Opportunity snapshot
3D Print Cost Calculator is a free tool for people who sell or give away 3D prints and want to know what a print really costs. You enter the filament, print time, printer power draw, printer price, failure rate and your own time, and it returns the cost of the print and a suggested selling price. It is an idea report: the tool is not built, and this page gives the research, the verdict and a free build prompt so anyone can build it.

Executive summary
SIGNAL: keyword research on 18 October 2026 (KWS Everywhere bulk analysis) found these monthly volumes. 3d print cost calculator 2,900 (up 75%), 3d printing cost calculator 2,900 and 3d printing cost estimator 2,900 (both the same figure, so one body of demand with three wordings), 3d print pricing calculator 1,600 (up 96%), 3d printing price calculator 1,600 (same figure), how to price 3d prints 480 (stable), filament cost calculator 480 (down 18%), 3d print cost per gram 40 (down 67%), 3d print service pricing 50, how much to charge for 3d printing 50. Counting the shared figures once, that is roughly 4,500 searches a month. Searches for the main phrase have risen from 590 in October 2022 to a peak of 4,400 this summer, and were 2,900 in September 2026. The average cost per click is $2.64 for the main phrase and $1.90 for the pricing phrase, and the competition score is low (0.06 and 0.10).
SIGNAL: the seller-shaped searches are almost empty. Etsy 3d printing pricing, 3d printing markup, 3d printing electricity cost calculator, 3d printing business calculator and print farm profit calculator all returned zero. 3d print profit calculator returned 30, 3d printing hourly rate 30, 3d printing quote calculator 30. The searchers are mostly asking “what does this print cost me”, not “how do I run a print business”.
SIGNAL: a web search for the main phrase on 18 October 2026 returned PrintPal, Raspberry.tips, Fabbaloo, 3DWithUs, a Firefox add-on, a Chrome extension, a phone app, and a roundup naming Omni Calculator and Prusa’s calculator. The pages described cover filament, electricity, machine wear, a failure allowance and labour. A second search for failed prints and post-processing found more of the same: guides from printer makers that describe the same cost method, and tools such as a Chrome extension and an Etsy-focused spreadsheet.
ASSUMPTION: a calculator that is also clear about what it leaves out (design time, shipping, marketplace fees) and shows its arithmetic step by step can still earn a place against these. That is untested, and the competitors’ hidden-cost coverage means it cannot be the wedge on its own.
Where this idea came from: Reddit could not be reached, and mining 110 WordPress.org plugins and 592 Shopify apps for low-star complaints did not surface it. It came from a keyword screen of candidate niches (3D print sellers, streamers, mobile trades), where it was the only one with real volume. It is a demand-led pick, not a pain-led one.
The problem: prints that cost more than they sell for
A 3D print has several costs besides the plastic. The guides read for this report agree on the main ones: filament, electricity, wear on the printer, a share of prints that fail, and the time spent removing supports and finishing. One guide says the filament is often under a third of the true cost. Another notes that print time does not scale in a straight line with quantity, because a full build plate lowers the machine time per piece.
People who skip those costs underprice. People who include them need a spreadsheet or a calculator, and the guides say many calculators multiply grams by spool price and stop there.
The tool
The tool would be a single browser page. It would take the filament price per kilogram, grams used, print hours, the printer’s average power draw in watts, the electricity price per kilowatt-hour, the printer price and expected lifetime hours, a failure allowance in percent, minutes of hands-on finishing and an hourly rate for your time. It would return the cost of each part, a total, and a selling price from a margin you choose, with an optional marketplace fee. Everything would run in the browser, with no accounts and nothing stored.
A worked example, using figures taken from the guides read for this report and our own arithmetic: 100 g of filament at 35 per kg is 3.50. An 8-hour print at 150 W and 0.30 per kWh uses 1.2 kWh, which is 0.36. A 600 printer expected to last 3,000 hours costs 0.20 an hour, so 1.60 for 8 hours. The three together are 5.46. A 10% failure allowance adds 0.55, giving 6.01. Fifteen minutes of finishing at 20 an hour adds 5.00, so the cost is 11.01 before design time, shipping and fees.
ASSUMPTION: the tool is a planning estimate. The failure rate, printer lifetime and power draw are user guesses, and the result is only as good as they are.
Competitors and pricing
| Provider/substitute | Offer | Published price signal | What it already does well |
|---|---|---|---|
| PrintPal | Free web calculator | Free to use | Filament, electricity, machine wear and failure rate; shows typical printer wattage |
| Raspberry.tips | Free web calculator | Free to use | Adds a failed-print surcharge, a break-even mode and a selling-price mode |

| 3DWithUs | Free calculator and models | Not captured | Ranks near the top for the main phrase |
| Omni Calculator and Prusa’s calculator | Free calculators named in a roundup | Free to use | Omni splits material, labour and price; Prusa focuses on energy, labour and maintenance |
| BeYor add-on and a Chrome extension | Browser extensions | Not captured | Modes for home, friends and sale; printer price and lifetime; works offline |
| Spoolo | Phone app for makers and print farms | Free tier limited to one project; paid subscription for more | Costs, marketplace fees and filament stock in one app |

