HIPS Filament Guide 2026 — Settings, Use Cases & When to Choose It

HIPS (High Impact Polystyrene) is one of the most underrated materials in FDM printing. Most people have heard of it only in the context of dissolving supports for ABS, and that use case is genuinely excellent — but HIPS is also a capable standalone engineering material that prints more reliably than ABS, costs less than nylon, and offers a lightweight profile that few other filaments can match.

This guide covers everything: print settings, the d-Limonene dissolution workflow, when to use HIPS as a structural material instead of ABS, and an honest comparison against PVA for support applications. By the end, you will know exactly when HIPS earns a place in your printer and when it does not.

HIPS as Soluble Support for ABS

This is the primary reason most FDM users seek out HIPS in 2026. The concept is straightforward: HIPS and ABS print at nearly identical temperatures, so a dual-extruder printer can use ABS for the model and HIPS for support structures. Once the print is done, the entire support network dissolves in d-Limonene — a citrus-derived solvent — leaving only the ABS part, untouched and fully supported during printing.

The result is complex ABS geometry that would be impossible to clean by hand: internal channels, bridging structures, interlocking assemblies, and overhangs with zero support scarring.

Why HIPS Works Better Than PLA Supports for ABS

The problem with PLA supports on ABS parts is temperature mismatch during cooling. ABS contracts significantly as it cools; PLA does not at the same rate. This creates stress at the interface between support and model, which can cause delamination in the ABS or, more commonly, leaves support material so embedded in the overhangs that manual removal damages the surface.

HIPS avoids this entirely. It contracts at a rate close to ABS, stays dimensionally stable at the bed temperatures required for ABS (95–110°C), and releases cleanly in d-Limonene without any mechanical force.

Hardware Requirements

To use HIPS as soluble support, you need:

• A dual-extruder printer (or IDEX machine like the Bambu Lab X1E, Creality IDEX series, or Prusa XL)
• Hotend capable of reaching 230–240°C on both toolheads
• A heated bed reaching 95°C minimum
• An enclosure

Single-extruder printers cannot use HIPS as soluble support. There is no workaround for this limitation.

Dual Extruder Settings for HIPS + ABS

Parameter	ABS (Model)	HIPS (Support)
Nozzle Temp	240°C	230°C
Bed Temp	100°C	100°C (shared)
Fan Speed	Off	Off
Interface Layers	—	2–3 layers
Support Z-Gap	—	0.1–0.2 mm

Set a small Z-gap (0.1–0.2 mm) between the HIPS support and ABS surface. This ensures the solvent can penetrate and that the support does not fuse too strongly to the model. Without this gap, dissolution still works but takes longer.

HIPS as a Standalone Material

HIPS is not just a support material. When evaluated on its own merits, it is a genuinely useful engineering thermoplastic that deserves consideration over ABS in several scenarios.

Where HIPS wins over ABS:

• Weight: HIPS is slightly less dense than ABS (~1.03 g/cm³ vs ~1.04 g/cm³). On large parts, this difference is noticeable.
• Ease of printing: HIPS warps less than ABS. It still benefits from an enclosure, but failures from corner lifting are less frequent.
• Surface finish: HIPS naturally produces a matte, smooth surface that many users prefer for display models, signage, and prototypes.
• Machinability: HIPS machines and cuts cleanly. It is a common material for CNC prototyping in industry precisely because it is easy to drill, tap, and sand.

Where ABS wins over HIPS:

• Acetone smoothing: ABS can be acetone vapor-smoothed to a glossy, near-injection-molded finish. HIPS cannot.
• Higher heat resistance: ABS glass transition runs slightly higher (~105°C vs ~95°C for HIPS), which matters for parts near heat sources.
• Broader brand availability and community profiles: ABS has been optimized by far more users over a longer period.

Where PETG beats both for standalone use:

If you do not specifically need HIPS's weight advantage or its compatibility with d-Limonene dissolution, PETG is easier to print, requires no enclosure, and offers better layer adhesion. Choose HIPS as a standalone material only when you have a specific reason to — not as a default engineering filament.

Good standalone HIPS applications: lightweight RC parts, large display models and props, prototypes that need sanding and painting, dimensional mockups.

Temperature Tips

Print a temperature tower between 220°C and 240°C before committing to a full print. HIPS is sensitive to temperature: too cold and you get poor layer bonding; too hot and stringing becomes difficult to manage. The sweet spot for most brands is 228–232°C, but this varies by color and manufacturer.

