HIPS Filament can be useful when your 3D printing project involves shapes that are difficult to print without additional support. Imagine designing a mechanical component with an internal opening, a miniature architectural model with overhanging sections, or a prototype with details that are difficult to reach after printing.
These designs may look perfect on your computer screen. But once the printer starts building them layer by layer, things can become more complicated.
An FDM printer cannot reliably deposit material in mid-air without sufficient support beneath it. Overhangs, bridges and enclosed sections may need temporary structures to prevent the material from sagging or collapsing.
That’s where HIPS becomes interesting.
Unlike ordinary support structures that must be pulled or cut away, HIPS can be used as a separate support material and removed using compatible methods, including suitable solvents.
However, successful printing depends on the printer setup, the model material and the removal process.
Let’s look at what makes HIPS useful, where it works best and how to use it for more challenging 3D printing projects.
What Is HIPS Filament in 3D Printing?
HIPS stands for High Impact Polystyrene.
It is a thermoplastic material with properties that make it useful for certain functional prints and support structures.
In FDM 3D printing, HIPS is supplied as filament wound around a spool. The printer feeds the material through a heated hotend, where it melts and is deposited through the nozzle.
What makes HIPS particularly interesting is its ability to dissolve in suitable solvents such as d-limonene.
This means it can be used as a temporary support material for certain multi-material 3D printing applications.
Instead of forcing a tool into a narrow opening to remove supports, the user can sometimes dissolve or loosen the HIPS material after printing.
HIPS is also used for lightweight models, prototypes and selected functional objects.
However, it isn’t automatically suitable for every printer or material combination.
Before using HIPS Filament, it’s important to understand its printing requirements and compatibility with the main material.
Why HIPS Filament Is Useful for Support Structures
Support structures are temporary features that hold up parts of a model while it’s being printed.
For example, imagine printing a small arch.
The two vertical sides may print without much difficulty, but the upper section needs enough support to prevent the freshly deposited plastic from sagging.
A slicer can generate supports below these areas.
If the supports are printed using the same material as the model, they often need to be removed manually.
This can work well for simple shapes. But complex internal cavities, narrow gaps and delicate features may be difficult to access.
HIPS provides another option.
When used with a compatible main material and a printer capable of handling multiple materials, HIPS can create temporary structures that support the model during printing.
Afterward, the supports can be removed mechanically or, where suitable, by using a compatible solvent.
This approach may reduce the need to pull supports from difficult areas.
It doesn’t guarantee a perfect finish, but it can make certain designs easier to produce.
7 Best Uses of HIPS Filament for Complex 3D Prints
HIPS Filament can be useful for more than ordinary support structures.
Here are seven applications worth exploring.
1. Support Structures for Complex Mechanical Parts
Mechanical components often contain holes, recesses and overhanging surfaces.
These features can become difficult to print, particularly when they face downward or have limited space beneath them.
HIPS can be used as a separate support material to hold these sections during printing.
Consider a prototype housing with a recessed mounting area.
Temporary support may help maintain the geometry until the print is complete.
Once the part has cooled, the HIPS support can be removed using an appropriate method.
Compatibility between the support and main material should always be tested before printing a large or important component.
2. Architectural Models With Detailed Overhangs
Architectural models sometimes include balconies, roof projections, arches and other complex features.
These designs can be challenging because small details may require support during printing.
HIPS Filament may help create temporary structures beneath selected features.
For example, a miniature building with a projecting balcony may need support below the overhang.
Using a suitable separate support material can make removal more manageable, particularly when the surrounding details are delicate.
However, the quality of the final surface still depends on support placement, print orientation and slicer settings.
3. Prototypes With Internal Cavities
One of the more difficult 3D printing challenges involves models with enclosed or partially enclosed spaces.
Imagine printing a component with a curved internal passage.
Traditional supports may become trapped inside the object, making mechanical removal difficult or impossible.
Dissolvable supports can sometimes offer an alternative.
If the design allows solvent to reach and remove the support material, HIPS may help with certain internal geometries.
The main material must also be compatible with the solvent.
