01 / PREPARE
Fine-tune every layer
Layer height, walls, infill, supports, temperatures, ironing, fuzzy skin and settings that change by height. Keep it simple or open the advanced controls.
Windows & Mac beta opens mid-November
From idea
to first layer.
A capable 3D printing slicer and part designer for the devices you already own. Prepare a model, tune every detail and send it to your printer from your phone, tablet or computer.
WrenSlicer is in development. Features and availability may change before release.
One app, every screen
Made for the device
in front of you.
The same plate, settings and tools on iPhone, iPad, Android, Mac and Windows: a bottom bar and big targets on phones, a sidebar and keyboard shortcuts on bigger screens.
Screens are drawn by the app itself from development builds. Phone and tablet layouts are rendered at device size; the finished apps may differ.

Make it yours
More control.
Less setup.
Start with the model you have. Arrange it on the plate, shape it to fit, and choose the settings that matter to your print.
02 / ARRANGE
Make the plate work
Move, rotate, copy and arrange models. Put a better face down, split a part, or open every model in a .zip at once.
03 / CONNECT
Get to your printer
Send over Wi-Fi to Bambu Lab, Elegoo, Creality, Flashforge, Anycubic, Klipper and more, print over USB from a computer, or save to a card.
04 / DESIGN
Design real parts
Editable templates become true 3D solids: holes and hole patterns, chamfers, fillets, raised or engraved text.
05 / CHECK
Know before you print
Preview every layer, get a quick strength estimate, run calibration prints and keep a history with notes and ratings.
IN DEVELOPMENT / AI DESIGN
From a photo or sketch to a 3D part
Snap a broken part or draw what you need, add a measurement, and get an editable design. Tracing an outline from a photo works offline; AI design needs a connection.
