ICON Vulcan – 3D Construction Printer

Vulcan is ICON’s 3D printer designed specifically to produce resilient single-story buildings faster, more affordably, and with more design freedom. It has a printing capability to approximately 2,000 square feet. It has an adjustable width (to accommodate different slab sizes) and is transported in our custom trailer with no assembly required.

World First 3D Printed House

The Vulcan features intuitive tablet-based controls, remote monitoring and support, onboard LED lighting for printing at night or during low-light conditions, and a custom software suite ensuring set-up, operations, and maintenance are as simple and straightforward as possible.

Vulcan comes with an integrated tablet-based operating system for controlling every aspect of print operations via an intuitive, simple, and beautiful user interface.

Tablet App


ICON’s proprietary Portland Cement-based mix is a closely guarded secret that enables us to rapidly print homes that are beautiful, structurally sound, and cost effective.

Advanced formulation

We’ve combined easy-to-source raw materials with advanced additives, enabling our material to be sourced from anywhere in the world while retaining material science super powers

Structural integrity

Lavacrete has a compressive strength of 6,000 psi, well above the strength existing building materials.

Thermal envelope

Wall system has been designed to take advantage of the high thermal mass of concrete to maximize both comfort and efficiency.


Unlike traditional building materials, Lavacrete is able to withstand extreme weather conditions to minimize the impact of natural disasters.

Rapid build times

Lavacrete can be printed at high speeds while retaining form, enabling homes to be built faster, keeping construction projects on schedule and on budget.

Magma material delivery system

ICON’s Magma system is the first end-to-end automated material delivery system for use in 3D printed construction. Using one of ICON’s proprietary Lavacrete blends (specific to climate and location) the Magma system mixes Lavacrete, additives, and water automatically from built-in reservoirs. The Magma system then supplies the ready-to-print Lavacrete to the Vulcan II tuned to a specific temperature, humidity, altitude, and speed.

With no manual measuring, mixing, or dumping, it’s as easy as the push of a button.