D-Limonene Dissolution

This is the part of HIPS printing that looks more complicated than it is. The workflow is simple once you have the materials on hand.

What You Need

• d-Limonene: Available on Amazon, craft supply stores, and specialty chemical suppliers. Budget around $15–25 for 500 ml. Pure d-Limonene works best; avoid citrus cleaning blends with added surfactants.
• Container: A lidded glass or HDPE plastic container large enough to submerge your print. Do not use polystyrene containers — d-Limonene dissolves them.
• Gloves: Nitrile gloves. d-Limonene is derived from citrus and is low-toxicity, but repeated skin contact can cause irritation.

Step-by-Step Workflow

1. Remove the print from the bed. No need to remove supports manually.
2. Place the print in the container and cover with enough d-Limonene to fully submerge it.
3. Cover the container and leave at room temperature.
4. Check after 2–4 hours. Gently agitate the container to expose fresh solvent to the dissolving HIPS.
5. For large support volumes, replace the d-Limonene with fresh solvent after the first soak and repeat.
6. When all HIPS is dissolved, remove the ABS part and rinse under warm water.
7. Allow the part to dry fully (30–60 minutes air dry or overnight).

Dissolution Times

Support Volume	Approximate Time
Light supports (small overhangs)	1–3 hours
Medium supports (complex geometry)	3–8 hours
Heavy support structures	8–16 hours, may need solvent change

Warming the d-Limonene to 30–40°C (place the container in warm water) accelerates dissolution significantly without risking the ABS part. Do not exceed 50°C.

Safety and Disposal

d-Limonene is biodegradable and low-toxicity compared to most solvents. However:

• Work in a ventilated area. The citrus smell is pleasant but concentrated vapors can cause headaches.
• Do not pour dissolved HIPS/d-Limonene down the drain in large quantities. Let the solvent evaporate in a ventilated outdoor area and dispose of the solid residue with household waste, or contact your local waste disposal authority.
• Keep away from open flames — d-Limonene is flammable (flash point ~49°C).
• Store in a sealed container away from light and heat. Reuse the solvent until it becomes too saturated to dissolve effectively.

Troubleshooting

Warping

HIPS warps less than ABS but will still lift on large prints or cold ambient conditions.

• Increase bed temperature to 105°C
• Use a brim of at least 10 mm
• Ensure the enclosure is closed — even small drafts cause corner lifting
• Apply a thin layer of PVA glue stick or hairspray to the bed surface for extra adhesion
• Check that the first layer is slightly squished into the bed; under-extrusion on the first layer is a common warping trigger

Layer Adhesion Problems

If layers are delaminating or the print snaps easily at layer lines:

• Increase nozzle temperature by 5°C increments up to 240°C
• Turn the cooling fan completely off
• Check enclosure temperature — chamber temp below 40°C significantly hurts HIPS layer bonding
• Dry the filament (see below)

Stringing

HIPS strings more than ABS when printing temperature is too high or retraction is insufficient.

• Drop nozzle temperature by 5°C
• Increase retraction distance by 0.5 mm increments
• Increase travel speed to 180–200 mm/s
• Enable Z-hop (0.2 mm) for travel moves over gaps

Wet Filament

HIPS absorbs moisture and will crack, pop, and produce rough surfaces when wet. Dry at 65–70°C for 4–6 hours in a filament dryer or food dehydrator. Store in airtight bags with silica gel between uses. If you hear popping sounds during printing, moisture is almost certainly the cause.

Best HIPS Brands 2026

Polymaker PolySupport

The premium choice. PolySupport is specifically formulated as a support material, and it shows: diameter consistency is excellent (±0.03 mm), stringing is minimal compared to generic HIPS, and it dissolves cleanly in d-Limonene without leaving residue on ABS surfaces. It comes at a price — around $30–35/kg versus $20–25 for budget brands — but for serious dual-extruder work, the consistency justifies the cost.

Best for: Professional use, dual-extruder support applications, when print quality and reliability matter.

eSun HIPS

The reliable mid-tier option. eSun is one of the most widely used filament brands in the community, and their HIPS is consistent and well-calibrated. It prints cleanly at 230°C and bed 100°C with minimal tuning required. Occasionally produces more stringing than PolySupport, but a small temperature drop usually fixes it. At $22–27/kg, it offers good value.

