Do you have a pencil drawing that you'd like to see in 3D? Thanks to advances in 3D modelling and design, it's now easier than ever to transform your sketches into 3D models ready for printing. In this article, we explain how you can do it easily, and how to Additium 3D accompanies you through the process with its professional service of 3D Design and Scanning.
What do you need to convert a drawing into 3D?
To start with, it is essential that you have a digitalised version of your pencil drawing. The best way to do this is to scan the drawing at a high resolution, which will ensure that all details are captured, especially in images with fine lines. It is also advisable to clean up the image with a graphics editor, removing unwanted backgrounds or shadows and making sure that any colour or shadow transitions are clear. In this way, you will have an image ready to be converted into a 3D model.
Select the right software
There are several tools that allow you to transform a 2D image into a three-dimensional model. Here are some options depending on your needs and level of experience:
- TinkercadIt is a free and very intuitive online platform, ideal for those who are just starting out in the world of 3D modelling. It allows you to upload 2D images and quickly convert them into three-dimensional models with just a few clicks. It is perfect for simple and educational projects.
- 3D jungleThis tool allows you to upload an image and adjust its volume in 3D using two simple sliders. While the free version is sufficient for basic models, the paid version offers higher resolution and is useful for images with fine details.
- SolidWorksSolidWorks is widely used in professional environments and is ideal for both 2D and 3D design. Its precision and versatility make it an excellent tool for projects requiring technical detail and engineering accuracy.
- RhinocerosThe software is very versatile and stands out for its ease of use and powerful tools for the creation of complex models. It allows working with different formats and offers advanced rendering options, making it ideal for designers looking for flexibility and precise results.
- BlenderIf you are looking for a powerful and free tool, Blender is an excellent choice. It is open source and offers multiple functions both for the creation of static 3D models and for animation. At Additium 3D we use it mainly for editing figures and Maya.
- AutoCADCAD design software is an industry benchmark, known for its ability to generate accurate 2D drawings and 3D models. It is widely used in architecture and engineering, and its parametric design facilitates project modifications.
- 3DSlicerAdditium 3D uses this tool for projects in the medical sector. It is open source and designed specifically for 3D medical image visualisation and processing, making it a robust option for scientific and clinical applications.
- MeshmixerMeshmixer: Meshmixer is ideal for quick editing of .STL files, commonly used in 3D printing. It is a free tool designed by Autodesk that makes it easy to manipulate meshes and prepare models for printing. It is very useful for adjusting details in existing models or combining shapes efficiently.
With this variety of options, you can find the software that best suits your needs, whether you're just starting out in 3D modelling or looking for more advanced tools for specific projects.
4 Steps to model a drawing to 3D step by step
If you decide to try it for yourself, here are the basic steps to transform your 3D drawing:
- Import your scanned imageUse the software that best suits your level and upload the file.
- Create the basic shapes3D modelling tools: Use 3D modelling tools to give volume to the important parts of the drawing.
- Adjust the detailsCustomise the model by adding textures, shadows and the finest details.
- Export the fileSave the model in a format suitable for printing, such as .stl, and prepare it for sending to a 3D printer.
Improve the quality of your 3D printing
The level of detail of your print depends largely on the quality of the image and the settings you make in the software. For example, for images with very fine lines, one recommendation is to use a smaller nozzle on the 3D printer (around 0.25 mm). This helps to maintain the accuracy and quality of the printed model.
In Additium 3D, for example, we adjust the technical parameters to ensure that the result is of high quality. We use tools such as Meshmixer to optimise the files before printing, eliminating errors and ensuring a clean and accurate model.
Some of your most common questions
Below, we answer some of the most frequently asked questions we receive about how to convert pencil drawings into 3D:
How to make a drawing look 3D?
To make a 2D drawing look 3D, you need to digitise it and run it through 3D modelling software such as Tinkercad or Blender. These programmes will allow you to add volume and depth to the drawing.
Where to design in 3D for free?
There are several free platforms where you can design in 3D. Tinkercad is one of the most recommended options for beginners. Blender, on the other hand, is ideal if you are looking for a more advanced but still free tool.
How to make an image look 3D?
To convert an image into a 3D model, you can use programs that transform flat shapes into volume. This is achieved by defining the main areas and adding depth in the modelling software.
Where can I make 3D drawings?
If you want to make your own 3D drawings, you can use programs such as Tinkercad, Blender, or even AutoCAD, depending on your level of experience. At Additium 3D, we can help you create these drawings if you prefer a more professional approach.
How to convert 2D image to 3D printing?
First you must transform the 2D image into a 3D model using a modelling program. Then export the file in a format suitable for printing, such as .stl, and send it to a 3D printer. If you don't want to worry about the technical details, at Additium 3D we offer a complete service including modelling and printing.
Do you want to 3D print but don't have a design to do so?
At Additium 3Dwe do not only convert 3D drawingsbut we help you with a integral service of 3D Design and Scanning.
