Every time I switch filament brands, the same ritual: Google "Bambu Lab PLA Basic temperature", scroll through Reddit threads, find a comment from 2023, try 220°C, get stringing, try 230°C, get blobbing, end up at 225°C after burning half a spool.

This is insane. Every filament has an optimal temperature range. The manufacturer prints it on the box. But somehow we're all still guessing.

So I built FilamentDB — an open-source database of real filament parameters that you query from your terminal.

What It Does

# Search for a filament filamentdb search "PLA+"

# Get exact recommended settings filamentdb recommend --brand "Bambu Lab" --model "PLA Basic"

# Compare two filaments side by side filamentdb compare "Bambu Lab PLA Basic" "eSun PLA+"

# Find alternatives when your go-to is out of stock filamentdb alternatives PETG --exclude eSun
