In this article, we will discuss the STL format, which is used for all the files in our catalog of models for CNC machines. You can purchase ready-made files or order custom 3D models in STL format on our website.
What is STL?
STL is a format that allows a three-dimensional object to be converted from a 3D model into a control program for CNC machines or 3D printers. STL contains information about 3D objects and is designed on a computer by a 3D modeler.
These files contain a layer-by-layer representation, taking into account the order of creating the product.
Subsequently, the control program will specify the cutting tool's path and the depth of its penetration.
A Few Historical Facts:
The STL format emerged in 1987, coinciding with the development of 3D printing technology (stereolithography). The name STL is an abbreviation of "StereoLithography," which translates to "volumetric lithography."
The company 3D Systems, with the help of the consulting group ACG, developed the first algorithm for creating 3D models.
Thus, the STL format was born. The code was made open-source, with the goal of making the format widely accessible and easy to use.
As a result, the innovation gained popularity and became widely adopted. Since its creation, the format has remained largely unchanged, with only a minor update introduced in 2009.
What Does the STL Format Represent?
An STL file consists of numerous tiny triangles connected by vertices, forming a three-dimensional shape. The more triangles there are, the more realistic the image.
What to Do After Receiving the File?
After purchasing a 3D STL file from our catalog or ordering a custom 3D model, you need to translate it into a language understandable by your 3D printer or CNC machine.
This format is opened using specialized software. There are many programs available, but for CNC machines, 3D Max and ArtCam are most commonly used.
About Quality:
A high-quality model should not have holes.
The main criterion for the quality of an STL file, which stores information about a 3D model, is its high precision, necessary for exporting triangles. The more complex the structure, the more triangles will be used.
The higher the quality, the more accurate the final part will be.
It is impossible to achieve excellent detail in a product if errors or defects were introduced during the 3D model development stage.
Therefore, it is advisable to order or purchase 3D models from experienced specialists, such as those available on our website. This ensures excellent results and a high-quality finished product.
Advantages and Disadvantages of STL Files:
Advantages of STL files include:
-
Wide availability and accessibility.
-
Compatibility with various programs.
-
Ability to transfer, publish, or share files.
-
Small file size.
Disadvantages of STL files include:
-
Lack of information about texture, color, or material (meaning STL is unsuitable for creating multicolored products, such as on a 3D printer).
-
Inability to embed metadata, such as copyright information.
-
Difficulty in modifying files (except for proportional scaling). For those who want to reuse, modify, or adapt models for different situations, we offer files in 3D Max format.
-
STL files are not suitable for modern high-resolution printers. In such cases, the OBJ format is preferable.
Where to Buy Models?
As mentioned earlier, you can purchase 3D models on our website.
We offer a wide range of STL files for any taste, suitable for any interior style and for creating various products. These include furniture, decor, toys, gifts, souvenirs, carved panels, bas-reliefs, figurines, busts, and much more.
