A Complete Guide to HDPE Filaments

Thanks to their light and compact structure, HDPE filaments are used across various industries. If you are curious about the features and benefits of 3D printing with HDPE, here’s a quick guide to help you use them for your next project.

What are HDPE Filaments?

HDPE is high-density polyethylene that is sustainable and has non-absorbent properties. As a thermoplastic polymer, it has a high strength to density ratio. These properties make them ideal for various industrial applications. Whether you are a beginner or a professional, printing with HDPE offers excellent features to suit your application.

Features of HDPE Filaments!

  • Water-tightness: HDPE natural is not soluble in water. They are ideal for applications that require water tightness.
  • Lightweight and Flexible: The composition of the material keeps it from splitting at a molecular level. This makes them lightweight and flexible. As a 3D printing material, it offers excellent support for intricate designs.
  • Recyclable: HDPE is easy to recyclable and weatherproof. You can use them to make items that can outlast sun exposure and changing weather conditions.
  • FDA Approved: The material is FDA approved. That means it is non-toxic and food safe. You can use them in the medical and food industry.

What Can You 3D Print With HDPE?

Printing with HDPE filaments is beneficial for applications where strength and versatility are a priority. Below are some widely used applications of the material:

  • Waterproof Objects

Since it can stay afloat on water, HDPE natural has found usage in the pipes and tube industry for rapid prototyping. You can also use them to print objects that can retain buoyancy and do not sink.

  • Consumer Goods

Milk jugs, coasters, bottles, chairs, and many other consumer products use HDPE natural because they are sustainable and bio-degradable. They are chemical resistant and lightweight that makes them compatible with liquids and other materials.

  • Medical-Objects

Strength and chemical resistance make HDPE filaments an excellent choice for the evolving medical and healthcare industry. The material is FDA approved and helps in 3D printing innovative medical objects. Experts also use them in the prosthetics industry.

How to Start 3D Printing with HDPE?

If you are looking to start 3D printing with HDPE, you can do that with a standard FDM process. Any 3D printer compatible with ABS filament will fit the needs of HDPE filament. Here are some tips to start your 3D printing process:

  • Set the Right Extruder Temperature: You can set the HDPE filament extruder temperature between 230 and 260°C, and keep it adjusting accordingly.
  • Get a Heating Bed: To prevent self-adhesion and shrinkage issues, you can get a heating bed. This will help to keep the material stable and warm.
  • Include a Base Layer: A base layer or adhesion tools such as raft or brim will improve sticking and ensure a better finish. You can adjust the slicer setting, such as the nozzle height and others for an even print.
