How it works

Three steps from model to wall art

No setup, no upload, no waiting. Drop a file in and start slicing.

1

Upload a model

Drop in any 3D model you already have. SliceForge reads it locally and shows it on the stage instantly.

2

Slice & shape

Set orientation, cut direction, thickness and gap; add a keep-depth front relief, then design the backboard it mounts to.

Export & print

Download a combined STL or a multi-body 3MF, print the layers, then stack them onto the board.

What you can make

Layered relief, from almost anything

Animal busts, helmets, portraits, logos — if you have the model, you can stack it.

FAQ

Questions, answered

What is a layered (contour-slice) sculpture?
A 3D form rebuilt from many thin parallel slabs mounted on a backboard, creating a stacked relief — popular as 3D-printed wall art.
Which file formats can I import?
STL, OBJ, 3MF and PLY.
Is it really free? Do I need an account?
Yes, free, and no signup. It runs entirely in your browser.
Do my models get uploaded anywhere?
No. All slicing and exporting happen locally in your browser; nothing is sent to a server.
What can I export?
A combined STL, or a multi-body 3MF with each slice and the backboard as separate solids.
What can I make with it?
Layered wall art: animal heads, helmets, portraits, logos, terrain — anything you have a 3D model of.
