search | Search everything on PrintPal for a 3D-printing query: community 3D models, free tools and calculators, wiki troubleshooting articles, OpenSCAD/AI-CAD docs, video tutorials, build guides and Academy courses. Returns ids accepted by `fetch` for the full content. Suited to general 3D printing question |
fetch | Fetch the full content of a PrintPal item returned by `search` (or any id of the form `model:<uid>`, `tool:<slug>`, `wiki:<slug>`, `doc:<slug>`, `resource:<slug>`, `project:<slug>`, `course:<slug>`). Returns the complete text (article body, transcript, build steps, BOM, model description and files) |
search_3d_models | Find printable 3D models (STL/3MF/OBJ) in the PrintPal community library by keyword — e.g. "articulated dragon", "headphone stand", "Raspberry Pi 5 case". Returns cards with thumbnail, author, tags, likes and a link to the model page where the files can be downloaded. Searches existing uploads only; |
get_3d_model | Get full details for one PrintPal model by uid: description, license, file formats, author, stats, and the page URL to download it. Accepts a uid from `search_3d_models` results or a printpal.io/model/<uid> URL. |
find_3d_printing_tool | Recommend the right free PrintPal browser tool for a task: print cost / resin cost / layer height (magic numbers) / E-steps / flow rate / volumetric flow / filament spool / drying / shrinkage / Vref / Etsy profit calculators; generators for lithophanes, vases, name plates, 3D text, QR codes, bins, p |
calculate_print_cost | Estimate what an FDM print costs (material, electricity, machine wear, labor, failure allowance) and a suggested selling price. Needs the print weight in grams and time in hours from the slicer; all other inputs have sensible defaults (1 kg spool at $20, 120 W printer, $0.12/kWh, 5% failures). |
calculate_filament_usage | Convert filament grams to metres (and back), compute volume and cost, and estimate how much is left on a spool from its gross weight. Knows densities for PLA, PETG, ABS, ASA, TPU, Nylon, PC, CF blends. Give either `grams` or `meters`. |
calculate_layer_heights | Compute the Z-axis "magic number" layer heights for a printer from its stepper step angle, microstepping and lead-screw pitch/starts, filtered to what suits the nozzle. Defaults match most Ender/Prusa-style printers (1.8°, 1/16, T8 2 mm × 4 starts → 0.04 mm steps). |
calculate_volumetric_flow | Check whether a hotend can keep up: volumetric flow (mm³/s) = layer height × line width × speed, compared against the hotend limit, plus the maximum safe speed. Accepts a hotend preset name (stock, v6, bambu, volcano, rapido, high-flow, goliath…) or an explicit max flow. |
search_build_guides | Find step-by-step PrintPal build guides: Arduino/ESP32 electronics + 3D-printed enclosures, robots, functional prints, printer mods, STEM classroom projects, props and toys. Each result lists difficulty, time, cost, part/file/step counts. Filter by category (electronics-robotics, functional-prints, |
get_build_guide | Read a full PrintPal build guide by slug: summary, bill of materials with quantities and links, downloadable files (STL/3MF/code), every build step, callouts and code blocks. Use when the user wants to actually follow or adapt a project. |
search_learning_resources | Search PrintPal's how-to content: the vendor-neutral 3D printing wiki (print quality, filaments, slicer settings, maintenance, error codes, safety), OpenSCAD + AI-CAD docs, short video tutorials with transcripts, and free Academy courses with certificates. Use `type` to narrow. Results include ids a |
generate_3d_model | Turn a text prompt or an image into a print-ready 3D mesh (STL/GLB/OBJ geometry) with PrintPal's AI generator. Without a PrintPal API key this returns a link that opens the generator on printpal.io with the prompt prefilled; nothing is generated until the user clicks it. With an API key header (`Aut |
check_3d_generation | Poll a PrintPal AI generation started with `generate_3d_model` in API-key mode. Returns status (queued/processing/completed/failed) and, when completed, a time-limited download URL for the mesh. |
design_parametric_cad | For mechanical / functional parts with exact dimensions — brackets, enclosures, adapters, gears, bins, knobs, mounts — open PrintPal's AI CAD agent with a ready-to-run brief. The agent writes editable OpenSCAD with parameter sliders, live 3D preview and STL/3MF/STEP export. This tool improves the us |
get_pricing_and_plans | Explain what is free on PrintPal, how AI generation credits and the CAD agent are priced, API access and the on-demand 3D printing service — with links to sign up, buy credits or subscribe. Call when the user asks about cost, limits, subscriptions or how to get more generations. |
