Title

Thermomechanical Modelling of 3D Printed Porous Structures for Large Scale Printing

Speaker

Kevin Silver (PhD Candidate)

Abstract

Supervisor/s: Johan Potgieter, Richard Archer, Khalid Arif, Mark Taylor
Convenor: Robyn Phipps
Panel: Liqiong Tang, Xiaowen Yuan

Additive manufacturing (AM) allows designers to build 3D parts of almost any geometry and streamline the process of moving from initial design to prototype in a protracted timeframe. However the existing processes/technologies are limited to small size parts due only to high resolution of the generally produced designs. If a very large part with typical layer resolutions of 0.025mm to approximately 0.2mm is produced, the time required for making such a part will be prohibitive. In addition, the material costs (ranging from tens to thousands of dollars per kilogram) will excessive and the machine size will need to be gigantic. An example of a large scale AM is the printing of milk storage vat insulation and support structure.

As per dairy industry regulations, milk must be stored at a low temperature in a vat after collection from cows. Currently the milk vats are thick walled stainless steel tanks, which are expensive to purchase and require a great deal of insulation and constant cooling to keep the milk at the required temperature. The requirements for thermal insulation and mechanical strength are not easily achievable for passive cooling through conventional manufacturing technologies. Therefore AM offers a great opportunity to achieve mechanical and thermal properties as and where needed.

Unfortunately, AM cannot be directly applied unless mechanical and thermal properties are well understood through experimentation or simulation. The sheer size of the large prints makes it very challenging to test in physical forms and thus leaves simulation the only viable way to ascertain the potential of AM for large applications. However numerical models of 3D printing (3DP) from powder materials (e.g. nylon, stainless steel) are not available, particularly due to the porous nature of the process.

This research is aimed at creating or modifying an existing numerical model to study thermomechanical properties of printed structures. In this regard, inspiration is gleaned from rocks and their models prepared by geologists. Rocks are formed by a similar process to 3DP in nature over long periods and are considered porous, similar to 3DP.

In the first year (as a pretext to the above) milk vat insulation using an appropriate large scale AM technology was studied. The main focus was on optimisation of the structure of the vat insulation and support, and selection/preparation of a lightweight low-cost material. The structures considered were based on the structural and thermal requirements. Among many possibilities, fractal tree-like structure presented an encouraging option for its thermal resistance. This structure showed minimal to no heat loss at thicknesses of around 100mm. However it failed under the loads produced by the buckling of a stainless steel tank. An alternative structure being studied is the honeycomb structure for its strength, which is strong enough to overcome the buckling of the tank. The thermal resistance of the honeycomb however is poor. By combining the benefits of various structures together into a multi-material single structure, the inner section of the structure with thermal resistance and the outer section for mechanical strength can be optimised. A poster on this research was recently presented at MaD while a journal paper on the effects of a heated environment on the properties of an AM part is presently being prepared.

An ideal structure requiring minimum material and printable from existing materials is presently not feasible. However, this research is continuously exploring the possibilities through simulations and experimental testing. The optimum solution for the current problem will be created through a model of the unit block adapted from geological study. This porous thermomechanical model will utilise the similarities of rocks and 3D printed parts to create the model. It is expected that an optimum solution for the current problem will be produced which will be universally applicable to other large-scale printing solutions.

Title

Novel Bioprinting Technologies for the Production of Complex Collagen Tissues

Speaker

Juan Schutte (PhD Candidate)

Abstract

Supervisor/s: Johan Potgieter, Steven Dirven, Xiaowen Yuan, Katie Sizeland
Convenor: Khalid Arif
Panel: Frazer Noble, Liqiong Tang

This report examines an opportunity for 3D printing of structured collagen fibres. First, it visits existing literature to develop an understanding of the current capabilities of bio-printing-based tissue engineering, from this the dependency on pressure and heat for high resolution as well as the lack of fibre fabrication methodologies is highlighted as limitations for complex collagen tissue production.

Collagen was reviewed and the cornea is discussed as a structural benchmark for the project. The corneal stroma is identified as the fundamental structural component from which the desirable manufacturing characteristics are derived namely; collagen expressed as nanofiber, this fibre occurring in a highly ordered/aligned manner in overlapping sheets(lamellae) of varying orientations.

Nanofiber production technology was assessed which emphasised electrospinning as preferable given its ability to generate nanofibers of this protein and the capability to adjust fibre and alignment properties with relative ease. The major limitations currently facing this technique involve limited productivity and the toxic nature of solvents. The lack in functionality, the inability to easily manipulate resultant electrospun collagen is highlighted and potential mechanisms for the rectification of this, the application of functionalisation agents, discussed.

A parallel is drawn between the controlled application of functionalisation agents to that of additive manufacturing and coating techniques. Mention is made of the current developments, which combine these technologies and the limitation of these being the lack of retention in nano-scale resolution highlighted. The alternative use of a vapour based functionalising procedure is reviewed and the lack in control of these procedures is discussed with a potential solution of the combining of previously discussed 3D printing mechanisms implied.

