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.

Pro tip: maximizing the metallic effect

Slow down Slower speeds let pigments align for a smoother, more reflective shimmer
Thin layers 0.15mm produces the finest, most uniform metallic finish
Full cooling 100% fan locks pigments in place, preserving reflective quality

Orientation and lighting

Get the most out of your metallic prints

Print orientation

Vertical wallsStrongest shimmer — layer lines catch light at multiple angles
Top surfacesMore matte — filament laid flat without light-catching ridges
OverhangsCan look duller — use supports beyond 45°

Lighting for display

Side / angled LEDMaximum metallic pop — best for shelf display
Natural sunlightTrue color depth — best for photography
Diffused / ambientSubtle sheen — understated elegance
Orient figurines and display pieces so the most visible surfaces are vertical walls, not top faces. This maximizes the metallic shimmer where people actually look.

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

Storage: Sealed with desiccant, below 20% RH. Dry at 50°C for 4–6 hours if exposed. Wet filament = popping, rough texture, killed shimmer.

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.
