3DPEA - PNG to STL Converter

What conversion methods does 3DPEA use to turn a PNG into an STL file?

3DPEA offers four conversion modes: Stander and Stander Color, which create models based on heightmaps, plus Extrude and Extrude Color, which add depth to the image as a uniform extrusion. You can customize the depth, resolution, and smoothing for each approach. The choice between modes depends on whether you want the image's brightness values to determine height variation or a flat extrusion of the original shape.

Can I batch convert multiple PNG files to STL at once, or does 3DPEA process files one at a time?

The free online version converts one file at a time. If you need to process multiple PNGs in a batch, 3DPEA offers ConvUtils, a desktop application that handles offline batch conversion, though pricing for that app is not specified on their website.

How does 3DPEA handle transparency in PNG files?

3DPEA converts transparent areas in your PNG to either pure black or pure white, depending on which setting you choose. This is a simplified approach; if your design relies on partial transparency or gradients in the alpha channel, you may need to flatten or adjust your PNG before conversion.

What output formats besides STL can 3DPEA generate for 3D printing?

3DPEA supports 50+ 3D model formats for output, though the tool does not list every format on its public page. Check the format dropdown during your conversion to see the full range available, or contact the maker directly if you need a specific format not listed online.
