Filamentree PETG Luminous Red 1kg

Filamentree PETG Luminous Red is a premium PETG filament with a luminescent (glowing) red color, suitable for demanding users and hobby enthusiasts. It combines the mechanical resistance of PETG, good chemical and thermal stability with an attractive luminous effect, which makes printed objects glow in the dark.

Thanks to low deformation and good adhesion to the bed, it is ideal for dimensionally accurate and functional parts, but also for decorations, cosplay accessories, models, and elements for lighting.

Main advantages and use

Luminescent red color – the filament accumulates light and glows in the dark, great for decorations, logos, inscriptions, or safety markings.
High strength and toughness – PETG is more durable than PLA and tolerates mechanical stress better.
Low shrinkage and warping – suitable for larger models and functional components.
Good layer adhesion – strong, cohesive prints without significant weak spots in the direction of the layers.
Higher thermal resistance than PLA – parts deform less at increased operating temperatures.
Easy printing on most FDM printers – an enclosed chamber is not necessary, a heated bed and correct settings are enough.

Typical use:

design and decorative models with a glowing effect
covers, holders, and functional components
elements for lighting, signals, marking
cosplay, promotional, and advertising items

Recommended printing parameters

Specific values may vary depending on the printer, nozzle, and environmental conditions, recommended range for PETG Filamentree:

Parameter	Recommended value*
Nozzle temperature	230–250 °C
Bed temperature	70–80 °C
Printing speed	40–60 mm/s
Part cooling	20–60 % (depending on geometry)
Recommended bed type	glass, PEI, textured sheet, adhesive spray / glue

*Start at the middle value and adjust according to the specific printer and print result.

To minimize stringing with PETG, it is recommended to:

slightly reduce the nozzle temperature if the surface is too "stringy"
increase retraction compared to PLA
reduce travel speed during extremely long travel movements

Material properties

Material: PETG (polyethylene terephthalate glycol)
Filament diameter: 1,75 mm (high dimensional accuracy)
Filament spool weight: 1 kg of net material
Color: Luminous Red
Printing type: FDM/FFF 3D printing

PETG is a low-shrinkage and dimensionally stable material from production, suitable for combining functionality and aesthetic appearance. The luminescent pigment in the color does not fundamentally affect printing behavior, but for very fine details, a slight reduction in speed may be appropriate to achieve maximum surface quality.

Storage and handling

To ensure the filament retains its properties and glowing effect, we recommend:

storing the spool in a closed bag with a desiccant (silica gel)
protecting from moisture and direct sunlight
in case of dampness, dry the filament before printing (e.g., in a filament dryer or in an oven with precise temperature regulation according to the manufacturer's recommendations)

Proper storage helps minimize stringing, bubbles in the print, and improves layer adhesion.

Who is Filamentree PETG Luminous Red suitable for

For beginners who want to move from PLA printing to a more durable material and at the same time have an attractive glowing effect.
For advanced users and small businesses looking for reliable PETG for functional parts, covers, and components.
For designers, model makers, and the cosplay community who need visually striking prints with a special effect.

Filamentree PETG Luminous Red 1kg is a great choice if you are looking for a combination of strength, reliable printing, and a distinctive luminescent appearance in one spool of filament.
