What are STL Files?
To explain the concept of STL files in 3D printing with the purpose of comparing it to OBJ files, we will discuss the definition of STL files, how STL files work in 3D printing, and the advantages of using STL files in 3D printing. These sub-sections will provide you with the necessary information to understand STL’s role in 3D printing compared to OBJ files.
Definition of STL Files
STL files are a type of file format used in 3D printing. They contain a 3D model’s design info, described with triangular facets. These facets form a mesh structure, accurately representing the object’s surface. STL files are widely used for additive manufacturing processes.
They can also be used in CAM software and finite element analysis sims. Modifications to the STL model may be needed for certain applications.
Fun Fact: Chuck Hull created 3D printing, which he presented on May 13th, 1985. Create your own army of tiny figurines with a 3D printer and STL files – no months of learning needed!
How STL Files Work in 3D Printing
STL stands for Standard Tessellation Language or STereoLithography. It’s a polygon-based format, devised by Chuck Hull in 1986. STL is used in Computer-Aided Design (CAD) software, commonly referred to as 3D modeling software.
The file type consists of a triangular mesh, and it only contains the surface geometry of an object. It can be edited with a CAD software, and it is used in many sectors like manufacturing, architecture, and medicine.
Different CAD software produces different triangulations and densities. Therefore, it is important to adjust the tolerance value, chord height, and angular deviation for curvature correctly. This will ensure you get quality prints.
If the STL file is not properly uploaded, you may get unexpected results in your prints. This can lead to extra expenses on filament and wasted time reprinting flawed designs. So, make sure to double-check everything before uploading or sharing an STL file.
Using STL files in 3D printing saves you from explaining to your boss why the prototype looks like a blob of melted crayons.
Advantages of Using STL Files in 3D Printing
STL Files are a must-have for 3D printing. They contain info about the object’s shape, texture, and color. Using STL Files brings many advantages:

What are OBJ Files?
To understand OBJ files for 3D printing, you need to know their definition, how they work in the process, and their advantages. OBJ files store 3D models as a set of geometry and texture files. They are compatible with multiple 3D modeling software and can contain complex textures. In this section, we’ll explore these details of OBJ files to help you optimize your 3D printing experience.
Definition of OBJ Files
OBJ files are a standard 3D model file format. They contain info about an object’s geometry, texture details, three-dimensional position coordinates, texture coordinate mappings and lighting details. Plus, OBJ files store material properties like color, opacity, reflectance and shine.
It’s important to keep all related OBJ files together when sharing or archiving models. This can help avoid compatibility issues. Autodesk Entertainment Creation Suite Ultimate 2015 Release Notes mention Maya®, 3dsMax®, MotionBuilder™ and Mudbox™ software packages can import/export OBJ files.
So, OBJ files are essential for 3D printing and dad jokes.
How OBJ Files Work in 3D Printing
OBJ Files – they’re essential for 3D printing! They store data in a digital format, saving all the geometry of an object including its faces, textures, and colors. So, let’s look at how OBJ Files work with 3D Printers:
| What are OBJ Files? | How do they work with 3D Printers? |
|---|---|
| A file format for 3D object data. | Contains info such as vertices, faces and polygonal lines. |
| The files save the geometry. | Loaded into slicing software, which calculates boundaries of layers. |
| OBJ files store texture maps, transparency and illumination. | Polygons have coordinates assigned to them, creating a 3D coordinate system. |
| Can be exported from most major design programs. | Printers translate info into slices known as layers that build up the object one layer at a time. |
You can also manipulate OBJ Files with CAD tools like Blender and AutoCAD. This way you can edit objects before printing, ensuring compatibility with different printers and software.
