- Auto-Shutoff: Many portable guns have a safety feature that turns off the device if it overheats or tips over.
Cost-Effectiveness:
Portable heat guns can be more expensive than their corded counterparts, with prices ranging from $50 to $200. However, the convenience they offer often justifies the higher cost.
3. Industrial Heat Guns
Industrial heat guns are built for heavy-duty use and are designed to handle large-scale projects. They are powerful, with high-temperature outputs and robust construction, making them suitable for industrial settings.
Performance:
- High-Temperature Output: Industrial heat guns can reach temperatures up to 1,200°F (650°C), making them ideal for melting and smoothing thick layers of plastic.
- Heavy-Duty Construction: Built with durable materials, these guns can withstand prolonged use and harsh working conditions.
Ease of Use:
- Adjustable Settings: Most industrial models have precise temperature controls, allowing you to fine-tune the heat output.
- Ergonomic Design: Despite their size, many industrial heat guns are designed with comfort in mind, featuring padded grips and balanced weight distribution.
Safety Features:
- Thermal Overload Protection: Advanced safety features prevent the gun from overheating, reducing the risk of accidents.
- Cooling Jets: Some models have cooling jets to quickly cool the surface after heating, preventing warping or discoloration.
Cost-Effectiveness:
Industrial heat guns are the most expensive option, with prices ranging from $200 to $500. However, their durability and performance make them a worthwhile investment for professional use.

Step-by-Step Guide to Using a Heat Gun for Deburring
Deburring 3D printed models with a heat gun requires precision and care to avoid damaging the model. Follow these steps to achieve smooth, professional results:
1. Prepare Your Workspace
- Safety First: Ensure your workspace is well-ventilated to avoid inhaling harmful fumes. Wear protective gear, including safety goggles and gloves.
- Secure the Model: Place your 3D printed model on a stable surface to prevent it from moving during the deburring process.
2. Adjust the Heat Gun Settings
- Temperature: Start with a lower temperature setting and gradually increase it as needed. For most plastics like PLA and ABS, a temperature between 300°F (150°C) and 500°F (260°C) should suffice.
- Airflow: Adjust the airflow to a medium setting. Too much airflow can cause the material to warp, while too little airflow may not be effective in melting the burrs.
3. Begin Deburring
- Target the Burrs: Hold the heat gun at a 45-degree angle and start from a distance of about 2-3 inches (5-7.5 cm) from the model. Move the gun in a slow, steady motion over the rough edges and burrs.
- Melting the Burrs: As the heat melts the plastic, use the airflow to gently blow away the molten material. Avoid holding the gun in one place for too long, as this can cause the material to warp or burn.
4. Smooth the Surface
- Pass Over the Area: Once the burrs are removed, pass the heat gun over the area again to smooth out any unevenness. Keep the gun moving to prevent overheating and warping.
- Cooling: If your heat gun has a cooling jet, use it to quickly cool the surface after heating. This helps to set the plastic and prevent further warping.
5. Inspect and Repeat
- Check for Imperfections: Examine the model under bright lighting to spot any remaining burrs or imperfections. Repeat the deburring process on these areas as needed.
- Final Touches: For a polished finish, consider using fine-grit sandpaper or a polishing tool to smooth out any remaining rough spots.
6. Clean Up
- Dispose of Waste: Collect any molten plastic or debris and dispose of them properly.
- Clean the Heat Gun: Wipe down the heat gun and nozzle with a soft cloth to remove any residue or dust.
Conclusion
A heat gun is an invaluable tool for deburring 3D printed models, offering a precise and efficient way to smooth out rough edges and remove excess material. When choosing a heat gun, consider factors such as performance, ease of use, safety, and cost-effectiveness to find the best option for your needs. Whether you're a hobbyist working on small projects or a professional handling large-scale models, there's a heat gun out there that can meet your requirements.
By following the step-by-step guide provided, you can achieve professional-grade results in deburring your 3D printed models. With the right tool and technique, your models will look polished and ready for display or use.
