CONCRETE
3D PRINT
SYSTEM

India's precision concrete extrusion printer, purpose-built for laboratory research — develop and validate cementitious mixtures, print test specimens, prototype structural elements, and characterise material behaviour across mortar, geopolymer, UHPC, and fibre-reinforced paste systems.

Engineering Features

BUILT FOR
THE RESEARCH LAB

Every capability is designed around one question: what does a materials scientist actually need when developing a new cementitious mix?

Flow-Controlled Extrusion

Precision Pressure Control

0.1 – 10 bar per-nozzle

Each nozzle has an independent servo-pneumatic pressure regulator with ±0.05 bar repeatability. Dial in the exact extrusion pressure for any paste viscosity — from fluid self-compacting grout to stiff fibre-reinforced mortar — without manual nozzle swaps.

0.1 – 10 bar range
±0.05 bar accuracy
Real-time pressure logging
Programmable ramp profiles

Research Applications

WHAT YOU
CAN RESEARCH

From cementitious mix validation to geopolymer sustainability studies — real research workflows on the Concrete 3D Printer.

Accelerate Cementitious Mix R&D

Replace slow hand-cast batching cycles with systematic, reproducible printed specimens. Print a full w/c ratio or admixture dosage study in a single session — consistent geometry, controlled deposition.

Research Protocol 1

Water-to-Binder Ratio Study

Print identical 40×40×160 mm prismatic specimens at 5 different W/B ratios (0.25–0.45) in one session. Test compressive and flexural strength at 1, 7, 28 days against matched cast controls.

Material
OPC CEM I 52.5R mortar
Output
W/B vs. strength + buildability curve
Research Protocol 2

Admixture Dosage Optimisation

Systematically print specimens at 0.1–1.5% VMA (viscosity-modifying agent) dosage intervals. Correlate print pressure and strand spreadability with 28-day compressive strength.

Material
Mortar + HPMC VMA
Output
Optimal VMA dose for print + strength
Research Protocol 3

SCM Replacement Study

Print specimens with 0, 10, 20, 30% cement replacement by fly ash, silica fume, or GGBS. Automated layer-count vs. deformation (buildability) protocol included.

Material
OPC + fly ash / silica fume / GGBS
Output
Printability vs. SCM% matrix
