3D Printing Calculator Toolkit

3D printing calculators, filament temperature charts and a print-defect guide — all offline, on your phone. No internet, no account, no sign-up. Dial in a new filament, calibrate your extruder, or rescue a failing print while you are standing at the machine. Every number is backed by a formula you can see. FILAMENT REFERENCE (free) Nozzle and bed temperature, part cooling, enclosure need, drying schedule, shrinkage and density for 12 filaments: PLA, PLA+, PETG, ABS, ASA, TPU, nylon, carbon-fibre nylon, polycarbonate, HIPS, PVA and wood-fill PLA. Each one also tells you what it is good for, what to watch out for, and which bed surface actually holds it. Abrasive filaments are flagged before they wear out your nozzle. CALCULATORS (all free) • Filament cost & weight — mass, volume and price per print • Filament left on a spool — weigh the spool, get the metres remaining • Flow / extrusion multiplier — correct it from a single-wall measurement • E-steps calibration — rescale your extruder steps/mm • Volumetric flow — check a speed against your hot end's limit • Max print speed — the fastest speed before under-extrusion • Retraction tuning — distance & speed starting points by extruder and material • Electricity cost — power use and cost per print • Solid layers — top/bottom layers for a target thickness • Resize / scale — scale a model to an exact dimension Every calculator shows the formula it uses and notes its assumptions — no black boxes, no false precision. Pick a filament and the calculator shows that material's temperatures alongside it. TROUBLESHOOTING (all free) Print defect → cause → fix for the eleven problems you actually hit: stringing, warping, under-extrusion, over-extrusion, layer shifting, elephant's foot, Z-banding, blobs & zits, ghosting / ringing, top pillowing and poor bridging. Causes are ordered most-likely-first, and honest about when several of them look alike. ACCURACY YOU CAN TRUST ✓ Formulas derived from first principles, shown in the app ✓ Temperatures are widely-published starting points, not invented specs — always defer to your spool ✓ Material densities are editable typical values, never fixed truth ✓ 100% offline — works at the printer, in the workshop, anywhere ✓ No account, no analytics, no clutter Prefer to read it on a big screen? The same filament chart and defect guide are free on the web: https://infinitxlabs.com/print3d/filament-settings/ https://infinitxlabs.com/print3d/troubleshooting/ PRO (optional, one-time) Everything above stays free, forever. Pro is for power users: • Save your own filament library (measured densities, prices) • Save printer profiles and load them into any calculator • Save and revisit calculation results • Remove ads Pro never paywalls a calculator, a temperature or a fix — only convenience features and ad removal. Spend less time digging through forums and more time printing. 3D Printing Toolkit keeps the numbers and the fixes one tap away.
