Print hydraulic flange parametric & 3D: bolt circle, hole pattern & pipe socket
You are looking for a Flange made to measure - without CAD? With our Flange configurator legst you Flange diameter, Thickness, Bolt circle / hole pattern, bores-Ø and Pipe ID/OD create the STL file and lässt den Print hydraulic flange 3D. Ideal for prototype, adapter flange, test arrangement or transition from hose to pipe.
What is it?
A hydraulic flange connects Tube, Pipe or Aggregate about a Hole pattern (bolt circle). The parametric flange creation is worthwhile if standard parts do not fit: adapterflansch, Transition flange, Reyouzierflansch, Sensor flange or prototype with custom pipe socket. Our Online-configurator creates a print-ready STL - fast, clean and without CAD.
You need these dimensions for parameterization
- Flange diameter (outer diameter) & Thickness - Installation space, stability, screw length.
- holekreis-diameter (BCD), number der boreen and bores-Ø - results in Drilling pattern.
- Tube outer diameter (OD), Tube inner diameter (ID) and Tube length - define the Pipe socket.
Tip: Measure the mating flange with the caliper gauge. If you are unsure, start with conservative tolerances and a short test print.
Standard values & tolerances (bores, sealing surfaces, pipe)
| Feature | Guideline | Note |
|---|---|---|
| bores-Ø | Screw Ø + 0.2...0.6 mm | e.g. M6 → 6.4–6.8 mm (allow for printing tolerances) |
| Sealing surface | Layer height 0.12-0.20 mm | Print plan, fine sand / matt seal if necessary |
| Tube wall thickness | ≥ 2.0-3.0 mm | More perimeter increases tightness & stability |
| Centering | Centering collar / locating sleeves | Facilitates assembly, saves screws |
Note: Values for FDM-prototypes and Low pressure. For High pressure and safety-relevant We coordinate material, orientation and wall thicknesses individually with you.
Sealing concepts: O-ring, flat gasket, centering
- O-ring groove (rectangular or according to DIN dimensions): defined sealing line, repeatable.
- Flat gasket (e.g. fiber, rubber, TPU): tolerant to unevenness.
- Zentrierband and Fitting sleevessecure position, lower shear forces on screws.
Material selection & print settings
- PLA: prototype, Innenraum, sehr gute Detailtreue.
- PETGtougher, more temperature resistant - more versatile Allroander.
- ASA/ABSuV-resistant or robust - for outdoor & elevated temperature.
Settings: Layer 0.16-0.24 mm, 4-5 perimeter, infill 20-40 % (depending on load). Flange flat on the bed, pipe socket upwards - this ensures clean sealing surfaces.
Step-by-step: From the idea to the STL
- Measure the mating flange: bolt circle diameter, hole diameter, hole count, flange diameter and thickness.
- Choose the tube outer/inner diameter and length to match the medium and hose or line.
- Define sealing concept: O-ring groove, flat gasket, centering.
- Parametrisieren → preview checken → export STL.
- Order a 3D print – we deliver professional quality.

FAQ
How accurate is the drilling pattern from the configurator?
Tolerances in the tenths range are realistic for FDM prints. Select bore Ø slightly over screw Ø to obtain assembly clearance.
Replacement for standard flanges (DIN/EN)?
We manufacture to your exact specifications. For standard-compliant applications, please contact us - we will check drilling patterns/dimensions and advise on suitable Process/Materials.
Can I switch to metal later?
Yes, use 3D printing for prototype & testing; upon approval we can Derive drawings for CNC/metal construction.
