3D print: Tips to succeed in your 3D printing projects

It's time to take your projects to the next level! Some tips and techniques can help you improve the quality of your 3D prints, whether you're a hobbyist or a professional. This article will explore three valuable tips to help you succeed in your 3D printing endeavors.

1. Select the Best Software

With the plethora of options available in the market, choosing the right software can be a daunting task. However, selecting user-friendly software that supports common file formats and has built-in tools for creating optimized low poly models can make the process easier. Here are some recommendations when choosing the software that suits you best.

• ​​Look for software with a user-friendly interface

One of the key features of good software is its user interface. Look for software that is easy to navigate, has clear icons and labels, and is intuitive. A User-friendly interface will help you get started with 3D printing quickly and easily, even if you are a beginner.

• Check the file formats the software can export to

The most common file format for 3D printing is STL, but other formats may suit your needs better. Check the software’s list of supported file formats and see if they align with your project’s requirements. This will ensure that you can import and export files seamlessly between the software and your 3D printer.

• Ensure the software can create custom print settings

Custom print settings can be beneficial if you want to change the infill density, 3D print speed, or other parameters. Check if the software supports this feature and how easy it is to change these settings. Having this feature can help you optimize your model for 3D printing and improve its quality.

• Look for software that can slice your model into G-code

Cutting a 3D model into layers for printing is known as slicing. Some software can slice your model into G-code, a programming language that controls 3D printers. This feature can save time and effort and make printing more efficient. Look for software that has this feature built-in or that can integrate with an external slicer.

• Check if the software has a built-in simulator

A built-in simulator is a feature that allows you to preview your model and check how it will look before you print it. This feature can save you time and money by allowing you to make any necessary adjustments before printing. Look for software with this feature and see how accurate and useful it is.

• Make sure the software is regularly updated

As new technologies and features are developed, it’s important to have software that can take advantage of them. Regular updates ensure that the software stays current and functional and that any bugs or issues are addressed promptly. Check the software’s update history and see how frequently updates are released.

• Check the price of the software

Price is an important consideration when selecting software. Some software can be quite expensive, while others may have limited features or require additional purchases. Determine your budget beforehand and look for software that fits within it. Keep in mind that some free or open-source software can be just as effective as paid options.

2. Design parameters

When designing a 3D model for printing, there are many parameters to keep in mind to ensure a successful print. These design parameters are critical to avoid printing errors, such as warped or detached parts, and to ensure a structurally sound and visually appealing model. Below we will highlight some key design parameters to consider when designing for 3D printing.

• Watertight Design: Aim to make your design watertight by eliminating discontinuities on the surfaces of your 3D model. When designing a model, ensure that there are no holes or gaps in the surface that could cause printing issues. A watertight design is critical to avoid errors that may cause your print to fail.
  
  
• Manifold Geometries: Using manifold geometry makes for a successful print. Non-manifold geometries occur when the 3D shape is unfolded, and the normals of the 2D shape do not all point in the same direction due to a shared edge or two faces connected at a single point. Ensure your model is printable by checking for any T-type or bow-type non-manifold geometries and adjusting them to create a manifold shape.
  
  
• Wall Thickness: Assess your printing material and the height to determine whether your wall needs additional support. A wall that is already bolstered by ribs or webs can be thinner than a freestanding wall. Ensure that your walls are thick enough to prevent breaking or being too fragile. Wall thickness should be two or three times the nozzle's width.
  
  
• Strong Base: Adhesion is a huge difficulty with 3D printing. If your model or even a part of it doesn't stick directly to the 3D print bed when the first layer is printed, it could detach and warp your print resulting in much plastic, time, and effort down the drain. Avoid this by starting with a strong base. Avoid large flat surfaces, and round the corners of your 3D models to enhance the success of a clean print.
  
  
• Raft, Brim, or Skirt: You can use a raft, brim, or skirt to prevent your model from tipping over or experiencing a "bulge." A raft is a flat surface area made up of horizontal latticework, added beneath your part, and helps eliminate the elephant's foot and improves adhesion to the printer bed. A brim is a skirt attached to the edges of the model printed with an increasing number of outlines to create a large ring. Skirts surround the part but don't touch it, and they help warm up the extruder by establishing a smooth filament flow. These design parameters can help prevent common printing errors and ensure a successful print.

3. Consider the Material

Choosing the right material is crucial for achieving your final product’s desired mechanical properties, functional characteristics, or aesthetics. Here are some considerations and advice to keep in mind when selecting materials for 3D printing:

• Define your performance requirements: Before looking at specific materials, you should define your performance requirements based on factors like strength, flexibility, heat resistance, and chemical resistance. This will help you narrow your options and choose a material that meets your needs.
  
  
• Consider the properties of different materials: There are many different materials available for 3D printing, each with its unique properties and characteristics. For example, ABS is a popular plastic material that is strong and durable but can be difficult to print with, while PLA is easier to print with but is less strong. Nylon is another popular material that is strong and flexible but can be more challenging to print with than other plastics.
  
  
• Think about the intended use of your product: The intended use of your product will also play a role in determining which material to choose. For example, if you're printing a part that will be exposed to high temperatures or chemicals, you'll need a material that can withstand those conditions.
  
  
• Consider the cost: The cost of materials can vary widely depending on the type of material and the supplier. While it's important to choose a material that meets your performance requirements, you should also consider the cost of the material and whether it fits within your budget.
  
  
• Test different materials: Once you've narrowed down your options based on performance requirements and other factors, testing different materials before committing to one for your final product is a good idea. This testing will help determine which material works best for your application.
