STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
SGI (Silicon Graphics Image) is a raster image format associated with Silicon Graphics workstations. It is a bitmap file that can store black-and-white, gray-scale and color images, and may also contain color maps and alpha channels. SGI files are sometimes referred to as RGBs and can either use no image compression or RLE compression. Alternative extensions for the SGI format are BW, RGB and RGBA.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. Although it is fast, this software is extremely efficient in managing a wide range of conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert STLs. But at the same time, it will allow you to apply a wide range of editing options.
Start reaConverter and load all the .stl files you intend to convert into .sgi because, as opposed to most free online converters, reaConverter supports batch conversion. So you can save the time and energy you would lose with doing repetitive operations.
Select STLs from a folder or by drag-and-dropping them directly into the reaConverter window.
Go to the Saving options tab and decide where you want to save new .sgi files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Then pick the SGI as output format. To help you do this, a series of buttons is conveniently placed at the bottom of the reaConverter window, so you can simply press on the one you need or click Plus button to add new options.
Then simply press the Start button and your conversion will begin in no time!Try Free Trial Version
