Good Impact Resistance, Excellent Machinability, Good Dimensional Stability, Light Weight

HIPS (High Impact Polystyrene) is a versatile and widely used material in the field of 3D printing, specifically in FDM (Fused Deposition Modeling) technology. HIPS is a thermoplastic polymer known for its excellent impact resistance, dimensional stability, and ease of use.

One of the notable features of HIPS is its high impact strength, making it ideal for applications where durability and toughness are required. It can withstand mechanical stress and resist cracking or breaking, making it suitable for functional prototypes, tooling, and end-use parts.

Due to its favorable mechanical properties and ease of use, HIPS finds applications in various industries, including prototyping, model making, packaging, signage, and educational purposes. It can be easily post-processed, such as sanded, painted, or glued, making it a popular choice for both functional and aesthetic parts in the FDM 3D printing process.


  • Prototyping:

    HIPS is widely used for rapid prototyping due to its affordability and ease of printing. It allows for quick iterations and design validation before moving to more expensive production materials.

  • Support Structures:

    HIPS is commonly used as a support material in dual-extrusion 3D printing. It is compatible with various thermoplastics, including ABS and PLA. HIPS can be easily dissolved in Limonene, providing a convenient way to remove support structures without damaging the printed part.

  • Enclosures and Casings:

    HIPS is suitable for printing enclosures and casings for electronic devices, appliances, and consumer products. It offers good impact resistance, dimensional stability, and can be post-processed with ease, such as sanding or painting.

  • Educational and Artistic Models:

    HIPS is frequently used in educational settings and for artistic purposes. Its ease of use, low cost, and availability in different colors make it ideal for creating models, sculptures, and displays.

  • Lightweight Functional Parts:

    HIPS is known for its lightweight nature, making it suitable for printing functional parts that require a balance of strength and reduced weight. It finds applications in robotics, hobbyist projects, and mechanical components.

  • Custom Packaging:

    HIPS can be used to create custom packaging solutions, such as inserts or trays, to securely hold and protect delicate items during shipping or storage.

  • Cosplay and Props:

    HIPS is a popular choice among cosplayers and prop makers due to its ease of post-processing and ability to create intricate designs. It can be sanded, painted, and finished to achieve the desired look and aesthetics.
