When 3D printed on a usual desktop 3D printer, there is no visible difference. When we reduced the triangle count x4 fold, the object’s features didn’t change much. In the image above, there is a 3D scan of a monkey puzzle tree trunk. A more accurate scan means more points and a heavier mesh. 3D scanning software calculates the distance between points of the scanned surface and creates the mesh. However, when it comes to uploading or sharing, this could cause a problem.
Such files are heavy in data and require powerful PCs to process. This helps designers to create the finest details. Usually, sculpting produces a lot of polygons and triangles.
What Objects May Need a File Size Reduction In this case, heavier files may crash the application and it won’t operate properly. Tinkercad, for example, allows importing files not bigger than 25MB. This had to be done to keep the website hosting expenses down. In the early days, some STL file repositories had an upload limit of 30MB, therefore files had to be reduced. One of the main reasons is to increase the sharing ability of an object. Instead of trying all the converters on the market, we will present to you 2 of the best pick we will add in the next part.– To share. Though converting is easy, choosing a suitable converter is troublesome for many because not all are reliable and secure to use. So, if your goal is to use your 3D printer and make a 3D prototype, you will need to convert PNG to STL. For publishing the 3D design in STL, you can’t add metadata to it even if you manually add it. Though the STL is used for 3D printing, the prototype you create isn’t perfect as it seems because it doesn't contain color and texture. Also, you cannot print a 3D model using a PNG format using a 3D printer. Lossless data compression and lossy data compressionĮven though it is a GIF alternative, you cannot make an image move in this format unless you use APNG. Standard Triangle Language or Standard Tesselation Language So, if you want to create a 3D model or object, this format is universally known, like how PNG is universally used and known on the web. This format has no color, texture, or CAD model attributes which isn’t ideal for being used in producing a final product. It perfectly works for prototyping, creating 3D designs, and computer-aided manufacturing, known as CAM. STL was introduced as part of the stereolithography printing technology for 3D printers. With the less color palette supported and patent-licensing of the GIF, PING, known as PNG today, fills the gap that the GIF can’t do, such as millions of color palettes supported and patent-free yet they are still images. PNG was introduced as a GIF alternative in late 1995.
