FAQ & Design Guides

We price by the weight of the final print — not by volume or time estimates. Upload your model to our instant quote tool to get an exact price in seconds. Prices start from a few euros for small parts. The quote includes material cost, machine time and a one-time €9.50 setup and handling fee.

We accept STL and 3MF files — the standard formats for 3D printing. You can export these from any CAD software including Fusion 360, SolidWorks, Blender, Rhino and Tinkercad. 3MF is preferred as it preserves scale and orientation.

Standard orders ship within 3–5 business days from order confirmation. Rush orders are available and ship within 2 business days. Actual print time depends on the size and complexity of your model — our quote tool estimates this automatically.

Yes — free pickup is available at our studio at TT Vasumweg 101-15, 1033SG Amsterdam. Please contact us to arrange an appointment before coming by.

Yes, we ship worldwide via PostNL. Rates vary by destination and package weight — see our pricing page for an overview. Exact shipping cost is confirmed with your order.

Our largest FDM printer handles parts up to 370 × 370 × 370 mm. For larger parts we can split the model and join the pieces after printing. SLA printing is available for smaller, high-detail parts up to approximately 200 × 125 × 200 mm.

Yes — you can upload multiple files in a single quote request. Each file can have its own material, color and settings. The €9.50 setup and handling fee is charged once per order regardless of how many parts you include.

After we confirm your order we will send an invoice. We accept bank transfer (IBAN) and online payment. Payment is due before we start printing.

The minimum recommended wall thickness for FDM is 1.2 mm — this is 3 times the standard 0.4 mm nozzle diameter. For functional parts that need to handle load or stress, 2.0–3.0 mm is more appropriate. Walls thinner than 0.8 mm may not print reliably. Always design walls as multiples of 0.4 mm for best results.

FDM can print overhangs up to approximately 45–50° from vertical without support structures. Beyond 45°, the layers start to droop and surface quality degrades. Perfectly horizontal overhangs (90°) require supports. When designing, try to orient features so they stay within the 45° rule — chamfers instead of fillets, and angled instead of horizontal bridging.

Bridging is when the printer spans a gap between two supported points without support structures underneath. FDM can reliably bridge gaps up to about 50–80 mm depending on material and cooling. PLA bridges best of the common materials. For longer spans, add a gentle arc to the underside — a slight curve prints much better than a flat horizontal bridge.

Due to the layer-by-layer process, round holes in FDM tend to print slightly undersized — typically 0.2–0.4 mm smaller than designed. For holes that need to fit a shaft or bolt, add 0.2 mm to the diameter in your model. Vertical holes (axis parallel to the print direction) print most accurately. Horizontal holes may need supports inside them for diameters above 10 mm.

For parts that need to fit together, design a clearance of 0.2–0.3 mm per side (0.4–0.6 mm total gap). For snap fits and press fits, 0.1–0.15 mm per side works well in PLA and PETG. Tight fits in ABS require slightly more clearance because ABS warps slightly during cooling. Always print a small test piece first when tight tolerances matter.

Yes — fillets (rounded inside corners) significantly improve layer adhesion at stress points and make parts stronger. A 1–2 mm fillet on inside corners is good practice. Chamfers (angled edges) on outside top edges reduce the "elephant foot" effect where the first layers spread slightly. On bottom edges, a 45° chamfer also eliminates the need for supports on those features.

Warping is most common in ABS, ASA and large flat parts. To reduce it: avoid large flat bottom surfaces by adding a slight bevel or raft in your slicer; orient the part so the largest face is on the build plate; use materials like PLA or PETG for parts where warping is a concern; and avoid sudden changes in cross-section area between layers.

For display models and non-functional parts, 10–20% infill is sufficient. For general-purpose functional parts, 20–30% gives a good balance of strength and material use. For high-stress parts like brackets or mechanical components, 40–60% or more is recommended. Above 60% the strength gain per added material decreases significantly — solid walls and more perimeters often give better results than very high infill.