Fully enclosed cavities without access for solvent circulation may remain unsuitable, so the design should be evaluated before printing.
4. Functional Product Development Models
Product designers frequently create prototypes to check dimensions, component placement and assembly.
Some designs include snap-fit features, mounting points or complex surfaces that are difficult to print without support.
HIPS can help support selected areas while the model is being produced.
For example, a device enclosure with internal ribs and recessed sections may benefit from carefully positioned supports.
This makes HIPS Filament worth exploring in product development workflows where complex geometry is involved.
The main advantage is greater flexibility in planning support removal, not automatically stronger finished parts.
5. Detailed Miniatures and Artistic Models
Miniature sculptures and decorative models often contain thin projections, curved features and difficult overhangs.
Removing ordinary supports from these areas can sometimes damage the model.
A compatible dissolvable support material may reduce the amount of manual work needed around fragile features.
Imagine printing a decorative model with a raised arm or an intricate architectural ornament.
HIPS support structures may provide temporary support during the printing process.
However, small details and surface quality depend on the main filament, printer precision and support interface settings.
6. Lightweight Demonstration Models
HIPS can also be used as a model material in its own right.
It is relatively lightweight and can be suitable for selected demonstration parts, concept models and prototypes.
For students and engineering learners, printing with HIPS provides an opportunity to understand material behavior and high-temperature FDM printing.
You could use it to make a sample enclosure, a basic geometric model or a component for checking design fit.
Unlike a support structure, the HIPS remains part of the final object in these applications.
Keep the material’s mechanical and temperature limitations in mind before using it for demanding functional parts.
7. Multi-Material 3D Printing Projects
Multi-material printing allows users to combine different filaments within one project.
One material can form the main object, while another provides temporary support.
HIPS Filament is a candidate for certain dual-material and tool-changing setups.
For example, a printer may use one extruder for the main material and another for HIPS supports.
The slicer must be configured to assign each material correctly.
The printer also needs suitable extrusion temperatures, bed conditions and a way to manage material changes.
This workflow can be useful, but it is more demanding than ordinary single-material printing.
HIPS Filament and ABS: What You Should Know
HIPS is often discussed alongside ABS because the two materials have broadly similar printing temperature requirements.
Some HIPS formulations are used as breakaway supports for ABS, which can be useful when the interface between the materials allows controlled removal.
However, there’s an important distinction between breakaway and dissolvable supports.
HIPS can dissolve in d-limonene, but some ABS and ASA formulations can also be affected by that solvent.
This means you shouldn’t assume an ABS model will remain completely unchanged during the support-removal process.
Before using a dissolvable support workflow, test a small sample of the main material and HIPS together.
For technical guidance, the Prusa Research HIPS Material Guide explains HIPS properties, dissolution and compatibility considerations.
For ABS combinations, the UltiMaker Marketplace’s Ultrafuse HiPS description also describes its use as a breakaway support material.
Choosing the right removal method is just as important as printing the support successfully.
How to Print HIPS Filament Successfully
Printing HIPS requires suitable hardware and a controlled printing setup.
It generally needs higher temperatures than ordinary PLA.
The exact settings depend on the filament formulation and printer.
Start With the Manufacturer’s Temperature Recommendations
For reference, HIPS is commonly printed with nozzle temperatures around 225–255°C and heated-bed temperatures around 100–110°C.
These aren’t universal values.
NFIL3D publishes HIPS printing guidance and technical information on its Get Started page.
Its listed HIPS nozzle-temperature starting point is 220°C, so users should follow the specific NFIL3D product guidance rather than automatically copying another manufacturer’s profile.
A temperature tower can help determine suitable extrusion settings for your printer.
Use a Suitable Heated Bed
A heated print bed helps improve adhesion and reduce temperature-related printing problems.
HIPS can shrink as it cools, so a stable printing environment is important.
For larger models, an enclosure may help reduce sudden temperature changes and warping.
Choose the Right Support Settings
Support density, interface settings and placement affect how well HIPS supports a model.
A support structure that’s too sparse may not provide enough stability.
Too much support can increase material consumption and make post-processing more difficult.
