Production workflow for 3D print farms.

Know every spool you own, every print you've run, and what each one actually cost. Built to run an eight-printer farm — now opening up to other farms.

Mobile-first · Spoolman-compatible · no credit card

Shelf of QR-labelled filament boxes — every label matches a spool in the system
Know what you have without walking the rack.

Filament inventory grid — 124 types and 277 spools with per-type stock, urgency and location

Already built · product as of August 2026

This isn't a mockup. The core loop is running today.

Six screens from the real admin app, in production-loop order — the same tool that runs a working farm right now.

01

Filament inventory

Every spool tracked — status, weight and location down to the shelf. The grid is the rack, without the walk.

Invoice import review — parsed supplier PDF lines matched to catalog filaments before import
02

Supplier invoice import

Drop the supplier PDF, review the parsed rows, done. Ordered spools reconcile to on-hand stock the moment the box arrives.

Printers list — eight machines across two brands with loaded-slot counts and live drying badges
03

Printers & AMS

Slots know what’s loaded, so spool location is derived — not hand-maintained. AMS, feeders and dryers modeled as they really are.

Model catalog — commercial-licensed models with variants ingested from five different sources
04

Model catalog

Models → variants → parts, the source of every print — with the license on every model, so “am I allowed to sell this one?” is never a guess. Reprint a proven variant without rebuilding the setup from scratch.

Print log entry showing its full cost arithmetic — per-slot filament grams, electricity, depreciation and labor
05Differentiator

Print log + costs

Log a print → filament auto-deducts from the loaded spools → true cost captured per print. The loop closes itself.

Drying overview — active drying cycles across the farm with per-cohort progress
06

Drying

Every spool knows when it was last dried, and every cycle running across the farm sits on one page.

What's next · on the road to beta

Intelligence on top of the loop that already runs.

“What can I print now?”

Match open orders and models against actual stock — no guessing which jobs are unblocked.

Short-stock & blocked view

See what’s about to stall production before it does, with the spools that would clear it.

Per-print margin

Profitability layered on the cost data the loop already captures — margin per print, per model.

And a real API — Spoolman-compatible import, bulk export, and integrations (Shopify, Square, Bambu Cloud) — on the road to beta.

The gap we're closing

Existing tools are inventory trackers or DIY databases. Farms need both — plus a workflow.

Inventory trackers are great for hobbyists but blind to the production workflow that actually runs a farm. Spoolman has a real API but a DIY interface you self-host. Polished UIs ship without an API or team support. Print farms fall straight through that gap.
