How To Design Your Own 3D-Printed Blueprint

A 3D-printed green elephant and a pink lizard sit on a white table. Wooden toys lie directly behind them.

Additive manufacturing, or 3D printing, is an innovative hobby and business practice that can create many kinds of visually appealing, practical products. However, you can start creating without a blueprint for the machine to follow. Find out how to design your own 3D-printed blueprint with these steps.

Define Your Project Goals

There are a couple of questions to ask yourself when designing the product. First, what is the purpose of your 3D model? Whether it’s a prototype, a decorative item, or a functional part, think about its structure.

What material will you use for 3D printing? PLA, ABS, and resin have unique properties that will affect the blueprint.

For many manufacturers, the design process of printing 3D tools involves trial and error. Clarify your goals, plan out multiple designs, and prioritize both form and function for the 3D model.

Start With a 2D Sketch

Use computer-aided design (CAD) software to draw a simple 2D outline. With the foundational layer of your 3D-printed blueprint, pay close attention to the dimensions, proportions, and connections of the design. Whether it has multiple parts or is a singular piece, you can view the model from all angles before running the blueprint through the software.

Choose the Right CAD Software

To create your blueprint, you need CAD software. Beginner-friendly tools, such as Tinkercad, have an intuitive drag-and-drop interface. Advanced software, including Fusion 360 and Blender, offers more flexibility and precision for complex designs.

Choose a platform that matches your skill level and the complexity of your project. In some cases, it’s better to start with Tinkercad, and then move up to using advanced software.

Create and Refine the 3D Model

Add depth and height using the extrusion tools to bring your 2D sketch into the third dimension. To refine the model, round the edges, smooth the surfaces, or add details. Refining your 3D model will help you avoid defective parts and keep the shape structurally sound.

Test Your Blueprint With Simulations

Most CAD software includes simulation tools to check for errors. Use these features to identify weak points in the system, such as structural imbalances. By resolving potential problems during the design phase, you’ll save time, material, and frustration when printing.

Export the File in the Correct Format

Once the blueprint is ready, save it in a format your 3D printer can read. Stereolithography (STL) is the most common format; it simplifies designs into a series of triangles that the printer can interpret. Double-check your file for open edges or gaps, as they can cause printing issues.

By carefully planning and refining your 3D blueprint, you’ll be able to print out anything for your home or business. Start small, refine your skills, and don’t shy away from experimenting with designs!
