.
  • Accessibility: Makes complex shapes and geometries possible, enabling greater design freedom and creativity.

What are the Disadvantages of 3D Printing?

  • Technical skills required: operation and maintenance of the 3D printer require specialised knowledge and skills, limiting accessibility for some individuals.
  • Limited durability: lower structural integrity and wear resistance compared to traditionally manufactured products, limiting its application use.
  • Health and safety concerns: potential release of harmful particles during printing, requiring proper ventilation and air filtration.
  • Slow printing speed: longer printing times for large and complex objects, limiting its use for mass production.
  • Post-processing: requires additional steps to complete the object, such as sanding or painting, adding time and cost to the overall process.
  • Material limitations: limited selection of materials, leading to functional and aesthetic limitations and limiting its use in certain applications.
