What it can do
| Tool | What it says it does |
|---|---|
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_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_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. |
check_3d_generation | Check a generation started with generate_3d_model on the connected PrintPal account: status (processing, completed, failed or stalled), credit accounting, and when completed a fresh download link (valid 1 hour) for the actual delivered file. Never starts or charges a generation. Poll at the… |
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… |
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… |
generate_3d_model | Step 2 of AI 3D generation. Starts the job priced by prepare_3d_generation on the user's connected PrintPal account and spends the quoted credits. Call only after the user has agreed to the cost shown by prepare_3d_generation, passing its quote_token and the approved credit amount. Pass a stable… |
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. |
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. |
get_printpal_profile | Return the PrintPal profile represented by this request's authenticated credentials. The opaque id is unique within this app and remains unchanged across token refresh, reconnection, and display-name changes. |
open_3d_generator_link | Build a printpal.io link that opens the AI 3D generator with a prompt prefilled, for users who want to generate on the website themselves. This tool does not generate anything, does not use credits and does not mean a model exists. When the user wants the model made here, use prepare_3d_generation… |
open_cad_agent_link | Build a printpal.io link that opens the PrintPal AI CAD agent with a design brief prefilled, for users who want to design a functional part with exact dimensions (a bracket, enclosure, adapter or mount) on the website. The brief combines the description, dimensions and material given here with… |
prepare_3d_generation | Step 1 of AI 3D generation on the user's connected PrintPal account. Validates the prompt or attached image, quality and format, and returns the exact credit cost, the account's available credits, normalised settings and a short-lived quote_token. Nothing is generated or charged. Show the user the… |
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… |
search_3d_models | Find free 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… |
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… |
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… |
