Comprehensive Guide to HIPS Filament: Properties, Applications, and Testing in 3D Printing
High Impact Polystyrene (HIPS) filament is increasingly popular in 3D printing due to its exceptional properties and versatility. This guide aims to provide you with an in-depth understanding of HIPS filament, covering its properties, applications, and suitable testing methods, alongside purchasing options available in China. Whether you’re a beginner or seasoned user, you’ll gain valuable insights to enhance your 3D printing projects.
Properties of HIPS Filament
-
Impact Resistance and Durability:
HIPS is known for its high impact resistance, making it suitable for functional parts that require toughness under stress.
-
Heat Resistance:
With a heat distortion temperature around 80°C to 92°C, HIPS performs well under moderate temperatures.
-
Solubility:
A standout feature of HIPS is its solubility in d-Limonene. This allows it to effectively serve as a support material for intricate designs, dissolving without damaging the primary print.
-
Surface Finish:
HIPS offers a smooth, matte finish that is easy to paint and aesthetically pleasing, ideal for aesthetic projects.
-
Lightweight:
The lightweight nature of HIPS is beneficial for applications in automotive and aerospace industries where weight reduction is crucial.
Printing Guidelines
Temperature Settings
- Extruder Temperature: 230°C to 270°C (optimal around 250°C)
- Bed Temperature: 100°C to 115°C
Printing Environment
Utilize a closed chamber or enclosure to minimize warping and ensure even cooling. A heated bed is essential to enhance adhesion.
Fan Settings
Keep the fan setting off (0%) to improve the bonding strength between HIPS and the primary material, especially when used as a support.
Ventilation
Ensure proper ventilation while printing to avoid inhaling potentially harmful emissions.
Testing Methods
Mechanical Testing
Conduct tests for tensile strength, flexural strength, and impact resistance. Example metrics: HIPS has a tensile strength of approximately 27 MPa and an IZOD impact strength of around 11 kJ/m².
Solubility Testing
Test a small HIPS sample by submerging it in d-Limonene to confirm complete dissolution without residue, ensuring it will perform well as a support material.
Applications of HIPS
Using HIPS as a Support Material
HIPS can be effectively used as a support for more complex prints, particularly in combinations with other materials like ABS, due to its unique solubility properties. This allows for easy removal of supports without damaging the model.

Additional Considerations
Post-Processing
HIPS benefits from chemical smoothing with d-Limonene, achieving a glossy finish. This can be done via brushing or submerging parts in a d-Limonene bath.
Safety Precautions
Maintain excellent ventilation and consider using an enclosure and active air filtration to mitigate any printing risks associated with HIPS filament.
Conclusion
By understanding the properties and appropriate use of HIPS filament, as well as the practical considerations for printing and purchasing, you can effectively incorporate HIPS into your 3D printing projects.
