My Print Farm

Your fleet, with honest estimates

Choose real printer models from the reviewed GoodPrints3D catalog. Set quantities, give groups a nickname and keep private notes. Import owned catalog printers from My Print Bench when useful. Your Bench collection is preserved.

What the numbers mean

Build capacity sums the published build envelopes of the printers with reviewed dimensions. It is not a single printable space. Advertised speed is a manufacturer maximum, not a measured production rate. Resin and SLS printers can join the shelf; the extrusion challenges use active filament printers only.

Each filament printer uses your personal flow value, a reviewed published flow value when available, or the shared assumed flow. The first catalog snapshot has no published volumetric flow values. The default 8 mm³/s is an editable planning assumption, not a specification for your machine. Exclude printers without a published or personal flow value if you prefer.

The extrusion cross-section is h × (w − h) + πh² / 4, using your layer height h and line width w. Per-printer flow is the smaller of the selected flow and advertised speed multiplied by this area, where speed is known. Quantities are summed and multiplied by the selected utilization, the fraction of clock time actively extruding. Travel, failures, warmup, maintenance and assembly are not separately modeled. Use a slicer for a real job estimate.

The Eiffel Tower challenge

The official Eiffel Tower figures give 7,300 tonnes for the metal structure. Dividing by an assumed iron density of 7.85 t/m³ gives about 930 m³. The challenge asks how long it would take to extrude that volume of plastic, with all included printers in parallel. It does not describe a sliced tower model, a scale replica, construction time or a structurally viable plastic tower.

The spool challenge uses your selected plastic density. The default 1.24 g/cm³ comes from the Prusament PLA technical data sheet and is an editable PLA example. The 1,000-part challenge uses an example volume per part, not a measured model. Prusa’s volumetric speed guide explains why material, nozzle and hotend affect achievable flow.

Keep your farm

Guest saves stay on this device. Sign in with your GoodPrints3D forum account to sync the fleet, quantities, notes and assumptions privately across devices. Farm backups are separate from Labs workspace backups. Import merges new record IDs and preserves existing records. The demo changes nothing in your saved farm until you choose Keep this farm. No printer connection or AI tokens are required.
