If you discover unselected surfaces, simply click on those surfaces until all is completed. This should turn the entire interior red. If you can be assured of all one surface, use Select, then double click on the interior. This will cause the surfaces to change color. When you load your STL file into MM, use Edit, Generate Face Groups. This image is of the model prior to modification: As your question does not include that program, I'll toss the Meshmixer method.

The tool also has an option to save the file to one of the non-standard formats that support colored faces such as VisCAM and SolidView which is perfect if you want to further process the STL in software which supports these formats.Only today, I learned of a solution for this sort of objective, but it uses Fusion 360 rather than Meshmixer or Meshlab. The STL file generated by the tool will contain only raw mesh/triangle data by default which is perfect for 3D printing. The standard STL file format does not support colored faces or vertices or texture information. The STL format can be either Text or Binary, our tools will support both formats. There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files. The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. We also have another version of this tool aimed at extruding images to color 3D models, this is only available to 3D file formats that support color such as 3MF.īlender, MeshLab, CAD Assistant, DAZ Studio This mode is ideal for simple images such as logos and other simple shapes such as coins (see our Coin examples in the library tab). The height of the extruded shape is again based on the pixel luminosity.
In Extrude mode our PNG tool behaves in a similar way to Standard mode except the tool attempts to find simple shapes in your image and it performs an Extrude operation on any shape found. This mode is ideal for the conversion of detailed heightmap images into 3D models. When this option is selected a white pixel will have a height of 0mm and a black pixel will have the height you have specified. The tool has a Invert Output option if you wish to reverse the model height calculations. A black pixel in your PNG will have a height of 0mm and not be included in the final 3D generated model, however a white pixel will have a height that you specify once your image is uploaded. In Standard mode our tool examines your 2D PNG image and based on the luminosity of each pixel, will create a corresponding "3D" pixel where the height of the pixel is determined by the pixel luminosity. PNG 2D to 3D STL, How Does It Work? Standard Mode (Heightmap) When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer. Although you can use an Ad Blocker, if you like our PNG conversion tool please consider white-listing our site. What if I am using an Ad Blocker, will that affect things? No specialist software is needed to run any of our conversion tools. Yes! Our PNG to STL tool will run on any system with a modern web browser.

Can I convert PNG to STL on Windows, Linux, Android, iOS or Mac OS?

The resulting STL file, once created is deleted 1 hour after upload and the download link will expire after this time. Yes, of course! We do not store the PNG file you submit to us. Our tools are under constant development with new features and improvements being added every week. We aim to create the most accurate conversions with our tools. How accurate is the PNG to STL conversion? We aim to process all PNG to STL conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient. How long does it take to convert my PNG to STL? When the PNG to STL conversion has completed, you can download your STL file straight away. How can I convert my PNG file to STL?įirst click the "Upload." button, select your PNG file to upload. Optionally, our tool will allow you to save to the non-standard color STL format. Our tool will save all STL files in binary format. The PNG image you upload can be any size, however our tool will resize it to a maximum of 600圆00 pixels for normal users and for those who have paid for a premium subscription this is increased to a maximum of 1000x1000 pixels. What is the maximum PNG image resolution I can upload?
