‘Testing The Machines Of A Third Industrial Revolution’ Cross Section Presentation Model, Abhi Chauhan

Abhi (33)

This project was completed in the final weeks of the last academic year by 6th year MA Student Abhi Chauhan. The project is the follow on to the 1:100 section we featured several months back. What is particularly appropriate about the styling of this project is the subject matter or the site. Being a 3D Printing Manufacturing facility of the future means no better method of production that the technology in question. This is definitely something to consider when devoting yourself to a major project like this – for example, if you are building an eco-concious design then that ethic should carry through to your presentation and thus model construction. This project sticks to its purpose through and through.

Abhi has been since graduated and started a full time position at Grimshaws in London. We wish him all the best in his future career!

This piece will be on display as part of our B.15:45 Exhibition so be sure to have a look in person.

Abhi has kindly written us this extensive account of the theory and construction methods he used in this stunning final piece. Enjoy!

This model is a final exhibition 1:50 sectional model. The slice is located through a key component of the building scheme titled ‘The Machines Of A Third Industrial Revolution’ The model slice – in detail depicts the processes of 3d printing of 1:1 architectural components, to be tested on a stalled concrete frame bounding the site. The design of the facility is such that it sits into a trench in the ground and features a folded roof structure which integrates a 3d printed park at ground level with the industrial processes of the facility within. The scale of the facility has been designed to be oversized, to deal with the variety of large scales that are needed in the manufacture of components for the construction industry.

The model builds upon the 1:100 sectional model completed earlier this year, and takes on a similar aesthetic to that of a cross section through a large industrial machine hanging of the walls of the facility.

The model has been constructed with a variety of different techniques.

The base has been CNC cut from x15 18mm mdf sheets layered and glued together. This method, although not the most cost effective meant that each layer of the base could be designed to incorporate slots and grooves within for housing of the various components that would eventually complete the model.

The red structural parts forming the portal steel frame structure hung within the trench were all constructed in 3ds max and then 3d printed on the ABS printer. These parts were then spray-painted to get the final red finish seen. Other components that were printed, include some of the facade components, and the series of storage tanks and pipes to the right of the trench. This method of manufacture was chosen sue to the time constraints, the subject matter of the project, and the complex shape of some of the parts.

The roof was also 3d printed and a shelling script in grasshopper gave the folded structure a thickness to make watertight for 3d printing. This part was the most challenging to construct and after a variety of failed tests the part was printed at Hobs due to their larger printer beds (up to 1500mm wide) which allowed for the part to be printed as one component. Finishing the roof are a series of card panels (depicting a metal skin) which were laser cut and engraved. These were bonded to the 3d printed structural roof frame using spray mount.

The material archives (in white) set into the base of the model were the last parts to be 3d printed on the model, and were done on the powder 3d printers. These constructs were notoriously fragile and once installed in the base had their edges and portions of their rebuilt in white pollyfilla.

The remaining components making up the model have been formed from either 2 or 3mm clear acyclic. For example the 3d printers on the -2 level have been laser cut form a mixture of 2 and 3mm acrylic and then assembled to snap fit and slot together to avoid gluing. This clear aesthetic was chosen for a variety of the model parts as can be seen.

The landscaped elements including the cranes and gantry and the main internal staircase were all laser cut from 2mm mdf. These part were all spray painted to the final grey and black finish shown.

The facade skin (resembling an ETFE system) was vacuum formed over a 3d printed mould. The mould was designed with groves in it and as such were expressed in the final plastic shells.

Before any parts were manufactured every part was modelled in 3d and then assembled to create a master digital model. (see image) Due to the large amount of parts on this model this was necessary to eliminate any unforeseen mistakes which would be harder to rectify once parts had already been cut.

Each part of the model was treated as a mini project i.e. the main facade, the main stair case, the 3d printers on the ground floor, etc. Once these were all assembled and sprayed the whole model was put together like a giant jigsaw. Due to the fact that almost every part was digitally fabricated there were few tolerance errors during final assembly.

The model took approximately 3 weeks to translate from an actual section into model drawings and then 3 weeks to get all the parts cut and painted and a final week to assemble together.

‘Exchange Parade Theatre’ Context Model, Rachel Jenkins

Just completed design development model, this 1:500 context model aims to show how this proposed theatre design will sit within what is currently an urban car parking space. The model includes subterranean levels and roadways that make up the different site levels. At this stage the model can be disassembled to allow for possible design changes to be discussed with RachelÒ€ℒs tutors.
