Workshop & 3D Printing
Calculators for 3D printing, CNC and laser: filament, print cost, calibration and cutting data.
CNC Feeds & Speeds CalculatorCalculate spindle speed and feed rate for milling from tool diameter, flutes, cutting speed and chip load – or check your machine settings.3D Print Dimension CalibrationMake 3D prints dimensionally accurate: scale per axis from a measured calibration cube, and the compensation for holes that come out too small.Extruder Calibration (E-steps & Flow)Calibrate your 3D printer’s extruder: new E-steps for Marlin or rotation_distance for Klipper from a 100 mm test, and the flow rate from a measured wall.Filament CalculatorConvert 3D printing filament between weight, length and cost for PLA, PETG, ABS, TPU and more – and find out how much is left on a spool.Filament GuidePrint settings for PLA, PETG, ABS, ASA, TPU, nylon, PC and more at a glance: nozzle and bed temperature, fan, enclosure, drying and density.G-code AnalyzerAnalyse G-code from Cura, PrusaSlicer, OrcaSlicer & co.: print time, filament in m and g, layers, print size and a layer-by-layer path preview.Gear GeneratorCreate involute spur gears and gear pairs as SVG or DXF for laser cutters, CNC and 3D printing – with centre distance, ratio, bore and backlash.Kerf CalculatorMeasure the kerf of your laser cutter or CNC from a test cut and get the sizes to draw for parts, holes, slots and press fits.Laser Box GeneratorGenerate a finger-jointed box for laser cutters and CNC as SVG: inside or outside dimensions, material thickness, lid and kerf compensation.Image for Laser EngravingPrepare photos and graphics for laser engraving: set size in mm and dpi, adjust contrast and dither with Floyd–Steinberg, Atkinson & more – in your browser.Laser Test Grid GeneratorCreate a power and speed test grid for your laser engraver as G-code for GRBL, with labels and preview – find the right settings for any material.3D Print Cost CalculatorCalculate what a 3D print really costs: filament, electricity, printer wear, failed prints, working time and markup – for the whole job and per part.Steps per mm CalculatorSteps per mm for belt and lead screw axes of 3D printers, CNC machines and lasers – incl. Klipper rotation_distance and layer heights without rounding.STL Viewer & AnalysisView STL files in 3D and measure them: dimensions, volume, surface, holes and flipped normals, plus a filament and weight estimate – without uploading.Thread Chart & Tap DrillTap drill, clearance holes, pitch and core diameters for metric coarse and fine threads and UNC/UNF – for any metric size, too.Volumetric Flow CalculatorCalculate the volumetric flow in mm³/s from print speed, layer height and line width – or the highest print speed your hot end can melt for.