Over the last year current literature has been reviewed, a hypothesis derived, fundamental testing conducted and a model for future work and research developed. The hypothesis relates to a process employing an advanced parallel electrode electrospinning technique utilising an actuated collecting surface and layered functionalisation approach to yield a complex collagen tissue. The fundamental testing highlighted a possible inability for a cavity or extrusion based collecting surface approach through the application of electrospinning fibre onto deformed surfaces. From this information the hypothesis was refined and a Computer Aided Design (CAD) model generated in Solidworks along with a costing generated for this.

The project will now progress to act upon these developments by constructing designed mechanisms to facilitate the testing of the hypothesis. Samples from these mechanisms will be analysed (structural, mechanical and optical analysis), resulting in an optimisation phase. Optimised mechanisms and the resultant samples will be subjected to thorough engineering and medical analysis yielding the potential for multiple publications.

Title

An investigation into the role of commercialization in the conservation of heritage buildings in Malaysia

Speaker

Alian Chan

Abstract

There are many heritage buildings in Malaysia that are worth conserving, but the process of conservation is both complex and costly. If the salvaged building can be used commercially then this may make conservation of heritage buildings more attractive. However, it is important that the essential heritage character is not lost when the building is turned into a commercial entity.

In this work, seven case studies of heritage buildings in Malaysia are examined in order to evaluate whether commercialization is compatible with conservation values. The data creates a framework for determining ways to preserve and conserve heritage building values during commercialization. This can be used by stakeholders (heritage building professionals, local authorities and community groups) to promote an increase in the conservation of Malaysia’s heritage buildings through commercialization.

Bio

Alian Chan is studying for a Master’s degree in Construction, majoring in Quantity Surveying. He has a Bachelor’s degree in Architectural Technology from UCSI University, Malaysia. He has 2 years of experience working in the Construction Industry in Malaysia as an architectural design consultant. He is currently working as an assistant architect with an Auckland-based architectural firm.

During his time working on the conservation of heritage sites in Malaysia he noticed a conflict on what to do with old buildings. On the one hand, the heritage council wanted the buildings restored purely for their heritage value – so many old buildings were simply abandoned. On the other hand, architects could restore heritage buildings for new commercial use.

Alian’s Master’s project will research the question of whether commercialization is a good solution to conserve and revitalize heritage buildings.

Whole Life Sustainability and Housing Refurbishment

Speaker

Dr Kenny Park

Abstract

The 2010 BRANZ House Condition Survey found that more than half of the 1.6 million existing homes (of which 1.04 million homes were built without insulation) were in poor or serious condition and the average cost of repairs and maintenance was over $9,000. Besides this, the housing sector in New Zealand (NZ) is faced with additional problems and challenges: increasing house prices, a huge housing-demand, compact jobsites, environmental degradation, import of materials, prolonged supply chains, lack of real-time information integration and labour shortages. New technologies are essential to examine the existing conditions of NZ’s housing and find a way to upgrade and modernise the NZ’s housing stock. One such technology is the proposed Housing Information Modelling (HIM), which models the flow of information for housing construction based on Building Information Modelling and seeks a way to integrate offsite technologies to improve the performance in the existing housing.

Title

Post-earthquake time and cost estimation model for commercial buildings

Speaker

Ravindu Kahandawa

Abstract

Due to the continuous earthquakes happening in New Zealand and around the world, more and more buildings are damaged. To make the decision on repair or demolition of a building by the owners, insurance providers and others, the economic viability of repairing is required. The cost models have been produced for this extend but most of them are probabilistic models yet not actual cost of damage repairs cost. This research tends to produce a quantitative model of post-earthquake building repair cost estimation model. Time estimation can be there after produced using bromilow’s cost-time model or work breakdowns.

Bio

Ravindu is a 1st yr PhD student under the supervision of Dr Domingo (Massey University), Dr Park (Massey University), and Dr Uma (GNS Science). Ravindu has 18 months of experience as a quantity surveyor in Sri Lanka.

Nurturing Capability and Nursing Vipers: reflections on 100-odd years of quality science

Speaker

Nigel Grigg

Abstract

We live in a world of high quality, reliable products and services, where quality has become more recognisable by its absence than by its presence. This does not happen by accident, as many organisations are still learning. Quality must be designed into a product or service, managed throughout the production and delivery system, and system performance tracked to enable on-going improvement. These are the domains of quality as theory and practice - its very ubiquitousness is the reason that almost all organisations in developed economies are managing quality, even if they might not always realise it.

