  • Start with a sketch: Before you start designing, it’s a good idea to sketch out your ideas on paper. This will help you visualize your design and make any necessary adjustments before you start working in the software.
  • Use reference images: If you’re designing something that already exists, like a car or a building, it’s a good idea to use reference images to help guide your design.
  • Keep it simple: When you’re first starting out, it’s important to keep your design simple. Don’t try to create anything too complex, as it can be overwhelming and difficult to print.

Once you’ve created your design, it’s important to test it before printing. Many software options offer a preview mode, which allows you to see what your model will look like once it’s printed. Make any necessary adjustments before sending your design to the printer.

In summary, choosing the right software and creating a simple, well-planned design are key to making a successful 3D print model.

Preparing the Model for 3D Printing

Before printing your 3D model, you need to prepare it properly. In this section, we will discuss the two most important steps in preparing your model for 3D printing: exporting your design and checking and fixing errors.

Exporting Your Design

To print your 3D model, you need to export it in a format that your 3D printer can understand. The most common file formats for 3D printing are STL and OBJ. Make sure to export your design in the correct file format.

When exporting your design, you should also consider the following:

  • Scale: Make sure your model is scaled correctly for printing.
  • Orientation: Position your model in the best orientation for printing.
  • Resolution: Choose the appropriate level of resolution for your model.

Checking and Fixing Errors

Before printing your 3D model, you should check it for errors. Common errors include non-manifold geometry, flipped normals, and intersecting faces. These errors can cause problems during printing and result in a failed print.

To check your model for errors, you can use a 3D printing software or an online tool. Some 3D printing software, such as Blender and Meshmixer, have built-in error-checking tools. You can also use online tools like Netfabb and MakePrintable.

If your model has errors, you need to fix them before printing. Some errors can be fixed automatically by the software, while others require manual fixing. Make sure to check your model thoroughly for errors before printing.

In summary, preparing your 3D model for printing involves exporting it in the correct file format and checking it for errors. By following these steps, you can ensure a successful 3D print.

Printing the Model

Once you have created or downloaded your 3D model, it’s time to print it out. Here’s how to do it:

Choosing the Right Printer

When it comes to 3D printing, there are many different types of printers available on the market. Some printers are more suited for beginners, while others are designed for more advanced users. Here are a few things to consider when choosing a 3D printer:

  • Build volume: This refers to the maximum size of the object that the printer can create. Make sure the printer you choose has a build volume that is large enough for your needs.
  • Filament compatibility: Different printers use different types of filament. Make sure the printer you choose is compatible with the type of filament you plan to use.
  • Price: 3D printers can range in price from a few hundred dollars to several thousand dollars. Consider your budget when choosing a printer.

Loading Filament

Before you can print your model, you need to load filament into your printer. Here’s how to do it:

  1. Turn on your printer and navigate to the filament loading menu.
  2. Cut a length of filament and insert it into the printer’s filament loading port.
  3. Wait for the printer to heat up and extrude a small amount of filament to ensure that it is flowing correctly.

Printing Your Model

Once your printer is loaded with filament, it’s time to print your model. Here’s how to do it:

  1. Use slicing software to prepare your model for printing. This software will convert your 3D model into a series of instructions that your printer can understand.
  2. Transfer the sliced model to your printer and start the print job.
  3. Monitor the print job to make sure everything is going smoothly. If you notice any issues, such as warping or layer separation, you may need to adjust your printer settings or try printing the model again.

That’s it! With these steps, you should be able to print your 3D model with ease.


Once your 3D print is complete, you’ll need to remove supports, finish, and clean the model. Here’s what you need to know.

Removing Supports

Most 3D prints require supports to hold up overhangs and other complex geometries. These supports are typically made of the same material as the model and must be removed after printing.

To remove supports, you’ll need a pair of pliers or wire cutters. Carefully clip the supports away from the model, being careful not to damage the model itself. If there are any remaining bits of support material, you can use a small file or sandpaper to smooth them out.


After removing the supports, you may need to finish the surface of your model. This can involve sanding, filing, or otherwise smoothing out any rough spots or imperfections.

If you’re working with an ABS or PLA model, you can use a solvent like acetone to smooth out the surface. Simply apply a small amount of acetone to the surface with a brush or cloth and let it evaporate. This will help to melt and smooth out the surface of the model.

Cleaning Your Model

Finally, you’ll need to clean your model to remove any debris or residue left over from the printing process. This can involve washing the model with soap and water or using a specialized cleaning solution.

If you’re working with a resin model, you’ll need to cure it under UV light before cleaning. This will help to harden the resin and make it more durable.

In conclusion, post-printing is an essential part of the 3D printing process. By removing supports, finishing the surface, and cleaning your model, you can ensure that your final product looks and functions as intended.


In conclusion, creating a 3D print model requires a combination of technical skills and creativity. It is not a simple process, but it is an incredibly rewarding one. Here are some key takeaways from this article:

  • Design software: You will need to use 3D design software to create your model. There are many options available, so choose one that suits your needs and budget.

  • Model preparation: Once you have designed your model, you will need to prepare it for printing. This involves checking for errors, scaling it to the correct size, and adding supports if necessary.

  • Printing: When you are ready to print, make sure you have the right materials and settings for your printer. Experiment with different settings to find the best combination for your model.

  • Post-processing: After printing, you may need to do some post-processing to clean up the model and remove any supports. Sanding, painting, and other finishing techniques can also enhance the final result.

Remember, creating a 3D print model is a process that takes time and patience. Don’t be afraid to experiment and try new things. With practice, you can create amazing models that showcase your creativity and technical skills.
