File types for 3D modeling and 3D printing

Almost everyone knows what types of files are used to save images: PNG, JPG, BMP, TIFF and others. But what about volume models? It would seem that we are adding a third dimension, but the file size is often smaller than even the image of the same model. In this article, we will tell you everything you need to know about files for storing models and even more: conversion methods, features of each type of file, and the file format for 3D printing.

3D model storage features

Unlike images, the voxel (voxel - volumetric pixel) storage method has not taken root in the world of 3D models. Only a few craftsmen use it when creating games or in scientific research. This is due to the history of the emergence of three-dimensional graphics: unlike the appearance of photography, three-dimensional graphics were originally created on a computer, and were used for animation. Voxels are much more difficult to animate, so they began to use the polygon storage method instead: the entire model consists of many polygons - triangles that have three points. It's like creating sculptures out of paper - by putting together a lot of flat pieces, you can get something voluminous and even smooth.

Dolphin Polygon Model

Although this method of saving as polygons cannot be called raster, these methods have much in common: the impossibility of increasing the quality, the direct relationship between the quality and file weight, ease of editing. This is the most practical format for saving and using models in 3D printing, but not the only one. Next, we will look at the most popular formats for storing 3D models.

Universal 3D Model File Formats

In fact, there are as many different methods for storing 3D models as there are for storing photos and videos. But there are also universal formats that, although with some restrictions, can be opened in almost any program.

STL

Contrary to misconceptions, STL was not originally intended for artistic modeling. It was developed by the Albert Consulting Group and was intended for an early 3D printing method - stereolithography. Hence the name of the file - STereoLithography. After some time, the company openly published the format and since then it has gained immense popularity.

The STL format is widely used due to the simplicity of its structure: polygons (facets) and their normals. The former are needed to set the surface, and the latter to indicate where the outer side of the polygon is located. Therefore, this format can be considered the most universal.

Comparison of CAD model and STL model

Due to the fact that the model is defined using many triangles, it is impossible to accurately define curved surfaces, because this would require an infinite number of triangles, and therefore an infinite data store. But when used in 3D printing, this minus is not so important, since the accuracy specified using triangles is higher than the printing accuracy.

OBJ

This format is very similar to STL, but differs in the ability to apply textures, set the material and store other information. Therefore, OBJ can be called an extended version of STL and is mainly intended for artistic modeling programs such as Blender, Autodesk Maya, 3Ds Max, Meshlab and others.

Processing an OBJ model in Blender

STEP

Now we are moving on to the engineering side of 3D modeling, because STEP is the only format that can be opened in any engineering modeling program and freely edited with the tools built into the program. STEP was originally developed as a world standard format for storing products on a computer, and was intended for a complete development cycle of a part. That is why all serious engineering modeling and physical simulation programs can work with this format. A distinctive feature of STEP is its high accuracy: the model is created with tools that allow you to set curves using formulas. Therefore, the precision in this format is infinite: no matter how much you increase it, the curved line will remain a curve, and will not become a lot of straight lines.

Creating a model in CAD SolidWorks

To create models in STEP format, CAD (Computer-Aided Design) is used. Thanks to the ISO standard, all CAD programs can work in this format. But not all data is freely transferred from one program to another via STEP. For us, the most important thing is the transfer of model geometry, and simulations, material and other data that the STEP format does not store are of secondary importance.

Proprietary formats

This category includes file formats that can only be opened in one program - in which the files were created. They are intended only for storing projects, often they cannot be used in 3D printing. An exception is the Ultimaker Cura slicer, which has the ability to add plug-ins that allow you to open files of programs such as Inventor, Siemens NX, Solidworks and others directly from the slicer.

Engineering programs

As mentioned earlier, these programs are called CAD. Since this software is often intended for production, they also have a common file format (STEP). Some programs, often produced by one company, allow you to work in a common ecosystem. For example, in many of Autodesk's engineering software, format compatibility can be found: Fusion 360 can open a file created in Inventor. But with this method of opening, some information about the product will still be lost, for example, information about the physical simulations performed. Therefore, if the part is not developed to the end, you should not move it between different programs.

Art programs

This category includes programs created for visualization: animation, special effects, creation of figures and models for video games. Unlike the previous case, chaos reigns in artistic modeling programs. Each program has its own format, and the general STL format limits the functionality of each program to the simplest tools. But this is enough to create models that will later be printed on a 3D printer, since only the geometry of the model is important.

Gcode - format for 3D printing

Actually Gcode is more than just a file format. It is a separate programming language. But instead of executing commands by a computer, commands in this language are executed by a 3D printer. Initially, this language was developed for complex CNC machines, and a 3D printer is one of the simplest representatives of this type of device. Unlike previous formats, gcode can be easily edited manually, thereby giving commands to the printer directly, bypassing the computer. With this, you can create macros that make it easier to work with a 3D printer. You can read more about working with the gcode language and creating macros in an article on our website.

3D model file format conversion

If you have a need to move the model between programs for 3D modeling, then you should determine in which group the program is from where and where you want to move the model. If you are transferring it from one CAD program to another, then it is best to use the STEP format so as not to limit the number of tools for further modeling. In all other cases, the only option is the STL format, which some CAD systems can recognize and in which art programs can save the model. It should be taken into account that when transferring a model from an art program to CAD, each polygon is transferred as a separate surface, so working with STL files in engineering programs can cause difficulties both in processing and in simple viewing of the model. This is due to the principles of CAD: it performs the processing of each surface separately, and the more surfaces, the more calculations need to be performed for one operation.

Tip: if the quality of the model is not so important when transferring a model from an artistic modeling program to CAD, then it is better to reduce the number of polygons as much as possible. Thus, the load on the computer is reduced and the speed of processing the model in CAD is increased.
