New in 3.3

Printer care, print costs and more printers

Version 3.3 looks after your printers, shows what every print really cost and connects to more printers on your home network.

The Printer Care screen in 3DCDesign: printer hours, one open task, and lubrication, nozzle and general service schedules, each with a Done button.

Printer Care

Maintenance that keeps count

Printer Care tracks each printer's maintenance by hours, days, prints or kilograms of filament. Tap Done when you service it, start from a ready-made task set, and get a reminder when a task comes due.

  • Due by hours, days, prints or filament used
  • Ready-made task sets and an hour meter
  • Reminders when a task comes due
The Stats screen in 3DCDesign: a month's print total split into material and power, the most expensive prints and why prints failed.

Print cost and stats

What did that print really cost?

Every finished print shows what it spent on filament and electricity. Stats show prints and filament by week, month or year, this month's spend, why prints failed and your records.

  • Filament and power cost on every finished print
  • This month's spend and your most expensive prints
  • Why prints failed, printer by printer

FAQ

Questions, answered

Is 3DCDesign free?

Yes. The download is free, and so is everything for running your workshop: printers and Printer Care, spools, prints and what they cost, the print price calculator, quotes, receipts and backups. Business Premium is an optional subscription for sellers who need to issue invoices and other business paperwork.

Do I need an account?

No. There is no sign-up and no login. The app keeps your profile on your device, and that is all.

Where is my data?

On your phone or tablet. Your records stay on this device unless you export, share or save a backup file. Apple or Google may include app data in your device backup, depending on your settings.

Which printers connect?

Moonraker/Klipper, OctoPrint and PrusaLink hosts, Bambu Lab printers (status only), and the Elegoo Centauri Carbon, Creality K2 and Snapmaker U1, on your own network. Connections are optional and off until you set them up, and every command asks you to confirm it first. Every other printer works with manual logging.

What does Business Premium add?

Issuing and correcting invoices, purchase orders, Customer Pro tools, Market Day, Etsy and Shopify order import, an accountant export, saved what-if scenarios and more than 25 active customers. Without it, everything you already made stays yours: you can still open it, edit drafts, prints, spools and customers, record payments, export, back up and restore.