Best for: General use, standalone HIPS parts, budget-conscious dual-extruder setups.

Hatchbox HIPS

Widely available on Amazon and delivers consistent results for the price. Hatchbox's quality control is solid for a budget brand. The filament tends to run slightly hotter than labeled — start at 235°C and dial back if needed. Good for first-time HIPS users who want availability and reasonable quality without premium pricing.

Best for: Beginners, standalone HIPS parts, users who value fast shipping and easy returns.

HIPS vs PVA Support Material

The other common soluble support material is PVA (Polyvinyl Alcohol), which dissolves in water. Here is an honest comparison.

Property	HIPS	PVA
Compatible model material	ABS	PLA, PETG (some grades)
Solvent	d-Limonene	Water
Dissolution time	2–16 hours	1–8 hours (warm water faster)
Solvent availability	Specialty supplier, online	Tap water
Solvent cost	$15–25 per 500 ml	Free
Solvent safety	Low-toxicity, flammable	Non-toxic, safe to drain
Moisture sensitivity	Moderate	Extreme — PVA degrades in days
Price per kg	$25–35	$50–80
Print difficulty	Similar to ABS	High — clogs easily if wet
Storage requirement	Airtight bag	Vacuum sealed, use immediately

When to choose HIPS over PVA:

• You are printing ABS (PVA is not compatible with ABS temperatures)
• You want lower cost per kilogram
• You cannot reliably keep filament bone-dry between prints
• Your print jobs run long and you cannot babysit the printer for PVA clog issues

When to choose PVA over HIPS:

• You are printing PLA and do not need an enclosure
• You want the simplest possible dissolution workflow (plain water)
• You have a reliable dry storage solution and can keep PVA sealed at all times

The short answer: if you print ABS, HIPS is the correct support material. If you print PLA, PVA is more practical.

Workspace Considerations

HIPS produces styrene fumes when melted, similar to ABS. The health risks from occasional hobby printing are considered low, but responsible practice means:

• Enclosure with carbon filtration: An enclosure that traps heat also traps fumes. Add a small carbon filter (activated carbon, not just a HEPA) to the exhaust port. Several commercial enclosures include these; DIY options work equally well.
• Room ventilation: Print in a ventilated space. Open a window or run a fan exhausting air outside when possible.
• Avoid small enclosed rooms without ventilation: A bedroom or small office with no airflow is not an appropriate space for extended HIPS or ABS printing.
• d-Limonene storage: Keep the dissolution container sealed when not in use. The smell is not hazardous but persistent exposure in a small workspace is unpleasant.

In practice, HIPS and ABS have comparable fume profiles. If you already print ABS comfortably with your current workspace setup, HIPS requires no additional precautions beyond what you already do.

Who Should Use HIPS — And Who Shouldn't

HIPS is the right choice if:

• You have a dual-extruder or IDEX printer and print ABS regularly — HIPS as soluble support is genuinely transformative for complex geometry
• You want a lightweight material for large display models, props, or RC components
• You need a material that machines and sands cleanly
• You want the benefits of an ABS-like material with slightly lower warping sensitivity

HIPS is not the right choice if:

• You have a single-extruder printer and want soluble supports — there is no practical way to use HIPS for this without a second toolhead
• You want acetone vapor smoothing — HIPS does not respond to acetone the way ABS does
• You are looking for a general-purpose material that is easy to start with — PLA or PETG are better defaults for beginners
• You print primarily PLA — PVA supports on a PLA print are simpler and do not require d-Limonene
• Your printer cannot reliably hit 95–100°C on the bed — HIPS will warp without adequate bed heat

Final Verdict

HIPS is a specialized material with a specific, excellent use case: soluble supports for ABS on dual-extruder printers. In that role, it performs better than PVA (which requires extreme dryness), costs significantly less, and is easier to tune. For ABS users with multi-material setups, it is close to a mandatory addition to the filament collection.

As a standalone material, HIPS is competent — lighter than ABS, easier to print, and easier to machine — but it occupies a narrow niche. Unless you specifically need those properties, PETG or ABS will serve most functional printing needs better.

The d-Limonene workflow sounds intimidating but takes an hour to set up and runs itself. Once you have printed a complex ABS part with zero support scarring, it is hard to go back to manual support removal.

If you have the hardware for it, HIPS earns its place.
