The calculator collection

3D printing, resin, candle & fabric calculators

Turn a design into a material estimate or a cost breakdown. Match the calculator to the way the material is specified: filament by mass, resin by mixed volume, fabric by usable width, or lumber by board feet.

Restocking a candle order

Check ingredient stock and optional containers and wicks, then buy whole packs for the missing quantities.

Costing a filament print

Include slicer material use, print time, electricity, machine allowance, and hands-on labor. Estimated cost is separate from selling price.

Filling a rectangular mold

Calculate total mixed volume and use the product density for mass. The product’s mixing ratio remains a separate instruction.

Batching wax and fragrance

Enter the finished blend mass and choose fragrance percentage based on wax mass or finished blend mass, as specified by your tested recipe.

Cutting repeated fabric rectangles

Include seams on every edge and usable width. Check whether the fabric permits a different orientation.

Put the numbers to work

  1. Estimate production cost
  2. Compare margin and markup
  3. Calculate the sales needed to cover costs

Measured quantities are estimates before losses or process constraints. Always use the material supplier’s yield, density, mixing, and handling specifications.
