Smith3D ABS Pro Filament 1.75mm 1kg (ABS+) – Tough, Heat-Resistant Engineering 3D Printer Filament
Smith3D ABS Pro is our upgraded ABS+ engineering filament designed for functional 3D prints that need toughness, heat resistance, and post-processing options. Compared to standard ABS, ABS Pro is formulated for more consistent printing and strong layer bonding (results vary by printer, enclosure, and settings).
If you’re printing brackets, mounts, housings, tool parts, or prototypes that need to survive real-world use, ABS Pro is a great step up from PLA when heat and impact resistance matter.
Smith3D ABS Pro Key Features
- Tough & Impact Resistant – Built for functional parts
- Heat Resistant – Suitable for warm environments (often ~90–100°C, application dependent)
- Strong Layer Adhesion – Reliable interlayer strength for working prints
- Great Finish Options – Sand, drill, paint, and acetone vapor smooth
- Reliable Feeding – Consistent diameter for steady extrusion
- 1.75mm / 1kg Spool – Standard size for most FDM/FFF printers
Recommended ABS Pro Printing Settings
| Parameter | Recommended Value | Notes |
|---|---|---|
| Nozzle Temperature | 235–265°C | Start around 245°C and tune for layer bonding |
| Bed Temperature | 90-110°C | Higher temps help reduce warping |
| Enclosure | Recommended | Helps prevent warping and layer splitting |
| Print Speed | 40–80mm/s | Slower speeds can improve layer bonding |
| Cooling Fan | 0–20% | Minimal cooling for strength and warp control |
ABS Pro vs PLA vs PETG vs ASA (Quick Comparison)
| Material | Why Choose It | Tradeoffs |
|---|---|---|
| ABS Pro (ABS+) | Tough functional parts + better heat resistance than PLA | Benefits from an enclosure; can warp; ventilation recommended |
| PLA | Easiest printing + great surface finish for prototypes and models | Lower heat resistance; can soften in warm environments |
| PETG | Good durability + easier printing than ABS for many printers | Can string; heat resistance varies by brand and part design |
| ASA | Excellent outdoor UV resistance + strong functional performance | Typically needs enclosure and good bed adhesion, similar to ABS |
Best Uses for Smith3D ABS Pro
- Functional Parts – Gears, brackets, housings
- Automotive Components – Under-hood and interior parts
- Tool Handles – Heat-resistant grips
- Electronics Enclosures – Heat-resistant cases
- Prototypes – Engineering test parts
- Post-Processed Parts – Smooth finish via sanding or acetone vapor
ABS Pro Printing Tips (Checklist)
- Heated bed on – Commonly 90–110°C (at least ~80–100°C) to help reduce warping.
- Cooling low – Keep part cooling fan off or very low unless bridging needs it.
- Use an enclosure – Especially for bigger prints to prevent warping and layer splitting.
- Bed adhesion matters – Clean your surface and use a suitable adhesive if corners lift.
- Ventilation – Print in a well-ventilated area (ABS materials can produce odor).

Smith3D ABS Pro FAQ
Q: Can I print ABS without an enclosure?
A: Small parts may work, but an enclosure is strongly recommended for ABS Pro. Without one, larger prints are more likely to warp or split.
Q: Is ABS stronger than PLA?
A: ABS Pro typically offers better impact resistance and heat tolerance than PLA. PLA can be stiffer, but it softens at lower temperatures. Choose based on your part’s real-world conditions.
Q: Can I acetone smooth ABS Pro?
A: ABS Pro (ABS+) can often be acetone vapor smoothed. Use appropriate safety precautions (ventilation, fire safety) and test on a small print first to dial in exposure time.
Q: How do I reduce warping and corner lift?
A: Use an enclosure, increase bed adhesion (clean surface + suitable adhesive), add a brim, and keep cooling low to maintain stable part temperatures.
Q: Does ABS Pro smell when printing?
A: Many users notice odor with ABS materials. Print in a well-ventilated space and avoid breathing fumes.
