3D printing technology is an invaluable tool for prototyping and manufacturing parts, but it is not without its limitations. One such limitation is related to overhangs. An overhang is any part that extends beyond a 45° angle from the horizontal plane; any angle greater than 45° will require support structures for a successful print. The need for support structures is due to the natural sagging and drooping of the material during the printing process as it is being laid down. The complexity of the overhang’s structure and the quality of the surface finish can be dependent on the resolution of the printer used and the material being printed. After the printing process is complete, the support structures must be carefully removed from the part to avoid damaging it.
To gain optimal results from 3D printing overhangs, the material used should be appropriate to the design, printer resolution should be considered, layers should be kept thin, and supports should be strategic and minimised as much as possible. With proper planning and design, 3D printing overhangs can be successful despite inherent limitations. Overall, 3D printing is an economical and efficient way to create small batches of parts quickly and cost-effectively.

What are the best materials to use for 3D printing overhangs
3D printing overhangs can be a tricky process, but luckily, there are materials that are both strong and rigid enough to support the weight of the overhang while also being relatively easy to print. PLA, PETG, and ABS are among the best materials to use for 3D printing overhangs due to their strong layer adhesion, support for heavier builds, and easier post-processing. PLA filaments provide good adhesion between layers and provide medium levels of rigidity and strength, making them ideal for several applications such as overhangs, bridge printing, and parts that require flexing. Similarly, PETG filament is known for its superior strength, layer adhesion, and chemical resistance and is great for complex prints that require bends and curves. Lastly, ABS filaments boast increased chemical and temperature resistance, making it particularly popular for shock-resistant 3D prints, as well as for prints that require heat to mold. Any of these materials can work for 3D printing overhangs, but when used together in conjunction with proper settings, they can create a strong and reliable print job.
When 3D printing overhangs, adding supports is essential. Without them, the part may collapse, compromising the overall quality and integrity of the print. Supports can be added manually with the aid of 3D printing software, or programmed into the software to be generated automatically. PVA (polyvinyl alcohol), HIPS (high impact polystyrene) and PLA (polylactide) are the most popular materials that can be used for supports.
In some cases, printing supports from a soluble material is recommended, as it can be removed from the print afterwards and offers a simpler post-processing experience. PVA is one of the most popular materials for 3D printing supports, but PLA and HIPS can be used as well. It’s important to determine the material beforehand, as some prints will require a different support material to be used.
For a comparison of the most common materials used to print supports, please refer to the table below.
Material | Strength | Ease of Removal |
---|---|---|
PVA | Medium | Easy |
HIPS | High | Difficult |
PLA | Low | Difficult |
No matter what material you choose for your supports, always use a brim or skirt on the build plate, to ensure that all of the supports are securely adhered, and can provide the necessary structural stability.
How does 3D printing handle overhangs and large angles?
3D printing is made even more impressive by its ability to handle large angles and overhangs through the use of “support structures”. This process involves printing additional pieces of material next to the main object that serve as a foundation or scaffold for hard-to-reach surfaces. The support structures can then be detached from the object effortlessly after the 3D printing is finished. Utilizing support structures for 3D printing helps reduce the potential for failed prints caused by overhangs and difficult angles since it ensures that regions are kept stable and held in place during the printer’s operation. Invoking support structures goes hand-in-hand with other clever 3D print techniques, such as increasing the layer height, decreasing the infill percentage, and deploying rafts for large model prints. This combination of countermeasures ensures the 3D printing process is smooth and successful.
By combining the benefits of 3D printing with the ability to quickly and precisely produce overhangs, manufacturers can achieve parts with intricate details at a much faster speed and lower cost than ever before. Additionally, manufacturers no longer need to expend additional time on designing support structures due to the capabilities of 3D printing. With a 3D printer, manufacturers can print layers of their design directly onto the print bed upon which the part will be printed, drastically reducing the need for support structures. This efficiency in production and design makes 3D printing the ideal choice for producing overhangs.
