Get Started: How to Make Supports for 3D Printing

Posted by

3D printing has revolutionized the world of manufacturing, allowing for the creation of complex and intricate designs that were once impossible to produce with traditional manufacturing methods. However, 3D printing also comes with its own set of challenges, such as the need for supports to keep the printed object stable during the printing process. Without proper supports, the object may warp or collapse, resulting in a failed print.

Fortunately, creating supports for 3D printing is a relatively simple process that can be done using specialized software. These supports are essentially temporary structures that are printed alongside the main object and are designed to hold it in place during printing. Once the printing is complete, the supports can be easily removed, leaving behind a clean and finished object. In this article, we will explore the different types of supports available and provide step-by-step instructions on how to create them using popular 3D printing software.

Materials

When it comes to 3D printing, choosing the right materials is essential for creating reliable and sturdy supports. In this section, we’ll take a look at two main materials that are commonly used for 3D printing supports: filament and support material.

Filament

Filament is the most common material used for 3D printing supports. It is a thermoplastic material that is melted and extruded through a nozzle to create the support structure. There are several types of filament available, including ABS, PLA, PETG, and nylon. Each type of filament has its own unique properties and is suitable for different applications.

ABS filament is a strong and durable material that is ideal for creating supports that need to withstand high temperatures. PLA filament, on the other hand, is a biodegradable material that is easy to print with and is perfect for creating supports that don’t require high strength.

Support Material

Support material is another type of material that is used for 3D printing supports. It is a water-soluble material that is used to create structures that support the main object during the printing process. Once the printing is complete, the support material can be dissolved in water, leaving behind the finished object.

One of the advantages of using support material is that it allows for the creation of more complex shapes and designs. It can also be used to create overhangs and bridges that would be impossible to print without support.

There are several types of support material available, including PVA, HIPS, and BVOH. Each type of support material has its own unique properties and is suitable for different applications. PVA is a popular choice for creating supports for PLA prints, while HIPS is commonly used for ABS prints.

In summary, choosing the right materials for 3D printing supports is essential for creating reliable and sturdy structures. Filament and support material each have their own unique properties and are suitable for different applications. By selecting the right materials, you can ensure that your 3D prints are successful and meet your needs.

Design Considerations

When designing supports for 3D printing, there are several considerations to keep in mind to ensure a successful print. Some of the key factors to consider include overhangs, bridging, and support density.

Overhangs

Overhangs are areas of a design that extend out from the base of the print, creating an unsupported section that can cause the print to fail. To avoid this, it is important to design the object with a gradual slope, rather than a sharp angle. Additionally, adding support structures can help provide the necessary support to prevent the print from failing.

Bridging

Bridging refers to the ability of a 3D printer to create a bridge between two points without the need for support structures. To achieve successful bridging, it is important to ensure that the distance between the two points is not too great. Additionally, using a lower layer height can help improve the quality of the bridge.

Support Density

Support density refers to the amount of support material that is added to a print to ensure its success. It is important to find a balance between support density and the quality of the final print. Too little support can result in a failed print, while too much support can result in a print that is difficult to remove from the support structures.

To achieve the right balance, it is important to consider the orientation of the print and the type of material being used. Additionally, adjusting the support density in different areas of the print can help ensure a successful outcome.

Overall, by considering these design factors when creating supports for 3D printing, you can ensure a successful and high-quality print every time.

Types of Supports

When 3D printing, supports are often required to help stabilize the model during printing. There are several types of supports available, each with its own benefits and drawbacks.

Tree Supports

Tree supports are a popular choice due to their ability to provide support without taking up too much space. They are designed to branch out from the model and provide support at key points. This makes them ideal for complex models that require support in multiple areas. Tree supports are also easy to remove, as they can be snapped off at the base.

Block Supports

Block supports are a more traditional type of support that is used to provide stability to the model. They are typically placed at the base of the model and are designed to prevent it from tipping over during printing. Block supports are a good choice for models that have a large surface area and require a lot of support.

Pillar Supports

Pillar supports are similar to block supports, but they are designed to provide support at specific points throughout the model. They are typically used for models that have a lot of intricate details that require support. Pillar supports can be difficult to remove, as they are often tightly integrated into the model.

When choosing a type of support, it is important to consider the specific needs of the model. Tree supports are ideal for complex models, while block supports are better suited for models with a large surface area. Pillar supports are a good choice for models with intricate details that require support at specific points.

Printing Supports

When it comes to 3D printing, supports are an essential component that helps to stabilize the print and prevent it from collapsing. In this section, we will discuss two critical aspects of printing supports: support interface and support placement.

Support Interface

The support interface is the part of the support structure that touches the print bed. It is crucial to have a good support interface to ensure that the support structure adheres well to the bed and doesn’t move during printing. Here are some tips for creating a good support interface:

  • Increase the thickness of the first layer of the support structure to ensure better adhesion to the bed.
  • Ensure that the support interface is in contact with the bed and not hovering above it.
  • Use a raft to improve the support interface’s adhesion to the bed.

Support Placement

Support placement is the process of deciding where to place the supports on the print. It is essential to place the supports in the right areas to ensure that the print doesn’t collapse during printing. Here are some tips for placing supports:

  • Place supports in areas that have overhangs or bridges.
  • Avoid placing supports in areas that will be visible in the final print.
  • Use support blockers to prevent supports from being placed in specific areas.

In conclusion, supports are a crucial component of 3D printing, and it is essential to understand how to create a good support structure. By following the tips outlined in this section, you can ensure that your prints come out stable and free from defects.

Post-Processing

Removing Supports

After your 3D print has finished, the first step in post-processing is to remove the supports. This can be done using a variety of tools such as pliers, flush cutters, or even a knife. It’s important to be careful when removing supports, as you don’t want to damage the print itself.

One helpful tip is to use support structures that are easy to remove. This can be achieved by adjusting the support settings in your slicing software. Additionally, you can use support structures that are designed to break away cleanly, such as tree supports.

Finishing the Print

Once the supports have been removed, it’s time to finish the print. This involves removing any remaining imperfections and smoothing out the surface. Here are some methods you can use:

  • Sanding: Use sandpaper to smooth out the surface of the print. Start with a coarse grit and work your way up to a finer grit for a smoother finish.
  • Filing: A file can be used to remove any rough edges or imperfections.
  • Chemical smoothing: Certain materials, such as ABS, can be smoothed using acetone. This involves placing the print in a container with acetone vapors for a short period of time.

It’s important to note that not all prints require finishing. If you’re happy with the way your print looks straight off the printer, there’s no need to do any additional post-processing.

In conclusion, post-processing is an important step in the 3D printing process. By carefully removing supports and finishing the print, you can achieve a high-quality final product.
