3D Filkemp PETG – filament for 3D printing

3DFilkemp PETG Blend is a PETG-based filament (PETG blend) for 3D printing, aimed at users looking for a balanced behavior between easy setup, good appearance, and practical mechanical properties for functional details. It is suitable for everyday engineering applications, prototyping, and manufacturing parts where better durability and stability compared to base materials for hobby printing are expected.

Key advantages (confirmed data)

• Recommended nozzle temperature: ± 235–250°C.
• Recommended heated platform temperature: ± 20–60°C.
• Recommended cooling (fan): 0%–50%.
• Diameters: 1.75 mm
• Net weight of spool: 1 kg.

What is PETG Blend and who is it suitable for

PETG (glycol-modified PET) is a widely used material for 3D printing when a combination of better durability and lower tendency to deform is sought compared to more finicky engineering plastics. The "blend" variant usually means that the material is formulated with additives/modifiers for targeted printing behavior or for visual/mechanical qualities. For the specific product 3DFilkemp PETG Blend, the available public data mainly describe recommended settings and diameter/color options; detailed mechanical properties (strength, impact resistance, density, diameter tolerance) have not been confirmed by sources in the available documentation at this time.

Suitable for:

• users who want a predictable workflow and stable settings;
• functional prototypes and enclosures;
• mounting elements, holders, clamps, and general engineering details;
• parts where appearance (smooth/glossy surface with PETG) is important, without switching to specialized composite filaments.

3D printing settings and how they affect the result

For PETG, the most sensitive parameters are the nozzle temperature, cooling, and platform temperature. The manufacturer provides the following guidelines for 3DFilkemp PETG Blend:

• Nozzle temperature: ± 235–250°C
• Cooling (fan): 0%–50%
• Heated platform: ± 20–60°C

Practical guidelines (best practices, without claims for specific numerical results):

• Layers and adhesion: If you are looking for maximum interlayer adhesion, start with lower cooling and stabilize the nozzle temperature within the recommended range. Increasing cooling may improve detail in overhangs, but sometimes increases the risk of weaker interlayer bonding.
• “Stringing” and fine threads: PETG can form strings at inappropriate temperature or retraction. The approach is: calibrating retraction, controlling temperature, and reasonable cooling (within the recommended range), instead of aggressively “forcing” the cooling.
• Adhesion to the platform: PETG often has strong adhesion to some surfaces. Use an appropriate release strategy (e.g., compatible adhesive or intermediate layer according to the platform) to avoid difficulty in detaching the part.

Workflow: from the spool to the finished part

PETG Blend is compatible with the mainstream approach in FFF/FDM 3D printing: loading the filament, setting up a profile in the slicer, and executing a test geometry for fine-tuning. The available product data confirms a diameter of 1.75 mm, which means it is important to choose the right option for your extruder.

Recommended sequence:

1. Check if your printer is for 1.75 mm filament.
2. Load the material and perform a short test for stable flow.
3. Start with temperatures of ± 235–250°C (nozzle) and ± 20–60°C (platform), then adjust according to geometry and surface.
4. Set the cooling between 0% and 50% according to the need for detail/overhangs.
5. Finalize the profile with short retraction and overhang tests (especially for complex models).

Compatibility and ecosystem

the product is available in 1.75 mm diameter and on a 1 kg spool. This makes it applicable for a wide range of 3D printers, as long as the extruder matches the chosen diameter.

specific recommended slicers, profiles, supported formats, diameter tolerance, drying (temperature/time), as well as specific bed surfaces.

Spool design and practicality for daily work

The filament is on a spool with net weight 1 kg. When choosing a color, it is good to consider the visual requirements of the project and post-processing. According to available information, the product is offered in several colors, including Snow White, and Graphite Black (the options may depend on availability).

Professional scenarios where PETG Blend makes sense

• Functional prototypes: more predictable behavior over a series of iterations without constant material/profile changes.
• Casings and covers: a good base for parts where a stable appearance and practical use are sought.
• Holders and mounting elements: suitable for parts that need to maintain shape under normal use.
• Work fixtures (jigs) and templates: a convenient choice for auxiliary tools in a workshop/laboratory.
• Short runs: when you want a repeatable process with clear recommended adjustment ranges.

Limitations and best practices

• Moisture control: PETG can be sensitive to humidity (symptoms: "cracking", roughness, unstable flow). Store the spool in a dry environment and use a box/container if needed. Availability data: not confirmed by sources for a specific drying regime for this product.
• Excessive adhesion: on some beds, PETG may "bite". Use an appropriate release agent according to the surface to avoid damage.
• Fine strings (stringing): the solution is usually a combination of the right temperature, retraction, and moderate cooling, not an extremely low temperature.
