File Size

Steve Trimmer Apr 19, 2017 06:59AM PDT

I am designing parts in FreeCadd 16 I can save export in *.obj and *.stl. The file sizes are significantly different, Is 1 type better to use for precision or finish on the part?
Is the a maximum file size limit on the printer or the interface at New Matter? Some prints seem to stop prior to completion.

Hello Steve,

Thank you for your question. The MOD-t was designed to print .STL and .OBJ files through the New Matter website. To answer your question about the file size difference between .OBJ and .STL files. OBJ files are considered to be more complex than .STL files because they are able to represent texture and color. However, depending on what you are designing and attempting to print it is likely that you may want to go with an .STL file and also ensure that you are designing in “mm” as your unit of measurement.

Also, when designing your items it is important to keep in mind that the New Matter site has a 100MB file size limit. Lastly, when you have send a file to print it is important that you wait for the the site or the MOD-t printer utility to prompt you to “Press the front panel to begin printing” as this ensures your file has been completely transferred to the printer.

I do hope this helps but if you have any additional questions do not hesitate to reach out to us at

Thank You,

The New Matter Support Team
