Overview

AI-generated overview

PrintPal gives an assistant 3D-printing knowledge and calculators: model search, build guides, troubleshooting wiki, print math, and optional AI 3D/CAD…

What you can do
  • Search and fetch PrintPal content: models, tools, wiki articles, docs, guides, courses
  • Find and read printable 3D models with details, license and download page
  • Recommend PrintPal browser tools and run print math: cost, filament usage, layer heights, volumetric flow
  • Search and read step-by-step build guides with bills of materials and files
  • Search learning resources: wiki, OpenSCAD/AI-CAD docs, video tutorials, Academy courses
  • Generate 3D meshes from text or images, poll generation status, and open the AI CAD agent; explain pricing and plans
When to use it
Useful when a user asks 3D-printing questions, needs a printable model or build guide, wants print cost or slicer math, or wants to design a part or generate a mesh. The search, calculator and knowledge tools work without an account.
Requirements
Remote MCP endpoint at printpal.io over streamable HTTP; no local install. No authentication is required for search, calculator and knowledge tools. AI 3D generation and CAD agent use require an optional Authorization header with a PrintPal API key.
Before you install
The optional Authorization header carries a PrintPal API key; keep it private. AI generation is credit-metered and paid, and pricing tools link to purchases. Generation without a key only opens a prefilled page. Model and guide results link to third-party downloads.

Installation

In SourceWeft

  1. Open PrintPal in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.printpal%2Fprintpal/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

fetch

Fetch a PrintPal item

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) plus the canonical URL for citation.

Parametersidrequired

search_3d_models

Search 3D models to print

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; new models are made by `generate_3d_model` (AI mesh) or `design_parametric_cad` (exact dimensions).

Parameterslimitqueryrequiredcategory

get_3d_model

Get 3D model details

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.

Parametersuidrequired

find_3d_printing_tool

Find a PrintPal tool or calculator

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, puzzles, mold boxes, flexi models, fidget clickers, Desk Pal, terrain maps, Minecraft maps; mesh repair, model splitter, converter, viewer, G-code viewer, AMS/multicolor painters; AI generators. Returns matching tools with links. Pass an empty task to list every tool.

Parameterstasklimit

calculate_print_cost

Calculate 3D 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

Filament weight ⇄ length ⇄ cost

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

Layer height magic numbers

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).

Parametersmicrosteppinglead_screw_startsnozzle_diameter_mmstep_angle_degreeslead_screw_pitch_mmmax_layer_height_mm

calculate_volumetric_flow

Volumetric flow / max speed check

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

Search build guides & projects

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, home-workshop, stem-education, printer-mods, art-props, toys-games) or difficulty (beginner, intermediate, advanced). Leave query empty to browse featured guides.

get_build_guide

Get a build guide (steps, BOM, files)

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.

Parametersslugrequired

search_learning_resources

Search guides, videos & courses

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 accepted by `fetch` for the full article text.

Parameterstypelimitqueryrequired

generate_3d_model

Generate a 3D model with AI (text or image → STL/GLB/OBJ)

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 (`Authorization: Bearer pp_live_…`) it submits the job to the user's own account, spends that account's credits, and returns a `generation_uid` that `check_3d_generation` accepts. Suited to organic/sculptural objects (figurines, animals, props); exact-dimension mechanical parts are handled by `design_parametric_cad`.

Parametersformatpromptrequiredqualityimage_url

check_3d_generation

Check AI 3D generation status / get download

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.

Parametersgeneration_uidrequired

design_parametric_cad

Design a parametric part with the AI CAD agent

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 user's description into a precise CAD brief (dimensions, tolerances, mounting, print orientation) and returns the link; the user clicks it to generate.

Parametersmaterialdimensionsdescriptionrequiredexport_format

get_pricing_and_plans

PrintPal pricing, credits & 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.
