Best Things To 3D Print And Sell

Ranked by margin, with the material cost and print time that produce it.

As cited in

7 ranked · nothing here paid to be listed

  1. 1

    Custom jewelry

    The highest margin of any category at roughly 70 to 85 percent, and the lowest material cost per unit.

  2. 2

    Articulated fidget toys

    Around 65 to 80 percent. They print in place, need no assembly, and sell themselves in a video.

  3. 3

    Custom cookie and clay cutters

    The lowest barrier of the lot: pennies of filament, minutes to print, and cheap to sell as a set. Where most people should start.

  4. 4

    Tabletop gaming miniatures

    Roughly 60 to 75 percent, and a customer base that buys repeatedly rather than once.

  5. 5

    Home decor

    Around 60 to 75 percent. Vase-mode pieces cost almost nothing and photograph well.

  6. 6

    Cosplay props

    Roughly 55 to 70 percent. Slow to print, and priced accordingly.

  7. 7

    OEM replacement parts

    No retail substitute, which is exactly what lets you set the price.
