3D filament weight calculator

A decision is only as good as the number behind it. That is exactly what the 3D filament weight calculator is for — instant results, with the reasoning shown rather than hidden.

Don't expect the 3D filament weight calculator to read your mind. Two minutes spent checking your data saves you from wrong conclusions later.

What you're calculating

Whether costing filament for a print farm, toner for an office, or lead time for a job — the tool gives numbers ready for quoting or budgeting. Add electricity (~0.1 kWh/h × rate), printer amortisation, and a 30–50% margin for the client price. Compute before every job, keep an eye on monthly spend, and scale only when the numbers show a stable margin.

PLA 1.24 g/cm³) × infill; time ≈ path length / print speed. 3D filament weight calculation tool turns 3D printing or inkjet output from vague pricing into a concrete € sum per file, page or project.

Where income, tax or contributions are involved, the reference framework is Revenue and PRSI and USC — income tax 20/40%, USC 0.5–8%, VAT 23%.

The rule the tool follows

Common: ignoring failed prints (20–30% early on), warpage and support material. For a print farm, 3–5 printers is the profitability sweet spot. Buy filament in bulk (5+ kg) — price drops 30–40%. For toner, compatible/refurbished cartridges are 50–70% cheaper at ~95% quality.

Second: uncalibrated density — PLA rated 1.24 g/cm³ may in reality be 1.20–1.28 (±5% cost). Third: for inkjet, quoting cartridge price without real page yield (typically 80% of advertised). For an office: laser beats inkjet long-term (2–3× cheaper per page).

When it makes sense to reach for this

Figures use euros, metric units and Revenue defaults where applicable. Weight of model + support + brim × price/kg + electricity (0.1 kWh/h) + amortisation (printer / total life hours) + margin. Laser: faster, cheaper per page, more dependable under light use. Slicers estimate ±10% off actual weight.

How to get a number you can trust

3D filament weight calculation tool gives the numbers so you don't misprice and can optimise costs. This 3D filament weight calculator is tuned to practice in Ireland: amounts are shown in euro (EUR, €), formatted as €1,234.56, and quantities use fully metric (km, kg, °C, L). That means the output can be used directly with an accountant, lender or employer in Ireland without converting anything.

Recalculate after changing one input at a time; this shows which assumption controls the calculated figure and makes an unexpected answer easier to diagnose. Print — 3D or paper — is a details business.

The cleanest way to learn this is to see it done once.

The classic traps

For Ireland, use the units printed beside each field and do not assume that a familiar name means the same measurement system. Inkjet: cost per page = (cartridge cost / pages per cartridge) + paper.

Example: a 3D model with 100 g of PLA and 2.63 hours at 0.62 €/kg gives direct cost. Every figure above applies to Ireland specifically and is reviewed when the rules change.

What seasoned users do differently

Start by checking the input fields rather than the final number. First 6–12 months typically operate at a loss for training, waste and customer acquisition.

Ireland uses the euro and metric units, so 3D filament weight calculator follows Revenue's framework rather than UK figures. Over 500 pages/month: always laser.

When this number matters

• Currency & format: Euro (EUR, €). Decimal comma typical in official documents.
• Electrical supply: 230 V / 50 Hz, Type G plug (same as UK).
• Local notes: Figures use euros, metric units and Revenue defaults where applicable.
• Units of assess: Fully metric. Older generation may still speak in miles or stones informally.
• VAT / sales tax: Ireland's standard VAT is 23%. Reduced rates: 13.5% (hospitality, hairdressing, building), 9% (newspapers, e-books), 0% (most food, children's clothing, books).
