STL File Converters: 10 Best Options to Try
Originating in the late 1980s to accommodate early SLA 3D printers, the STL file format has now become an industry standard file format for both 3D printing and modeling. However, new file formats have emerged as CAD has developed, which could make compatibility more of a challenge. Simplifying connection with 3D editors and slicers is as easy as converting 3D models to the universal STL format, which eliminates compatibility problems. Below, you'll find a variety of choices for easy file conversion, both online and offline.
1. SelfCAD
SelfCAD is an easy to use STL file converter that comes in the first position in our list. You can use it to create 3D models from scratch using various 3D modeling tools like freehand drawing and sketching, image to 3D model, and other advanced modification and deformation tools that you can use to edit files created in other programs. For example, you can import an STL file and simplify it as shown in the video below.
SelfCAD also supports majority of the common 3D file formats. You can import them by going to File > Import. After importing,convert it to your preferred file format by going to File > Export then choose the file format.
In addition to 3D modeling tools, SelfCAD also comes with an in-built online slicer that you can use to slice your files and generate the G-code to send to your 3D printer. The video below shows how SelfCAD slicer works.
