3D Printing Tools

A collection of free, useful tools to help you get the most out of your 3D printer.

CAD AI Modeling

Describe a mechanical part and get a dimensionally accurate model. Threads, tolerances, and standard hardware sizes are handled for you.

Organic AI Modeling

Characters, figurines, and freeform shapes. Colors are automatically separated into shells for multi-color printing.

Calculators

New

Thread & Tap Size Calculator

Find the correct drying temperature and time for PLA, PETG, ABS, TPU, Nylon and more.

New

Acceleration Distance Calculator

Calculate the distance required for your printer to reach full speed given your acceleration settings.

New

Material Shrinkage Calculator

Calculate the scaling factor to compensate for material shrinkage. Presets for PLA, ABS, ASA, PETG, Nylon, PC, PP, and more.

New

Filament Density Converter

Convert between filament length (meters) and weight (grams) for any material density.

Free

3D Print Cost Calculator

Calculate the exact cost of your 3D prints including filament weight, electricity usage, and machine wear.

New

Resin Print Cost Calculator

Calculate the true cost of resin 3D prints including resin, electricity, consumables, and failure rate markup.

New

Volumetric Flow Calculator

Calculate the volumetric flow (mm³/s) to ensure you don't exceed your hotend's max melting speed.

Free

Filament Spool Calculator

Estimate how much filament you have left by weighing your spool. Database of common brands included.

Free

E-Steps Calculator

Calibrate your extruder's E-Steps value to fix under-extrusion or over-extrusion issues.

New

Flow Rate Calculator

Calibrate your extrusion multiplier (flow rate) for dimensionally accurate walls and solid top layers.

New

Layer Height Calculator

Find the optimal 'magic number' layer heights for your 3D printer to reduce Z-wobble and improve print quality.
