You’ll achieve better HIPS support compatibility by focusing on three key areas: thermal alignment, environmental control, and proper solvent selection. First, match your bed temperatures between 90-110°C and align extrusion temperatures around 230°C for both HIPS and your primary material like ABS. Second, use an enclosed build chamber with controlled humidity and turn off cooling fans during initial layers. Third, choose limonene as your primary solvent for safe removal, though you should test compatibility first. Master these fundamentals to access advanced techniques.
Match Thermal Properties Between HIPS Support and Primary Filament Materials
When you’re setting up dual extrusion printing with HIPS support material, matching thermal properties between your support and primary filaments becomes critical for successful prints.
You’ll need to verify both materials share similar bed temperatures—HIPS requires 90-110°C, making ABS an ideal pairing since it uses the same range.
Your extrusion temperatures should align closely too; HIPS prints around 230°C while ABS works at 230-250°C.
Pay attention to thermal expansion coefficients, as mismatched materials create stress and layer delamination during cooling.
You’ll also want similar thermal conductivity—HIPS’s 0.22 W/m-K rating—to promote uniform cooling rates.
Synchronize your cooling fans and use gradual temperature changes to minimize warping and interface failures between materials. Since HIPS is soluble in d-limonene, you can easily remove support structures after printing without damaging your primary part.
Optimize Printing Environment for Consistent HIPS Support Performance
Creating the ideal printing environment for HIPS support material requires precise control over temperature, humidity, and adhesion factors that directly impact your print quality.
You’ll need an enclosed build chamber to maintain consistent temperature throughout the printing process, preventing warping and layer separation. Set your heated bed between 90-110°C for peak adhesion, and control humidity levels to prevent moisture absorption that degrades print quality.
Turn off cooling fans during initial layers to improve bed adhesion, then activate them as needed for later layers. Use adhesive solutions like Kapton tape, PET sheets, or ABS slurry on your build surface.
Reduce printing speeds during first layers and consider using rafts for enhanced adhesion. Monitor your filament’s condition, ensuring it’s dry and contaminant-free. HIPS dissolves cleanly in d-Limonene solvent, making it an excellent choice for complex geometries requiring complete support removal.
Select Appropriate Solvent Removal Method for Your Material Combination
Proper environmental conditions set the foundation for successful HIPS printing, but removing the support material requires careful solvent selection based on your primary filament type. Limonene stands as the primary recommended choice for dissolving HIPS supports without excessive damage to your print. However, you’ll need to evaluate your model’s base material compatibility carefully.
| Model Material | Recommended Solvent |
|---|---|
| ABS | Limonene (limited exposure) |
| ASA | Limonene (limited exposure) |
| PLA | Limonene (rarely used combo) |
| PETG | Limonene |
| PC | Acetone (with caution) |
While acetone dissolves HIPS almost instantly, it risks damaging ABS surfaces. You should test solvent effects on small print sections before full immersion to prevent irreversible damage. Ultrasonic cleaners can significantly accelerate the dissolving process while providing more controlled and consistent results than manual agitation methods.
Frequently Asked Questions
Can HIPS Supports Be Reused After Dissolving Them in D-Limonene Solvent?
You can’t reuse dissolved HIPS supports after they’ve been dissolved in d-limonene. However, you can reuse the limonene solvent itself several times, though its effectiveness decreases with each use.
How Long Does HIPS Filament Last in Storage Compared to PVA?
HIPS filament lasts considerably longer in storage than PVA because it’s less moisture-sensitive. You’ll find HIPS maintains stability for extended periods while PVA absorbs moisture quickly, shortening its shelf life considerably.
Is HIPS Support Material Safe for Food-Contact Printed Objects?
You shouldn’t use objects printed with HIPS support material for food contact unless the HIPS meets FDA regulations and you’ve removed all support material completely through proper post-processing.
What Bed Adhesion Methods Work Best Specifically for HIPS Support Structures?
You’ll get best results using ABS slurry on your heated bed at 110°C, combined with brims around support areas. Apply glue stick lightly and reduce cooling fans during first layers.
Can You Print HIPS Supports Without an Enclosed or Heated Chamber?
You can print HIPS supports without an enclosed chamber, but you’ll face increased warping, poor adhesion, and print defects. You’ll need slower speeds and extra bed adhesion measures.
In Summary
You’ll achieve better HIPS water-soluble support compatibility by matching thermal properties between your support and primary materials. Don’t forget to optimize your printing environment for consistent performance throughout the process. When you’re ready for post-processing, select the solvent removal method that works best with your specific material combination. These three strategies will help you overcome common compatibility issues and produce cleaner, more reliable prints with minimal support removal challenges.