Start with a suitable slicer profile and test the configuration on a small model.
Check Your Printer’s Hardware
If you’re planning to print HIPS as a separate support material, your printer needs a compatible multi-material setup.
A normal single-extruder printer can print an entire model using HIPS, but it cannot automatically print the main object in one material and HIPS supports in another without an appropriate material-changing system.
Check your hardware before planning a dual-material project.
Provide Suitable Ventilation
HIPS is a heated thermoplastic and can release fumes and airborne particles during printing.
Use appropriate ventilation and exposure controls according to your printer and filament manufacturer’s safety instructions.
Avoid operating high-temperature filament printers in poorly ventilated occupied rooms.
How Are HIPS Support Structures Removed?
HIPS supports can sometimes be removed mechanically, depending on how they were printed and how they bond to the main model.
For suitable multi-material combinations, d-limonene may be used to dissolve or loosen HIPS.
However, d-limonene is not the same as water.
It is a chemical solvent that requires appropriate handling, ventilation, protective equipment and disposal.
The model material may also be affected by prolonged solvent exposure.
Never assume that the finished part is solvent-resistant without testing.
For complex or valuable prints, begin with a small compatibility sample.
Use the solvent manufacturer’s safety data sheet and follow the filament supplier’s guidance.
If the main model is sensitive to d-limonene, consider a compatible breakaway support method or a different support material.
HIPS Filament vs Regular Support Materials
Traditional supports and specialty support filaments both have advantages.
| Feature | Same-Material Supports | HIPS Support Filament |
|---|---|---|
| Printer requirements | Usually single extruder | Typically multi-material setup |
| Removal | Usually manual | Breakaway or compatible solvent |
| Complex cavities | Removal can be difficult | May help if supports are accessible |
| Material changes | Not required | Required for separate support material |
| Setup complexity | Generally simpler | More advanced |
| Post-processing | Mechanical removal | Depends on removal method |
For simple models, traditional supports are often the easiest choice.
HIPS becomes more interesting when the model’s geometry or removal requirements justify a separate support material.
If you’re new to support printing, it’s worth learning ordinary slicer support settings before experimenting with dissolvable materials.
Common HIPS Filament Printing Problems
HIPS printing can be challenging, particularly when moving from PLA.
Warping
As HIPS cools, contraction can create internal stresses. Suitable bed temperature, surface preparation and a stable environment can help.
Poor Bed Adhesion
If the first layer doesn’t stick properly, the print may detach. Check the print surface and first-layer settings.
Support Separation
When using different materials, the support may not adhere sufficiently during printing. Review support interface settings and material compatibility.
Difficult Support Removal
A support material isn’t automatically easy to remove. Solvent access, model geometry and compatibility all matter.
Inconsistent Extrusion
Incorrect temperature, excessive printing speed or material-feeding issues may cause gaps or rough surfaces.
If you’re experimenting with HIPS Filament for the first time, change one setting at a time and compare the results.

Practical Tips Before Your First HIPS Print
If you haven’t worked with HIPS before, start with a simple model.
First, print a small HIPS test object to check extrusion temperature, bed adhesion and dimensional quality.
Once you’re familiar with the material, try a small multi-material project if your printer supports it.
Avoid starting with a large design containing complicated internal structures.
A small test can reveal whether the materials adhere correctly during printing and whether the planned support-removal method works as expected.
Keep notes on the temperatures, support interface settings and removal methods that produce good results.
These details can save time when you attempt more complex models.
Final Thoughts
HIPS Filament can make certain complex 3D printing projects easier to manage by providing temporary support for difficult shapes.
It is particularly interesting for users working with overhangs, internal cavities, product prototypes and multi-material printing.
Its ability to be removed mechanically or dissolved under suitable conditions gives designers another option when ordinary support structures are difficult to remove.
However, using HIPS successfully requires attention to printing temperatures, material compatibility, support settings and solvent safety.
Not every project needs a specialty support filament.
For simple models, ordinary supports may be sufficient. For more complex designs, HIPS can be worth exploring when the printer and material combination are suitable.
