SpeakCAD for the Bambu Lab P1S
Custom parts for the Bambu Lab P1S: describe them, download a .gcode.3mf sliced for it
The enclosed CoreXY Bambu with a 256 x 256 x 250 mm volume and the AMS, at home with PETG and ABS. SpeakCAD ships the Bambu Lab P1S's own OrcaSlicer profile: describe a part in plain English, watch it render on a virtual 256 x 256 mm bed, edit it by chat, and download a sliced .gcode.3mf, the file Bambu printers read from the microSD card and that Bambu Studio sends over the network. Or take the STL or 3MF to your usual slicer. Runs in Safari and Chrome, on a phone or a computer, nothing to install.
How it works
From a sentence to the P1S's microSD card
The slicer runs on our side with the same profiles OrcaSlicer ships for the Bambu Lab P1S. You choose the print profile and the filament; the printer settings are already right.2
Check it on the P1S's bed
The part renders on a virtual bed the size of the P1S's. The first render usually appears within a minute or two: a new part goes to the strongest models, which reason through the geometry, and small edits land in seconds. Turn it, tap a face to read a size, open the dimensions panel, and see whether it has overhangs that need supports. Anything wrong is one sentence to fix.3
Pick the Bambu Lab P1S and its profile
In the download dialog choose the Bambu Lab P1S (0.2 nozzle, 0.4 nozzle, 0.6 nozzle, 0.8 nozzle), one of its print profiles (0.06 mm, 0.08 mm, 0.1 mm, 0.12 mm…), a filament, then infill, walls, supports and adhesion. The printer and its last settings are saved to your account.4
Download and print
You get a sliced .gcode.3mf, the file Bambu printers read from the microSD card and that Bambu Studio sends over the network, with the estimated print time and filament weight. Re-slicing a design you already downloaded does not spend the 10 credits again; without Pro or Unlimited each slice still spends 5 credits.The Bambu Lab P1S profile SpeakCAD slices with

Prompts sized for the P1S
Copy one, change the numbers to yours. Each opens in the editor with the text already typed.“A poop chute extension for a Bambu Lab P1S: fits the rear waste opening, 60 mm wide channel angled 30 degrees into a 100 x 80 x 120 mm bin with a removable front, 2 mm walls.”
Open this prompt in the editor“A glass door handle for a P1S: 90 mm long, 20 mm stand-off, clips over a 3 mm glass edge with 0.2 mm clearance, rounded grip, printed in ABS.”
Open this prompt in the editor“A Raspberry Pi 5 case with a 30 mm fan grille, GPIO ribbon slot and two keyhole wall mounts, 2 mm walls, screwed lid with M2.5 pillars.”

Slicing is the step that keeps 3D printing on the desktop: a design made anywhere still has to pass through Bambu Studio, PrusaSlicer or Cura on a computer. SpeakCAD runs OrcaSlicer on its own servers with the profile OrcaSlicer ships for the Bambu Lab P1S, so the phone that typed the description also downloads a .gcode.3mf. The desktop slicer stays the better choice for arranging many parts on one bed or for exotic settings; for one part at a time, the download dialog covers the profile, the filament, infill, walls, supports and adhesion.
Parts that fit the P1S
The Bambu Lab P1S's 256 x 256 mm bed and 250 mm height are what the virtual bed in the viewer shows, so a part that looks too big is too big. Ask for a part to be split into two halves with alignment pins when it does not fit, or for a flat print orientation when it would need supports. The examples above and the library parts below all fit.
Parts that fit the first time
The Bambu Lab P1S prints slightly differently from the next printer, which is why holes come out tight and lids loose. Fit Check cuts a five-minute test slice from the interface that must fit, you report too tight, perfect or too loose, and every model after that is built with the clearance your P1S needs. The test slice downloads free as STL or 3MF. How Fit Check works.

Questions
Yes. The Bambu Lab P1S is one of the 380+ printers in the slicer catalog, with 4 nozzle variants and the print and filament profiles OrcaSlicer ships for it. Pick it in the download dialog and download a .gcode.3mf; it is saved to your account for next time.
No. SpeakCAD slices on its servers and gives you a .gcode.3mf. Copy it to the P1S's microSD card and start it from the printer's screen, or open it in Bambu Studio and send it over the network. If you prefer your own slicer, download the STL or 3MF instead.
The print profile (layer height and speed presets from the Bambu Lab P1S's profile), the filament profile (the printer's own and the OrcaSlicer library: Generic PLA, PETG, ABS, ASA, TPU, carbon-fibre blends and hundreds of branded filaments), infill, wall count, supports and bed adhesion. Nozzle temperature, bed temperature and speeds come from the profiles you pick.
The virtual bed in the viewer is sized from the Bambu Lab P1S's profile (256 x 256 mm), so you see it before slicing. Ask for the part to be split into two pieces with alignment pins or a dovetail, or for a different orientation; each is one sentence.
Sliced downloads are included in Pro ($9.99 a month, 200 credits) and Unlimited ($24.99 a month); with Starter credits ($5 once for 75 credits, no subscription) a sliced download spends 5 credits on top of the usual 10. Re-slicing a design you already downloaded does not spend the 10 credits again; without Pro or Unlimited each slice still spends 5 credits. STL and 3MF downloads are always available.
Yes. The editor runs in Safari on iPhone and iPad and in Chrome on Android; the file lands in Files or Downloads, ready for the card or the printer's app. The same project opens later on a desktop.
