Ultimate 3D printing guide for Metallic PLA
Overview
What makes PLA Metallic different
Metal surface texture
Metallic pigments create a rich, reflective finish that catches light at every angle
No metal particles
Uses pigment, not metal infill — your brass nozzle stays safe with zero wear
Premium finish
Straight off the build plate — no sanding, priming, or painting required
Numakers PLA Metallic delivers a rich, reflective metal-like finish using specially engineered metallic pigments — not metal particle infill. Print with the ease of standard PLA on any FDM printer using a standard brass nozzle. The metal surface texture and metallic shine reveal themselves under natural and angled lighting. Fully AMS compatible. Built for display pieces, figurines, cosplay props, home décor, and prints that demand a premium finish. Available in 6 curated metallic tones.

Troubleshooting
Common issues and how to fix them
Dull, non-reflective surface
CauseTemperature too low or speed too high
FixIncrease nozzle temp by 5°C, reduce speed
Stringing between parts
CauseTemperature too high or retraction too low
FixDrop temp by 5°C, increase retraction, enable wipe
Inconsistent extrusion
CauseFilament absorbed moisture
FixDry at 50°C for 4–6 hours, do a cold pull
Layer separation
CauseTemperature too low, layers not bonding
FixIncrease nozzle temp by 5–10°C, reduce fan to 80%
Warping on corners
CauseBed temp too low or poor adhesion
FixBed to 60°C, add 5–8mm brim, block drafts
Blobs or zits
CauseRetraction or coasting not tuned
FixEnable coasting (0.03–0.06mm³), tune retraction speed
FAQ
Common questions answered
Do I need a hardened steel nozzle?
No. PLA Metallic uses metallic pigments, not metal particles or abrasive fillers. Standard brass nozzle works perfectly with zero measurable wear.
Does it contain real metal?
No. The metal surface texture and shine come from specially engineered metallic pigments. This is what makes it easy to print — it behaves like standard PLA.
Is it AMS compatible?
Yes. Compatible with all AMS series. Feeds and retracts normally, no special settings needed.
Can I paint PLA Metallic prints?
You can, but you'd lose the metallic effect. The whole point is to skip painting. Use standard PLA if you plan to paint.
Is it food safe?
No. Like most specialty filaments, PLA Metallic is not certified for food contact.
