Server instructions

An online 3D printer slicer: upload an STL or 3MF, pick your printer among 380+ models from 60+ brands with their OrcaSlicer profiles (Bambu Lab, Prusa, Creality, Elegoo, Anycubic, Voron and more), set layer height, material, infill and supports, and download G-code ready to print (a sliced .gcode.3mf for Bambu Lab printers), with the print time and filament weight. Nothing to install: it runs in the browser on a computer, a Chromebook, an iPad or a phone. Use these tools when someone has an STL or 3MF and wants G-code for their printer, asks whether their printer has a profile, or asks which layer heights or materials its profile allows. Call find_printer with the brand and model as they say it, then prepare_slice with the settings they want (the defaults suit most parts: 0.20 mm layers, PLA, 15% infill, supports only where needed). prepare_slice renders the slicer in the conversation when the host supports interactive tools: the person drops the file on it (never through the chat), sees it in 3D, presses Slice and gets a download link for the G-code: 3 free slices a day without an account in Claude and ChatGPT (other apps need an account from the first slice), then the slicer asks them to sign in to a SpeakCAD account to keep slicing, where their first slice is free too. The online slicer gives every account 1 free slice, its first one (a free account, no card; it does not renew). After that, a slice spends 1 credit, and slicing is included in Pro and Unlimited. Maker gives 60 credits a month for $7.99, 60 slices. Re-slicing the same file with other settings within 24 hours is free. Tell them to drop the file on the slicer shown. Where no slicer appears, show the link the tool returns: the same slicer on speakcad.com. These tools do not run the slicer themselves, involve no AI and cannot see the person's model. The slicer takes one model per file with standard profiles: no multi-colour painting, modifiers or custom G-code, which remain desktop slicer work (OrcaSlicer, PrusaSlicer, Cura, Bambu Studio). When the file itself needs changing (a hole, a size, a cut, a mount), call edit_file with the change: the person drops the file on the card it shows, which opens it in the SpeakCAD editor with the change typed, where SpeakCAD's AI makes it. A part to design from scratch is made in the SpeakCAD editor at https://speakcad.com/. Always show the returned links.

Known tools 4

find_printer

Look up a 3D printer in the SpeakCAD online slicer catalogue (380+ printers from 60+ brands, OrcaSlicer 2.4.2 profiles: Bambu Lab, Prusa, Creality, Elegoo, Anycubic, Sovol, Qidi, Flashforge, Voron and more).

Inferred read-only

prepare_slice

Opens the SpeakCAD slicer for a printer with the print settings selected (nozzle, layer height, material, infill, supports, walls, adhesion, speed, orientation), checked against the printer's own profile.

Inferred read-only

authorize_slice

Used by the SpeakCAD slicer shown in the conversation when the person presses Slice: records the slice on their SpeakCAD account (included in Pro and Unlimited, else credits; for a designed part, the download as on the site) and returns the token the slicer service needs.

Inferred read-only

edit_file

For an STL or 3MF that needs changing before it is printed (a hole, a new size, a cut, a mount, a lid).