Over the past 100-odd years, developments in quality science, coupled with a developing political/economic agenda emphasising deregulation, free trade and government non-intervention, have enabled some organisations to grow massively in scale and influence. With growing concerns about corporate ethics and environmental responsibility, the primary concern of quality science is arguably shifting from ‘doing things right’, to ‘doing right things’. In this talk I will reflect on nearly 30 years of involvement in quality, explore its key conceptualisations, and attempt to extrapolate possible directions for quality science in an age of complexity and globalisation. The presentation is mostly pictorial, with minimal text and no formulae.

Learning Theorem Proving over Large Formal Libraries

Speaker

Dr Josef Urban

Abstract

The talk will discuss several AI methods used to learn proving of conjectures over large formal mathematical corpora. This includes (i)machine-learning methods that learn from previous proofs how to suggest the most relevant lemmas for proving the next conjectures, (ii) methods that guide low-level proof-search algorithms based on previous proof traces, and (iii) methods that automatically invent suitable theorem-proving strategies on classes of problems. We will show examples of AI systems implementing positive feedback loops between induction and deduction, show the performance of the current methods over the Flyspeck, Isabelle, and Mizar libraries, and also mention emerging AI systems that combine statistical parsing of informal mathematics with such strong theorem proving methods.

Bio

Josef Urban is a researcher at the Czech Institute of Informatics, Robotics and Cybernetics (CIIRC) heading the ERC-funded project AI4REASON. His main interest is development of combined inductive and deductive AI methods over large formal (fully semantically specified) knowledge bases, such as large corpora of formally stated mathematical definitions, theorems and proofs. He received his PhD in Computers Science from the Charles University in Prague in 2004, and MSc in Mathematics at the same university in 1998. He worked as an assistant professor in Prague, and as a researcher at the University of Miami and Radboud University Nijmegen.

Seminar on the new Registered Master Builders’ Residential Building Contract RBC-1 2015

Speaker

Abstract

A client wanting to develop any construction project would enter into a construction contract with a contractor. Although this can be an oral contract, it should sensibly be done in writing. Construction contracts are typically entered into based on standard terms of contracts – of which there are a few within New Zealand and a great many more beyond New Zealand. Recently the Building Amendment Act 2013 was introduced to mandate certain types of residential construction contracts to be in writing. Being among the forerunner organizations within the construction industry, the Registered Master Builders Association embarked to amend their contract to make it compliant with the Building Amendment Act 2013. The outcome is the Registered Master Builders’ Residential Building Contract RBC-1 2015. We are privileged to have someone who knows the RBC-1 2015 very well to present and share his knowledge about the contract with us – Mr Tim Blake. Here is his brief biography and the topic he will be presenting:His presentation will primarily focus on the main residential building contract (RBC1-2015) used by Registered Master Builders. He will cover how the contract has had to be modified in response to the Building Amendment Act 2013 and the regulations passed under that Act. He will also discuss other building contracts and building guarantees used by Registered Master Builders.

Bio

Mr Tim Blake is the in-house legal counsel for the Registered Master Builders Association of New Zealand. He was admitted as a Barrister and Solicitor in 1991 and completed an LLM from Victoria University Wellington in 1992. Following that, he worked for over 20 years as a litigation lawyer. During this time he was also a law lecturer at the University of Waikato and at the Open Polytechnic.

Bacterial circuits of nitrous oxide production characterized using metabolic network modelling and metabolomics

Speaker

Dr Octavio Perez-Garcia, PhD Research Fellow, Department of Civil and Environmental Engineering, University of Auckland

Abstract

Metabolic network modelling and metabolomics are computational and analytical techniques used to characterize the flow of compounds and energy within metabolic pathways of microbes. This presentation will illustrate the application of such techniques to explain how different environmental conditions of biological nitrogen removal (BNR) processes trigger the production and emission of nitrous oxide (N2O) -a greenhouse gas and ozone depletion substance- by nitrifying and denitrifying microbes. The research approach will be exemplified with three analysis investigating the production of N2O in the following BNR systems: 1) nitrifying pure species cultures, 2) nitrifying mixed cultures, and 3) the denitrifying mixed cultures. Note: this presentation is part of SEAT environmental group internal seminar series and will be preceded by a presentation from research intern Emile Alaux on nitrous oxide emission by microalgae 1030, same location. Everyone is welcome to attend both presentations.

Industry experiences in product innovation and their relevance to university teaching

Speaker

Dr Mark Tunnicliffe

Abstract

In this presentation, case studies of product development undertaken at Tru-Test Limited, Auckland, are discussed, as well as the current Lean Product Development approach of the company. It is shown that the skills, tools and methods used in these projects and the current Tru-Test New Product Development philosophy correlate with the skills and proficiencies hoped to be developed using project-based and active learning in the redesigned SEAT BE course. Similarly, practices and processes used in these product developments relate to the content of the proposed papers in Innovation Management and New Product Development. For example, changing styles of project management of product development across projects are discussed, and these are related to Product Development practices and methods that may form content and case studies of these papers.
