Everything You Need to Know about Engineering 3D Printing Filaments

The engineering field is making great advancements thanks to 3D printing technology. It has made it possible to produce cheaper, stronger, and more resistant parts at a faster time frame, from months to mere days. Prototyping is also that much easier and more affordable, therefore giving engineers the confidence to keep experimenting and improving on their designs at minimal expense and time spent.

Benefits of 3D printing in engineering applications

  • 3D printing greatly reduces development time to days
  • Designs can easily be rapidly tested and revised
  • Parts can be improved upon and adjusted according to preference at a shorter timeframe
  • 3D printed parts can be produced faster and easier, regardless of the complexity of the design
  • Design can be finalised first before casting it into an expensive mold

Types of Engineering 3D Printer Filaments

When producing 3D printed parts for engineering applications, tensile strength, toughness, and durability are essential. Here are the top engineering 3D printing filaments that show superior mechanical strength and resistance.

ASA Filaments

The ASA filament (Acrylonitrile Styrene Acrylate) is one of the most popular 3D printer filaments for engineering applications due to its exemplary mechanical strength, chemical, UV, and water resistance, and dimensional stability. They are best for use for exterior signage, sporting goods, automotive exterior parts, and car exterior parts, and outdoor components.

Features:

  • High UV resistance
  • High glass transition temperature
  • Strong stress and impact resistance

Tradeoffs:

  • High extruder temperature

X3D Pro ASA

X3D Pro ASA has excellent zero-warp properties, mechanical properties and strength, and UV resistance. It is the easiest to print to with due to its strong interlayer and bed adhesion.

ApolloX

ApolloX is a high-strength and performance engineering filament made of industrial-grade modified ASA compound. It has improved thermal stability and flow behaviour. It is also claimed to display flawless first and interlayer adhesion and zero-warping properties.

Polypropylene Filaments

A diamond in the rough, the Polypropylene filament is the hardest filament to print with but if done right, it can produce unrivalled results. It is commonly used in consumer and engineering applications due to its flexibility and chemical resistance.

Features:

  • Lightweight
  • Relative flexibility
  • Good chemical resistance
  • Improved strength to weight ratio

Tradeoffs:

  • Low heat resistance
