Prof. Lab PETG Transparent Blue 1 kg – strong and translucent PETG filament

Prof. Lab PETG Trans. Blue is a versatile PETG filament in transparent blue color, designed for users who require a combination of high mechanical resistance, reasonable temperature resistance and an attractive translucent appearance.

Thanks to the typical properties of PETG, it is suitable for both functional prototypes and technical parts, as well as for aesthetic models, illuminated elements and electronics covers. The transparent blue color lets light through, making the filament ideal for LED projects, decorations and transparent containers.

Main advantages of PETG Prof. Lab Transparent Blue

• Transparent blue color – a beautiful translucent shade, ideal for lighting and design applications.
• High toughness and durability – PETG is stronger and more durable than PLA, less brittle and suitable for functional parts.
• Good temperature resistance – compared to PLA, it tolerates higher ambient temperatures better (typically around 70–80 °C for PETG materials).
• Minimal shrinkage and deformation – lower tendency to warp than ABS, suitable even for open printers.
• Excellent layer adhesion – ensures strong, homogeneous prints.
• Easy printing – without significant odor, suitable even for users transitioning from PLA to a more durable material.

Recommended use

Prof. Lab PETG Transparent Blue is great for:

• functional prototypes and technical parts, holders, grips, covers
• transparent and semi-transparent containers, bins, packaging
• LED illuminated objects, lamps, signal elements
• protective electronics covers, transparent lids
• decorations, models, cosplay accessories, where you want a translucent blue effect

When printing transparent parts, it is advisable to choose a larger layer height and fewer perimeters, or slower printing, so that the print is as optically clear as possible.

Recommended printing parameters

Typical parameters for PETG filaments 1.75 mm / 1 kg:

• Filament diameter: 1.75 mm
• Nozzle temperature: approx. 230–250 °C (depending on the printer and desired appearance)
• Bed temperature: approx. 70–85 °C
• Print speed: approximately 40–80 mm/s
• Cooling: low to medium (for transparent parts, rather lower for better layer bonding)

Specific values may vary depending on the printer used, hotend, cooling and model geometry – we recommend printing a smaller test object and fine-tuning the parameters.

Material properties of PETG (general)

• Material: PETG (polyethylene terephthalate glycol)
• Character: tough, durable, with excellent layer adhesion
• Chemical resistance: good resistance to many common chemicals
• Moisture resistance: lower absorption than e.g. nylon, yet it is advisable to store the filament in a dry place

The filament is wound on a spool with a net weight of 1 kg, vacuum packed with desiccant for the best possible shelf life.

Tips for storage and printing

• Store in a dry place – ideally in a sealable box with desiccant.
• If the filament has been left open for a long time, dry it (e.g. approx. 60–65 °C for several hours) to eliminate popping and bubbles.
• For better adhesion to the bed, use a PEI surface, glue stick, special adhesive or textured bed.
• For taller models with small contact to the bed, consider using a brim or raft.

Summary

Prof. Lab PETG Trans. Blue (transparent blue) is a reliable and versatile PETG filament in an attractive translucent blue shade. It offers a combination of strength, toughness and easy printing, making it suitable for both technical parts and design and lighting projects.
