Tutorial 1: Your First Fabric Stack

Fabric Sculpt turns 2D line generators into stacked extrusion G-code. Unlike G-code Sculptor (a height–radius profile) or Mesh Sculptor (an STL), this module fits a line pattern to your bed and stacks it in Z.

What you'll learn

How to open Fabric Sculpt from the empty canvas
How to pick a generator and optional filter
How stack options and the Print tab affect the preview
How to download G-code for a direct print

Prerequisites

Open 3dSynth in the browser or desktop app
A printer preset whose bed size matches the machine you will use (Fabric Sculpt fits the pattern to that rectangle)

Step 1: Open Fabric Sculpt

Step 1

Add the module

From the empty canvas, click the Fabric Sculpt card (or use the sidebar + and pick Fabric Sculpt). The left dock switches to Pattern and Print.

Step 2: Pick a generator

Step 2

Choose parallel-lines or fabric-weave

In Pattern, open Generator and choose parallel-lines or fabric-weave. Leave numeric fields at their defaults for the first print. The preview regenerates after a short debounce.

Step 3: Optional filter

Step 3

Add a filter only if you want a comparison

Under Filters, you can Add filter (for example corner-rounding or noise-displacement). Toggle the filter’s checkbox off to compare before and after. Use Remove if you do not want it. Skip this step for a first stack.

Step 4: Stack options

Step 4

Set a visible layer count

In Stack (G-code), set Layers to 40–80 so the stack is easy to see. Try Alternate layer rotation at 15–45 degrees if you want shifted layers. Use Z offset only when you need a first-layer vertical nudge.

Step 5: Printer presets and bed fit

Step 5

Confirm the bed

Open the Print tab and confirm bed dimensions match your machine. Fabric Sculpt scales the XY pattern to fit this bed (with margin).

Step 6: Preview and export

Step 6

Inspect, then download

Use the viewport layer / height controls to inspect a band of layers. When the preview looks right, use Download G-code from the toolbar. The filename prefix follows the Fabric Sculpt module type.

Outcome

You should see a 3D toolpath of the stacked pattern and a downloadable .gcode file tuned to your Print preset.
