🛠️ 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.

Online STL 3D Printing Made Simple

STL (Stereolithography) is the universal 3D printing mesh format exported by every CAD tool

🔍 Live Mesh & Dimension Verification

Both binary and ASCII .STL files are supported. If your CAD exported in inches instead of millimetres, convert units with one click or measure hole diameters (Ø) directly inside the interactive 3D viewport.

🛠️ Lay-on-Face & Automatic Overhang Analysis

No slicer software required. Use the Lay-on-Face tool to orient your STL for maximum layer strength and immediately preview areas steeper than 45° that require support material.

⚡ 15+ Plastics & Carbon Composites

Choose from standard PLA and tough PETG to UV-stable ASA and industrial carbon/glass fibre nylons (PA6-GF, PA6-CF, PPA-CF). Instant volume discounts apply automatically.

Frequently asked questions

Why does my STL file appear tiny or huge after uploading?

STL files store raw numbers without unit metadata. A file modelled in inches imports 25.4× smaller in millimetres. Click the "inch → mm" button under Advanced Settings or type the exact target dimension in the 3D view.

What STL export resolution should I use from SolidWorks / Fusion 360?

Use "High" or set surface deviation (chord tolerance) to 0.01–0.05 mm. This keeps cylindrical holes and fillets smooth without faceted flat spots.

Is my STL file kept private and secure?

Yes. Initial geometry analysis runs 100% locally in your browser. Your STL is only uploaded over encrypted HTTPS when you add the part to your shopping cart.

Can I add an embossed or engraved logo onto my STL file?

Yes! Once your STL is loaded, use the "Logo on Part (SVG)" panel to place, scale, or wrap your vector logo around flat or cylindrical surfaces before ordering.

What is the maximum build size for STL printing?

Our enclosed industrial FDM printers accommodate single-piece STL models up to 325 × 320 × 325 mm (and 256 × 256 × 256 mm on standard chambers).
