How to Cut Poop Waste by 60%
- Flush into Objects' Infill: In BambuStudio, check "Flush into this object's infill" to turn purge into hidden internal support.
- Lower Flushing Multiplier: Reduce default 1.0 to 0.6–0.7 for similar colors (e.g. Red to Orange). Saves up to 40% filament.
- Print in Multiples: Printing 4 dragons on the same plate shares the exact same filament purge per layer!
Direct Slicer Parsing
No manual typing required. Drop your exported BambuStudio or OrcaSlicer `.3mf` and all filament weights, flush purge, and print times load instantly.
True AMS Poop Accounting
Multi-color prints can waste up to 60% of filament spools in nozzle flushes. See the exact dollar cost of your purge waste before starting the print.
Etsy & Commercial Markup
Factor in machine depreciation, electricity kilowatts, labor, and Etsy's transaction fees to ensure every batch yields healthy profits.
The Professional 3D Print Production Cost Formula
Most hobbyists make the mistake of only calculating filament weight. Commercial print farms and top Etsy sellers use this comprehensive formula:
Frequently Asked Questions
Everything you need to know about Bambu Lab print costing and file parsing.
What is Bambu Lab 'Poop' and why does it cost so much money?
When a multi-color 3D printer like the Bambu Lab X1C, P1S, or A1 switches between filament spools using the AMS (Automatic Material System), it must purge the previous color out of the hotend nozzle. This purged plastic curls and drops out of the back chute into what the community calls the 'poop chute'. On intricate multi-color prints with hundreds of layer switches, this purge waste can often exceed the actual weight of the printed object, significantly increasing your filament costs.
Does this tool upload my proprietary .3MF or .GCODE files to any server?
No! All file parsing is done 100% inside your web browser using client-side JavaScript (JSZip and DOMParser). Your proprietary CAD models, 3MF archives, and G-code files never touch our servers or leave your local machine.
How does the tool calculate multi-color AMS filament usage?
BambuStudio and OrcaSlicer store detailed XML slicing telemetry inside the .3MF package under 'Metadata/slice_info.xml'. Our parser extracts the exact grams used for the model, the grams flushed down the purge chute per spool slot, and the total print time in seconds down to the millisecond.
How should I price 3D printed items for Etsy or local clients?
A sustainable maker pricing formula must include: (Filament Cost + AMS Waste Cost + Electricity + Machine Wear & Tear + Packaging) / (1 - (Target Profit Margin + Platform Fees)). Our calculator does this automatically so you never undercharge or sell at a hidden loss.
