Hi there, after downloading the STL format from online, you can upload the models files to the Poloprint app.
Before uploading, please make sure your printer is connected to the wifi and the app. Then you could go to “Me>Profile” on the APP and you will see a “+” option in the bottom left corner of the page.Then you could upload your own STL format models files to the app and try to print. Thanks.
