📦 Inventory
The Inventory module lets you keep track of your stock of finished pieces and of the workshop's materials and consumables: filament, resin, supplies and your own manufacturers.
The header figures
| Indicator | What it shows |
|---|---|
| Filament for orders | Grams of filament required by active orders (In production or Created), broken down by color. |
| Resin for orders | Resin required by active orders. |
These indicators help you know whether you have enough material for the orders in progress before the printer grinds to a halt.
Material catalog
Clicking "Catalog" takes you to the global library of filaments and resins that BolloPrint maintains for every workshop.
You can filter the materials in several ways, so you can see what's available by color, manufacturer, etc.
Click a material's row to open its datasheet, with the summary of its characteristics and all the specifications.
The catalog is read-only: BolloPrint maintains it and it's the same for every workshop. You don't create new filaments or resins there — what you do is bring them into your inventory (see below). If you work with a brand that isn't listed, you add it from the Manufacturers tab.
The five inventory tabs
This is where you record what you have. It's classified into five tabs:
| Tab | What it contains | Main button |
|---|---|---|
| Stock | Pieces you've already made, ready to ship. | Add pieces |
| Filament | Stock of filament spools (PLA, PETG, ABS, TPU…). | Add from catalog |
| Resin | Stock of resins for SLA/MSLA printing. | Add from catalog |
| Supplies | Other consumables and spare parts: isopropanol, sandpaper, spray, packaging, nozzles, belts… | New supply |
| Manufacturers | Your own brands/suppliers, on top of the ones that already come in the global catalog. | New manufacturer |
Notice that the button changes depending on the tab:
- Filament and Resin come from the global catalog → "Add from catalog". Select the materials you want (you can pick several at once) and click "Add". Once the material is in the list, click it to open a panel where you update the units and the cost.
- Supplies and Manufacturers are yours, they don't come from any catalog → you create them directly with their own form.
- Stock is filled in by picking pieces from your design catalog.
💡 Good practice
Remember to update it when you use up materials too, if you want the header figures to warn you before you run out halfway through an order.
The "Cost per Kg" and why it matters
The Filament and Resin tabs have a Cost per Kg column. You don't type it in: it comes from two figures you do enter.
You record what the spool (or the bottle) cost you, which is what you actually pay. The catalog record knows how much material it holds when full. From those two things the price per kilo is worked out:
what you paid ÷ what a full spool holds = cost per kilo
If you have several units of the same material bought at different prices, the average of those with a cost entered is used. The ones at zero don't count — they don't drag the average down, they simply don't take part.
This number isn't there for decoration: it's the one the piece takes into its cost. When you pick a material from your inventory on a piece, its Cost per Kg becomes that piece's Cost/kg. That's why it pays to keep the costs up to date: it's the difference between a sale price you can defend and one you made up.
Watch out for the numbers in grey
When a figure is missing, the column shows you a grey estimate rather than leaving you in the dark: if the material has no weight on its record, it works out the price per kilo assuming a 1 kg spool; and if it has no cost either, it shows you your workshop's default value.
The grey default value really is what gets charged: a material with no cost is costed with your workshop's rate for its type, exactly as if you had picked the color by hand. As soon as you give it a cost, it turns black and yours takes over.
In black = a real figure of yours. In grey = you're still using the workshop default.
Every material in the catalog already has its weight. If you ever see one without it, the grey figure comes from assuming a 1 kg spool — an assumption of ours, not the one used for costing — and it means that newly added record is missing the data: let us know and we'll fill it in.
Who can manage the inventory?
Workers, Admins and Owners can view and update the inventory. Read-only users can only consult it.