| General AI chat | Ask for a print cost | Already paid for or free | Can do the sum, but without a saved setup for your printer |
The opportunity and the gap
There is very little gap in the cost sum itself. The possible wedge is narrower:
- printer presets, so a new user picks a machine and gets a sensible wattage and lifetime instead of a blank field (PrintPal shows typical wattage ranges but not machine presets in the pages read);
- a clear selling-price step with marketplace fees, for the minority who sell, since the seller-shaped searches are almost empty;
- multi-colour and purge waste, which the pages read did not mention;
- a worked example on the page, with every figure shown, so a reader can follow the arithmetic.
None of these is a moat. Any of the sites above could add them in a day.
Monetisation (hypotheses, not built)
ASSUMPTION: advertisers pay for this traffic. The research shows an average cost per click of $2.64 for 3d print cost calculator and $1.90 for 3d print pricing calculator. That suggests ad or affiliate income is possible once there is traffic, for filament, printers or marketplace tools, but no traffic or revenue has been measured.
The site’s own rule is that monetisation must never change the calculator result. Because the searchers look like hobbyists, a paid product is unlikely: the free competitors above are the norm. No paid tier is planned, and no conversion rate, market size or revenue figure has been invented for this report.
MVP
To build
- One calculator page with the inputs above, a step-by-step cost breakdown and a selling-price step with an optional marketplace fee.
- A short set of printer presets, each with a stated source.
- A test suite with hand-computed expected values, including zero hours, zero failure rate, a very large print and empty fields.
- A page of copy in which every figure traces to a captured source or an executed test.
DON’T BUILD YET
- Accounts, saved printers or project history.
- Slicer file upload or G-code parsing.
- Filament stock tracking, order management or print-farm features.
- Separate pages for resin, each marketplace or each printer model. Their volumes are zero or tiny in the research.
Risks
- The first page is already full of free calculators with the same features, so a new page may not rank at all.
- The main phrase is seasonal (it peaks in July) and fell from 4,400 to 2,900 between August and September 2026.
- The keyword country was not recorded, so the volumes may not be UK-only or US-only.
- Searchers look like hobbyists, so money from them is likely to be advertising rather than sales.
- AI answers may absorb simple cost sums, as they have for other calculators.
- Defaults such as electricity price and printer wattage vary by country and machine, so wrong defaults would make the result look authoritative while being off.
- The host sites have their own indexing problems, so ranking may be slow regardless of quality.
Kill criteria and 30-day validation
Search traffic takes weeks, not days, so this test runs over 30 days once someone has built the tool. The thresholds below are proposals, not figures derived from data.
- Day 1: publish the tool. Submit its URL for indexing in Search Console.
- Days 2 to 14: confirm the page is indexed and note its first impressions.
- Days 15 to 30: track impressions, clicks and average position for 3d print cost calculator, 3d print pricing calculator and filament cost calculator.
Pass: indexed within 14 days; at least 500 impressions and 20 clicks across those terms in 30 days; an average position of 30 or better for at least one of them.
Kill: not indexed after 21 days despite a manual request, or fewer than 100 impressions in 30 days. If killed, leave the tool up and build nothing further around it.
Founder fit
Good fit for someone who can keep a small tool accurate and has a way to test the arithmetic against real prints. Poor fit for someone who wants to compete with print-farm software on features.
Final score
| Factor | Score | Reason |
|---|---|---|
| Pain | 10/20 | Underpricing prints is a real cost, but most searchers look like hobbyists with a small stake |
| Willingness to pay | 6/20 | Free calculators are the norm and the one paid app has a limited free tier |
| Competition gap | 3/15 | At least six free tools already cover the hidden costs |
| MVP feasibility | 14/15 | A browser calculator with simple arithmetic; not yet built |
| Recurring revenue | 2/10 | One-off use, no subscription logic |
| Acquisition | 7/10 | About 4,500 searches a month and rising, with low competition scores |
| SEO | 3/5 | Real volume, but a crowded first page |
| AI advantage | 1/5 | An AI chat can do the sum; the edge is presets and a shown method |
Total: 46/100. Research confidence: 55/100. Verdict: π‘ HOLD AS A BUSINESS, SHIP AS A FREE TOOL.

PRODUCT PRINCIPLE
One job: turn a print's filament, time, power and finishing work into a cost, then a selling price. It is a planning estimate. Say so on the page, and say what it leaves out (design time, shipping, tax).
INPUTS
Filament price per kilogram, grams used, print hours, printer average power in watts, electricity price per kilowatt-hour, printer price, printer expected lifetime hours, failure allowance in percent, minutes of hands-on finishing, hourly rate for your time, target margin in percent, optional marketplace fee in percent and fixed fee per sale.
RULES
1. Material = grams divided by 1000 times the price per kilogram.
2. Electricity = watts divided by 1000 times hours times the price per kilowatt-hour.
3. Machine wear = printer price divided by lifetime hours, times print hours.
4. Subtotal = material plus electricity plus wear. Failure allowance = subtotal times the percent over 100.
5. Labour = finishing minutes divided by 60 times the hourly rate.
6. Cost = subtotal plus failure allowance plus labour.
7. Selling price before fees = cost divided by (1 minus margin over 100). Reject a margin of 100 or more. With a marketplace fee, divide by (1 minus margin over 100 minus fee over 100) and add the fixed fee, and reject combinations that reach 100.
PRIVACY
Run entirely in the browser. No network calls, no storage, no analytics on field contents.
TESTS
Write test cases first and compute the expected values by hand from the rules, never from your own code. Check the worked example: 100 g at 35 per kg, 8 hours at 150 W and 0.30 per kWh, a 600 printer over 3,000 hours, 10% failure, 15 minutes at 20 an hour gives a cost of 11.01. Also cover zero hours, zero failure, a margin of 99, a margin plus fee at 100, empty fields, a negative value and an absurdly large weight.

Research date: 18 October 2026. Keyword volumes come from a KWS Everywhere bulk analysis run on that date; the country setting was not recorded, so treat the figures as indicative. Competitor information comes from two web searches on that date and the search-result summaries of those pages; pages were not opened in full and prices were not captured. Google positions were not checked. The worked example uses figures quoted in the guides above plus our own arithmetic. The 25-candidate screen used in earlier reports was not run for this idea. No conversion rate, market size or revenue forecast has been invented.
