TrestleFDM grows sturdy filament trees under your miniature and lets them touch it only through a fine resin-style tip. They hold every overhang and snap off with a tiny mark. Export a 3MF and print it in any slicer.
Instant download · No install · Works with Bambu Studio, OrcaSlicer, PrusaSlicer and Cura
FDM supports are strong but leave scars. Resin supports leave tiny marks but snap on a filament printer. TrestleFDM combines the two.
Strong, but wide contact areas leave rough patches on faces, fingers and hair.
Tiny marks, but long thin pins break as soon as the nozzle brushes them.
Thick filament trunks and branches, and only the last fraction of a millimetre is a fine tip.
Every default was measured on real slicer G-code and test prints, not guessed.
Branches merge into trunks that thicken as they descend, on wide feet that do not snap at the base. Only the tip is thin.
The print is simulated layer by layer to find islands, hanging edges, corners of flat faces and the bottom line of arms and legs. You get the fewest contacts that still print clean.
Inside a mouth, between teeth or under a chin, a support can stand on the model. It ends on a fine tip too, so it leaves only a small mark.
Left click to add a point and right click to remove one, with a live preview of the pin. Undo and redo cover every step.
Find the best face to lay the model on, rotate it with handles, scale it in mm or %, and repair broken meshes in one click.
Exports one 3MF with the model, supports and raft. In Bambu Studio and OrcaSlicer the supports bring their own print settings. Opens in PrusaSlicer and Cura too.
Open a model, generate, and check every support in a fast 3D viewer that handles millions of triangles.
A closer look at what TrestleFDM does for you, and what you can control.
FDM prints fail first at the edges: the outer wall of a layer reaching over nothing. TrestleFDM slices your model layer by layer, finds every hanging edge and corner, and puts contacts right on them, with an even spread across flat faces.
Every contact gets a fine tip, the tips merge into branches and the branches into thick trunks on wide feet. Flat shelves, round discs and long overhangs all get the same treatment.
Turn on Show contact dots to see each point colour-coded by the reason it was placed, with a key and a count for every colour. Points that are not needed are left out, so you get clean prints with fewer marks.
The Basic tab covers what most prints need: overhang angle, density, trunk thickness, raft, braces and whether supports may stand on the model. Manual points only lets you place every contact yourself.
The Advanced tab opens every engine setting, from tip size and pin length to branch angle, foot size and raft margins. Changed values turn amber, and one click resets them.
No Blender, no add-ons, no setup. Unzip and run.
STL, OBJ or 3MF. Pick the 0.2 or 0.4 mm nozzle preset and a density: Light, Normal or Dense.
Usually seconds, even on detailed miniatures. Add or remove points by hand if you want.
Export a 3MF, or open it straight in Bambu Studio, OrcaSlicer, PrusaSlicer or Cura. Keep the slicer's own supports off.
If a spot would print in the air, TrestleFDM marks it in red and tells you why. Some spots can only be held by a support standing on the model, and the status bar offers to fix them in one click.
US$7 minimum, one-time. Pay more if you want to support development.

No. TrestleFDM is a standalone Windows program. It only needs your slicer to print the file it exports.
Any slicer that opens 3MF or STL. It is tested with Bambu Studio, OrcaSlicer, PrusaSlicer and UltiMaker Cura. In Bambu Studio and OrcaSlicer the supports and raft also bring their own print settings. Turn off the slicer's own supports, because the supports are already in the file.
Yes. Pick the 0.4 preset and TrestleFDM sizes the tips and the layer check for that nozzle (0.12 mm layers by default). The 0.2 preset is for the finest miniatures.
Windows 10 or 11. There is nothing to install: unzip and run TrestleFDM.exe. A graphics card makes the viewer smoother, but it is not required.
Not yet. TrestleFDM is Windows only for now.
The support engine is tested on real prints and real slicer G-code, but this is the first public release. If something does not work on your model, email me and I will look at it.
