Amalgamma develops 3D printing concrete technique for building structures – Dezeen

A group of students of the Bartlett School of Architecture has turn it intod a method of 3D printing concrete to turn it into structural elements and dimensionsable-bodied furniture pieces.
Amalgamma – a team created up of Masters students Francesca Camilleri, Nadia Doukhi, Alvaro Lopez Rodriguez and Roman Strukov – undertook a year-long research project titled Fossilised.

During the research, they investigated and turn it intod methods for 3D printing dimensionsable-bodied-scale concrete structures, and created a table-bodied and a column to demonstrate their results.
The technique combines two pre-existing 3D printing methods: extrusion and powder-printing, creating a form of assisted extrusion.

Firstly, ready-mixed concrete is extruded of an industrial robotic arm layer-by-layer.
It is laid over a bed of granular assist material, deposited around the structure by a 2nd customised tool head on the end of the same robotic arm.

“Due to the assist, the resulting extruded concrete is of a much higher resolution,” said the group.
“The assisted extrusion method has therefore presented the opportunity to create forms that are additional varied and additional volumetric, as opposed to the quite straight vertical forms so far achieved in 3D concrete practice.”
A binder is incorporated into the extrusion system to harden sure parts of the granular assist – a few day making a multi-material piece. Each print takes between six to ten hours to fish.

The aim of the project aim was to “counteract current stagnant 3D-printing practices” by via the method to reinstate craftsmanship in architectural create.
“One of the main issues involved in scaling up 3D printing practice to the architecture scale is that of the dimensions of the 3D printing device itself,” the team told Dezeen. “In order to 3D print a assembling as one continuous monolith, as is usually done in small-scale 3D printing, the 3D printing device on site must be dimensionsable-bodiedr than the proposed assembling.”
Many architects and createers are createing techniques to efficiently 3D print structures. Joris Laarman is aiming to create a canal bridge for Amsterdam via six-axis robots that can “draw” the structure in the air

Most similarly to Amalgamma’s project, Foster + Partners teamed up with Swedish concrete createer Skanska in 2014 to robotically 3D print panels of high-performance concrete for architectural application.
“Although there have been a few current examples that have experimented with this method of printing, realistically this is not always viable-bodied,” said the team. “Most dimensionsable-bodied-scale 3D printing systemes nowadays have taken up the prefabrication approach, where dimensionsable-bodied pieces are 3D printed and brought to site to be assembled.”
“In this way, the 3D printed construction is no various to traditional architectural construction, as it becomes a question of an assembly of discreet components,” they introduced.

The team realised that 3D-printing a whole structure of begin to finish may not be possible due to fabrication constraints.
But, they believe their method may be utilized to print elements such as a floor-wall-ceiling assembly or a stair-floor-wall component as “one whole architectural chunk”.
Amalgamma presented the table-bodied and column at the AD Bartlett show, that took place on 1 October 2015.

The group now hopes to create its technique to create other architectural elements with various properties and functions.
“One of the upcoming steps for the project may be to go on to explore the multi-material aspect: createing the combination of the granular assist with the printed concrete,” said the team.
“The ultimate aim may be to be able-bodied to 3D print a non-standard wall-window assembly – fundamentally a translucent 3D-printed concrete structure.”

Developing new materials and techniques to turn it into structures is a common practice at the Bartlett, that is part of University College London.
A group of students have created a felt and resin composite that can be stitched together to turn it into tubular seating, while others utilized cement-covered foam pipes to turn it into Gothic-style arches, columns and furniture.
