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.

@Lynze-Myers Hi there, please go to "Me>Profile>Settings" on the app to sign out and sign in again.

If the problem persists, you can try uninstalling the app, clearing its cache, reinstalling it, and logging in again.

If the problem still exists, please contact our support team, and we will help you resolve the issue as soon as possible. Thanks.

@Sasha-0 Hi there, so sorry that we are not sure your meaning. Is there a model that is being uploaded and you don't want to print it? If so, you can simply turn off the machine power, and the model will stop being uploaded to the printer and will not be printed.

If what we say is not what you mean, please tell us more details. Thanks.

@Jacqueline-Grace Hi there. Before uploading the STL file to the APP, please make sure your printer is connected to the APP and the WIFI.

And please kindly note that after binding the device, you will get 500MB of storage space to store your own models. 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 to print.

If you want to slice the models in the Willbuilder, you could check below tutorial video.

@Marc-2 Hi there, because the Tina 2 Plus machine does not support PETG filament, PETG is not displayed as a printing option. However, it does support PLA and TPU filaments, which you can try printing with.

If you have any questions, please feel free to contact us.

@Christian-Dosson Hello, are you referring to the storage containers that hangs on the side of the machine to hold small tools? It would be helpful if you could provide more details.Thanks.

@3D-Printer-Guy Hi there, you could go to the app and choose the models you want to print, and select "print>custom>supprt type" on the app, then you can change the supports as you need.

@johnboi7-watmough You could go to this website thingiverseand download STL model files or design your own model using modelling software and output it in STL format, then use Wiibuilder to slice STL to Gcode file, then save to TF card or use WiFi upload printing.

About the slicer software using, here are some video guide of how to use Wiibuilder, hope it helps you.

For the printer with wifi function, you can also use Poloprint Cloua app to print via your phone or iPad. After binding the device, you will get 500MB of storage space to store your own models. 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.

@James-p Hello, the purpose of supports is to hold up the suspended parts and prevent them from collapsing or deforming during printing. Tree-shaped supports are easier to remove from the model than ordinary supports.
