Introduction
Paul's research focuses on automation in construction, specifically on how robotic technology and advanced manufacturing can minimise and reduce design waste from current construction practices. He researches flexible and reusable formwork for concrete casting and holds a patent technology successfully commercialised through a start-up company. In addition, his research also focuses on the cognitive engagement of digital technology in design practice and education.

Chapter
In the early twentieth century, acoustic shells were primarily conceived as permanent structures, generally made in reinforced concrete. Architects like Candela and Niemeyer exploited the high density and plasticity of concrete to realise forms that could reflect sound efficiently. However, building doubly-curved shapes required laborious construct...

This paper discusses the design, fabrication and operational workflow of a novel hot-wire cutter used as an end effector for a robotic arm. Typically, hot wire cutters used a linear cutting element which results in ruled surfaces geometry. While several researchers have examined the use of hot wire cutter with cooperative robotic arms to create non...

This paper presents a novel advance digital fabrication method to produce doubly curved concrete panel with no immediate waste as a facade system. Using a bespoke CNC adjustable mould frame system coupled with robotic trimming techniques, the research examines the streamlining of data within a cohesive fabrication workflow. The paper concludes by r...

Casting is one of the most widely used construction techniques. Complex geometries produced via computational design processes are not readily achievable through traditional rigid formwork and are subject to increased material waste. More suitable casting techniques are required to represent digital design output efficiently. This article presents...

This paper discusses the design and fabrication of a novel in-situ fabrication system for building cladding envelope. The construction industry has utilised automation in onsite construction for many decades. This research examines how through the automation process, different construction techniques can be combined to generate a new system that is...

This paper examines tool making as a form of design research. With the widespread availability of open-source electronic prototyping platforms and its knowledge, designers are no longer the end user of emerging technology and digital toolsets. Instead, we see a surge of designers dappling in the discipline of software, material and mechatronic engi...

Fabricating complex curvature in concrete panel typically required unique one-off formwork which is usually computer numerically controlled (CNC) milled, generating enormous waste as a by-product. What if, we can produce complex curvature in concrete with minimal or no immediate construction waste? This paper presents a novel machine designed by a...

With the wide spread adaptation of digital technology in the design discipline, there is a need to understand the role of technology in design teaching. In this chapter, we will examine the role of technology as probes, prototype, and toolkits and ask how this facilitates a more holistic learning process. “Design problem” is by its nature multi-fac...

The term ‘Digital Craft’ is commonly applied in the context of craft as exercised with the aid of digital technology. If the application of digital tools and techniques merits the term digital craft, then where does the craft lie in Computer Numeric Control (CNC) making? This article takes the position that craft practice is rooted in the relations...

Project
This project examined craft in digital fabrication and design through an in-depth understanding of the role of tool, material and techniques. The project explores the idea of design repertoire and how technology can become an agency of design. Research is tested through design research.

Project
PAM is a numerically controlled (NC) variable ruled-surface mould design which produces doubly curvature surface panels. The aim of the project is to eliminate the need of wasteful mould design in the manufacturing of panelised system whereby a single adjustable mould can produce highly customisable geometry using NC technology. PAM utilised a CNC deformation process developed at the Melbourne School of Design. An early iteration of PAM (v.1) produces 32 unique hyperbolic paraboloid surfaces using Echopanel™, a recycled PET plastic acoustic panel to construct a free standing acoustic enclosure suitable for privacy booth or meeting room pod in an office environment. Current research is focused on expanding the material repertoire with this manufacturing technique including concrete and solid surface material. Typically, most smooth double curvature surfaces are broken down into conveniently sized panels for ease of manufacturing. Such surfaces are often non-developable unless based on single ruled-surface geometry. Traditionally, the double curved surface has to be approximated through panelization to form developable surfaces either as triangular or planar quadrilateral surface. Non-developable surfaces can only be achieved through stretching the flat plane through physical deformation process such as stamping (similar to a car body), casting or injection moulding using thermal plastic or concrete. These methods required unique mould to be manufactured for each surface. The ability to produce customisable forms using a single adjustable mould can therefore greatly reduce the cost and efficiency in the production of doubly curved panels. The significant of this research is in developing industrial application using NC technology in the fabrication of complex doubly curved surfaces. It is a unique manufacturing procedure which has the potential to provide a cost effective solution to the current manufacturing methodology as well as reducing material waste in mould design. In addition, knowledge gained in the development of this research can be applied to other moulding process to develop fabrication method in dealing with complex geometry.
