CRAFTRUDER factory concrete 3D printer — 01Factory production

CRAFTRUDER concrete 3D printer operating on site — 02On-site printing

100,000 m² of walls printed

1,000+ completed 3D-printing projects

Up to 4 print heads on a single printer

10 mm maximum aggregate size

01 / SYSTEM

Two scenarios. One machine.

Two business models let you adapt your product range to market demand and operate year-round.

Factory concrete printing configuration from the CRAFTRUDER catalogue

INDOOR / PREFAB

Factory production

Multiple components are printed layer by layer on a prepared print bed. Dual-extrusion modules, conveyor feeding and underfloor heating create a consistent, repeatable production cycle.

On-site concrete printing configuration from the CRAFTRUDER catalogue

OUTDOOR / ON-SITE

Printing directly on the foundation

A single extruder, increased gantry height, a concrete pump and a concrete batching plant make it possible to print the shell of a single-storey building directly on site.

03 / PRODUCTION LINE

Concrete delivery without costly consumables

In a fixed factory setup, the mix is transferred by conveyor. For outdoor use, the conveyor is replaced with a concrete pump.

Steam-curing chamber

A sealed retractable chamber for controlled curing.

Steam generator

Steam curing and heating for aggregates, water and the print area.

Mixer and conveyor

Planetary mixing and smooth-belt concrete feeding.

Concrete pump

Material delivery for on-site printing.

04 / PRODUCTIVITY

More print heads increase output

Actual output depends on layer parameters, geometry, pauses, non-printing travel, mix design and shift organisation.

0.3 m/s extruder travel speed

0.3 m³/h standard dual module · approx. 6 m²/h

0.6 m³/h X4 configuration · approx. 12 m²/h

06 / MATERIAL

Locally sourced materials

The core printing technology and mix design are adapted to local sand, cement and graded aggregate. The reference formulation below uses 2–8 mm crushed stone.

REFERENCE FORMULATION

What goes into printable concrete?

This one-page guide shows a tested starting composition by mass. It uses ordinary mineral components rather than a proprietary dry mix.

32.12% crushed stone, 2–8 mm 32.12% sand 21.42% cement, CEM II/A-LL 42.5 R or equivalent 14.28% water 0.06% air-entraining plasticizer

Reference only: the final recipe, water demand, admixture dosage and aggregate grading must be tested and adapted to local materials, climate, delivery distance and the selected product.
