3D printer filament c-tech Premium Line PLA Blue Violet RAL4005 1.75 mm 1 kg

c-tech Premium Line PLA filament in Blue Violet (RAL4005) is a 1.75 mm, 1 kg spool formulated for FDM/FFF 3D printers. Manufactured from polylactic acid (PLA), this filament is intended for users who need reliable dimensional stability and consistent color reproduction matching the RAL4005 tone. The material prints at standard hotend temperatures, produces low odor during extrusion, and delivers smooth surface detail suitable for prototypes, display models and hobby parts.

Advantages

The filament provides predictable feeding and reduced warping due to PLA’s low thermal shrinkage. Its 1.75 mm diameter tolerance supports stable extrusion and consistent layer adhesion for fine detail. The Blue Violet (RAL4005) color is produced to give uniform coloration across prints, aiding in projects that require accurate color matching. The 1 kg spool format balances build volume and storage convenience for home and small workshop use.

Suitable for

• Prototype parts and functional mock-ups
• Visual models and display pieces requiring RAL4005 color
• Hobbyist prints, figurines and decorative items
• Educational projects and classroom 3D printing
• Small batch production where PLA mechanical properties are sufficient

Key specifications

• Material: PLA (polylactic acid)
• Color: Blue Violet (RAL4005)
• Diameter: 1.75 mm
• Net spool weight: 1 kg
• Typical print temperature range: standard PLA hotend temperatures (approx. 190–220°C)
• Bed adhesion: glass, blue tape or light adhesive; heated bed optional
• Recommended print speed: moderate speeds for best surface finish

How to use

Load the 1.75 mm filament into an FDM/FFF printer following the printer manufacturer’s filament loading procedure. Set the hotend temperature to a typical PLA range (around 190–220°C) and adjust bed temperature or adhesion method according to your printer and part geometry. Calibrate extrusion multiplier and print speed on a small test object to confirm dimensional accuracy and color consistency. Monitor the first layers to ensure good bed adhesion and fine-tune retraction settings to minimise stringing.

Usage recommendations

Store the filament spool in a dry environment or sealed bag with desiccant to preserve print quality. For best color fidelity to RAL4005, maintain consistent printer settings and avoid excessive overheating which can alter hue and surface appearance. Use cooling fan after the first few layers to improve overhangs and surface detail when printing small or detailed parts.
