Our Mission

3D Costify was built for one simple reason: accurate 3D printing cost calculation was unnecessarily complicated. Free calculators ignored marketplace fees, printer depreciation, and the risk of failed prints. Paid tools were too expensive for hobbyists and small businesses.

Our goal is to provide the most accurate and intuitive cost calculation tools for everyone — from the home hobbyist to the Etsy seller to the professional print farm running production volumes.

What Makes 3D Costify Different?

  • STL & G-code Parser: Model parameters are analyzed securely in your browser using Three.js — your data never leaves your device.
  • Marketplace Fee Optimization: A reverse mathematical formula precisely accounts for Etsy, Shopify, and other platform fees so you always protect your desired profit margin.
  • Print Cost Showdown: Compare two parameter configurations side-by-side to find the most cost-effective setup.
  • Printer Depreciation: The calculator accounts for equipment wear distributed over print hours, just like professional print services do.
  • Failure Risk Buffer: Automatically add a percentage risk buffer to cover the statistical cost of failed prints.

Who Is 3D Costify For?

  • Hobbyists & Makers: Calculate the true cost of every print before deciding on a price for friends or customers.
  • Etsy & Shopify Sellers: Set prices that cover platform fees and leave you with real profit after every sale.
  • Print Farms: Manage costs and margins across multiple projects simultaneously at production scale.
  • B2B Service Providers: Generate client quotes that include labor time, depreciation, and profit markup.

Tomasz Lichosik

Software Engineer Poland, EU

Tomasz is a full-stack software engineer with a background in supply chain systems and logistics. He built 3D Costify to solve a real problem he encountered: the absence of a good, free 3D printing cost calculator that properly accounts for marketplace platform fees and operates without uploading files to external servers. All calculation logic runs entirely client-side, built on rigorous research into real-world print shop economics.

Technology & Transparency

3D Costify is built on open-source technologies. 3D model parsing uses Three.js for STL analysis. The application is powered by Node.js and Express. No proprietary black-box components are used.

We do not sell your data, we do not monetize your inputs, and we do not require any account to use the calculator. The site is funded by non-intrusive display advertising (Google AdSense), fully subject to your cookie consent preferences.

Frequently Asked Questions

Is 3D Costify completely free to use?

Yes, completely. There is no registration, no subscription, and no usage limits. All features — including the cost calculator, G-code parser, and comparison tool — are free for both personal and commercial use.

Is my data safe?

Yes. All calculations and STL/G-code file analysis happen exclusively in your browser. No data is transmitted to our servers. The website is funded by non-intrusive Google AdSense advertising.

How does the calculator account for Etsy or Shopify fees?

The calculator uses a reverse mathematical formula: you enter your target net profit, and the tool automatically calculates the listing price that, after deducting all fees (listing, transaction, payment processing), will leave you with exactly that amount.

Can I use the generated prices for commercial purposes?

Absolutely. 3D Costify is designed specifically for commercial use — for sellers on Etsy, Shopify, Amazon Handmade, local markets, or direct B2B clients. The pricing formulas reflect real industry economics.
