Design for additive manufacturing

Every variant
print-ready.

Wall thickness, clearance and overhang angle sit in the model as rules. Change a dimension and the geometry recalculates — as a watertight solid that goes into the slicer without repair. Colleagues, customers and production pull their own version straight from the browser.

Z 01 EXAMPLE

Printed projects
that recalculate.

Two complete printed products rather than demo objects: a modular marble run whose elevator, switch and helix are real mechanics, and a drive chain that comes off the build plate already articulated. Both take their fits from parameters instead of rework.

KINETIC PRINT PROJECT

Modular marble run

Ball diameter, module grid, track width, helix turns and elevator height are parameters. Print clearance acts on every clip connector at once — the run works in the browser before the first print starts.

Module grid 120–180 mm, ball ⌀ 16–24 mm
Print clearance 0.20–0.50 mm per side
Chain elevator, switch, helix and loop as mechanics

ARTICULATED OFF THE PLATE

Print-in-place drive chain

A roller chain built like the real thing: two outer plates joined by through pins, two inner plates between them, rollers in the tooth slot. Chain size follows DIN 8187 — the generated sprocket uses the DIN 8196 tooth form, and the printed chain also runs on a commercial sprocket of that size.

Chain sizes 06B to 24B, 6 to 60 links
Joint clearance 0.20–0.50 mm, separation gap in layers

Z 02 FROM PARAMETER TO PRINT FILE

Model less.
Print more.

The expensive time in 3D printing rarely sits in the printer. It sits in remodelling every size, in repairing meshes, and in the second print because the fit came out too tight. A parametric model settles all three once.

01PARAMETERISE THE PART

Dimensions, grids and interfaces go in as parameters — the part follows from them instead of being redrawn for every size.

02SET THE PRINT RULES

Wall thickness, running clearance, overhang angle and minimum radii are rules inside the model. They apply to every variant without anyone having to remember them.

03PULL THE VERSION YOU NEED

Every version delivers watertight solids: STL and 3MF for the slicer, STEP for CAD, a parts list for procurement.

RESULT FOR ENGINEERING

A file that prints — not one that has to be repaired first.

No mesh patching, no re-measuring fits, no forest of variant files. The geometry comes out of rules that were set correctly once.

Z 03 PRINTABILITY IS A RULE, NOT A REMINDER

What the printer needs
lives in the model.

Four rules decide whether a part fits on the first attempt. In a parametric model they are stored once and hold for every size — not just for the one that happened to be drawn.

01WALL = n × NOZZLE

Walls follow the nozzle

Wall thickness is calculated as a multiple of the nozzle width, not estimated. The slicer finds full perimeters instead of half extrusions.

02FIT 0.20–0.50 mm

Clearance instead of rework

Moving fits get their clearance per side as a parameter. Clip connectors, bearing seats and lids fit after printing — not after sanding.

03OVERHANG ≤ 45°

Overhangs without supports

Overhangs stay within the angle the process carries. Chamfers replace support structures where supports would ruin a visible surface.

04Z ORIENTATION

Build direction and shrinkage

Build direction is part of the model: load path, layer adhesion and shrinkage go into the geometry instead of being compensated afterwards.

Change the nozzle, the material or the process and these rules change in one place — every version of the part follows.

Z 04 FROM ENGINEERING PRACTICE

From a parameter
to a printed part.

confBuild builds printed products as connected assemblies. Change one dimension and mounts, connectors, brackets and the parts list follow — with nobody remodelling anything.

Z 05 CAD KERNEL

Not a mesh remix.
Real parametric
geometry.

The confBuild CAD kernel calculates solids from parameters and design rules — with real fillets, chamfers, bores and threads. Not a mesh remix from a parts library, but geometry that reaches the slicer watertight and production dimensionally correct.

Watertight

Solids, not patched-up meshes — the export slices without repair steps.

Print-aware

Wall thickness, clearance and overhang follow the rules you set once.

Useful downstream

STL, 3MF, STEP and a parts list feed slicer, CAD and production.

Browser-native

Interactive 3D without a local CAD installation.

Z 06 PARTS THE TEAM KEEPS REUSING

Built once.
Printable by anyone.

A parametric part — bracket, enclosure, fixture — is available to everyone in the browser: enter your own dimensions, download the print file, print. No CAD licence and no variant folder to maintain on a shared drive.

Parameterise the part

A part is described once with its design and print rules instead of being maintained across twenty variant files.

Share it with the team

A link is enough: colleagues, suppliers and customers open the part in the browser.

Enter your dimensions

Everyone sets the dimensions they need — the rules for wall thickness and clearance stay in force.

Download the print file

STL, 3MF and STEP go straight into slicer and CAD, with no repair step in between.

Z 07 MORE THAN A QUICK PREVIEW

A tool for
engineering.

Design, review and print file come out of the same parametric model — from the first part to your own catalogue.

01◇

Variants without remodelling

One parameter change produces the new size — including mounts, connectors and parts list.

02≡

Print rules that hold

Wall thickness, clearance and overhang angle apply to every version, not just the one drawn first.

03⌁

Share parts

Colleagues, suppliers and customers open the part in the browser, with no CAD workstation.

04◎

Reuse the data

STL, 3MF, STEP, parts list and parameters carry on into slicer, CAD, ERP and production.

Z 08 FOCUSED REMOTE PILOT
