Product description
Prusament PETG Ultramarine Blue Transparent 1kg
Prusament PETG Ultramarine Blue Transparent is a premium PETG filament manufactured in‑house by Prusa Research. Each spool is carefully inspected during production and Prusa guarantees a filament diameter of 1,75 mm with a tolerance of ±0,02 mm, ensuring stable flow, reliable printing, and minimal differences between individual batches.
The semi-transparent ultramarine blue color gives prints an elegant, saturated, and at the same time “deep” appearance – an excellent choice for designer models, functional parts visible at first glance, and illuminated elements.
PETG material properties
PETG is among the most popular materials for FDM/FFF 3D printing. It combines easy printing similar to PLA with much better mechanical and heat resistance.
Main advantages of PETG:
- excellent layer adhesion – suitable for watertight and high‑strength parts
- higher heat resistance than PLA – suitable for indoor and outdoor use
- low shrinkage and minimal warping when printing even larger objects
- toughness and flexibility – parts are not as brittle as from PLA
- suitable for functional components, mounts, covers, jigs, parts for workshop and household
The semi‑transparent Ultramarine Blue variant additionally allows for a striking translucent effect, especially when printing thinner walls or in combination with backlighting.
Key advantages of Prusament PETG Ultramarine Blue
- Premium filament from Prusa Research – consistent quality, in‑house production
- Diameter 1,75 mm with accuracy ±0,02 mm – stable extrusion and lower risk of nozzle clogging
- Semi-transparent ultramarine blue – attractive, saturated blue coloring with a depth effect
- Excellent layer adhesion – suitable for demanding and mechanically stressed parts
- Low warping – easy printing of larger objects even without an enclosed chamber
- Good resistance to higher temperatures (typically around 70–80 °C for finished prints)
- Ideal for functional, technical, and designer models
- Verified and ready‑to‑use profile settings in PrusaSlicer
Recommended applications
Prusament PETG Ultramarine Blue Transparent is especially suitable for:
- mounts, holders, brackets, jigs
- electronics enclosures, boxes, mounting frames
- parts for household and workshop (organizers, hooks, tool holders)
- outdoor components exposed to sun and weather (with reasonable protection)
- aesthetic and designer models requiring a semi‑transparent blue effect
- 3D printer parts and accessories where higher strength and toughness are needed
Printing settings (guideline)
According to Prusa Research recommendations for Prusament PETG:
- Nozzle temperature: approx. 250 °C ± 10 °C
- Bed temperature: approx. 80 °C ± 10 °C
- Recommended bed surface: textured or satin steel sheet, or PEI
For beginners, ready‑made profiles for Prusament PETG are available in PrusaSlicer, so you only need to select the appropriate material and printer – retraction, temperature, and speed parameters are pre‑configured.
Tips for printing PETG
- PETG tends to bubble more and create stringing – well‑dried filament and properly tuned retraction help.
- Before printing, clean the bed surface with isopropyl alcohol; on smooth PEI, a separation layer (e.g. glue stick) may be useful so that parts do not stick too strongly.
- After printing, fine strings can be removed with a heat gun by briefly and carefully heating the surface.
