🛠️ Let VARVX configure it for me – choose the best orientation and strength Answer 4 quick Yes/No questions below, pick the usage class & material, and describe the part.

💪 Must the part withstand force / load?

✨ Must the exterior be ultra-detailed? ?We print with a very fine layer height (0.12 mm instead of standard 0.20 mm). This brings out fine details and smoother shallow curves, but significantly increases print time (and price) and can slightly reduce mechanical strength. 💡 Tip: On standard straight and functional parts the difference is barely visible to the naked eye – standard layers are usually best (choose No).

🪄 Must supported surfaces look as clean as the rest of the part? ?When part of the model overhangs in the air (angle > 45°, red areas in 3D view), temporary supports must be printed underneath. Choosing "No" (standard supports): a tiny air gap (~0.2–0.3 mm depending on nozzle) is left so supports can break away, leaving the supported surface slightly rougher with ~0.2–0.3 mm dimensional variance. Choosing "Yes" (dedicated support interface): we print the contact layer with a 2-nozzle printer using a separate release material at 0 mm gap, keeping the supported surface smooth, strong and accurate (slower & higher cost). 💡 Tip: If the supported side is hidden and ~0.3 mm variance does not matter, choose No – it is much more affordable.

☀️ Will it be used outdoors, in a car or warm area?

🧪 Choose usage class and filament: Click a usage class and select a filament below – see heat resistance and best use cases, and the price updates instantly.

Describe what the part does and how it is loaded:

Where and in what direction do forces, bending or tension act? (e.g. "bolt pulls from this hole", "clip bends outward" – we orient the layers for maximum strength)
Where is the part used and which surface must look the cleanest?

✓ We will orient the part on the build plate and configure print settings based on your answers.

3 Supports

Automatic (recommended)The 3D view highlights all surfaces that may require support. Exact supports are reviewed and configured for the best result before printing. No supportsIf the model prints fine without supports.

✨ Smooth & stronger support surface – dedicated interface material (Support Interface, Z=0 mm)The support contact layer is printed on a dual-nozzle printer using a separate release material (e.g. PETG ↔ PLA) with zero air gap (Z=0 mm). This leaves the supported surface smooth and dimensionally accurate, and adds significant strength on thin or curved parts because the bottom layers are pressed firmly together rather than printed loosely in the air. 💡 For thicker parts where the underside appearance does not matter, you can leave this unchecked – standard single-material supports are much more affordable.

Compare Our 4 High-Temp Carbon Fiber Composites (186–227 °C)

Engineered for metal replacement, motorsport engine bays, industrial jigs, and aerospace UAV structures

🦾 PPA-CF (227 °C) – Flagship Metal Replacement

Polyphthalamide carbon-fibre (PPA-CF) is +48% stronger and +102% stiffer than PA6-CF with minimal moisture sensitivity and 227 °C heat deflection.

⚙️ PA6-CF (186 °C) & PAHT-CF (194 °C)

PA6-CF delivers unmatched impact and vibration damping for heavy brackets. PAHT-CF absorbs 70% less moisture for tight tolerances in wet/hot environments.

🪨 PET-CF (205 °C) – High Stiffness & Zero Creep

Industrial carbon-fibre PET offers 205 °C thermal stability, near-zero water absorption, and our lowest price point in the 200+ °C class.

Frequently asked questions

How do I choose between PET-CF, PA6-CF, PAHT-CF, and PPA-CF?

• PET-CF (€70/kg, 205 °C): stiff, moisture-proof, best value. • PA6-CF (€95/kg, 186 °C): highest toughness under shock and vibration. • PAHT-CF (€110/kg, 194 °C): low moisture absorption nylon. • PPA-CF (€155/kg, 227 °C): ultimate metal-like stiffness and strength.

Can PPA-CF or PA6-CF replace CNC-machined 6061 aluminium brackets?

In many structural brackets, fixtures, and mounts, a thick-walled PPA-CF or PA6-CF part replaces machined aluminium at half the weight and a fraction of single-piece CNC cost.

Can I test the calculator with a sample PPA-CF bracket?

Yes! Click the "🛠️ Bracket (PPA-CF)" button inside the upload box to inspect a real structural bracket right in your browser.

Are all four carbon composites in stock?

Yes – we keep PA6-CF, PAHT-CF, PET-CF, and PPA-CF in stock and print them in actively dried, enclosed chambers.

What wall count and infill should I select for structural carbon parts?

Use the "Strong" preset (4 walls + 40% gyroid infill), or 5–6 walls under Advanced Settings for maximum bolt-hole bearing strength.
