Wayfinding - Research 2

Pinterest Board

In order to be able to all communicate the style which we would be further developing at a later date. The best way we thought to do this is through creating a group Pinterest board, meaning we could all contribute and also all take into consideration the design styles when creating initial ideas. 

In our first official meeting as a group, we discussed the brief and our interpretations of it. We shared ideas and delegated tasks and also planned how we were going to move forward as a group in terms of planning and structure.

Initial Ideas/First Meeting:

We had decided we would all gather some research on the brief and come back and present our findings to our group.

The main concepts we thought were strongest from the presentations were:

1. a mix of wall decals and 3d objects to give dimension to the system

• Once it’s there it’s there
• Mixture of wall and 3D element compliments each other
• Colours for each department

2. an adaptable system using interchangeable signage

• Adaptability is key, do it by block rather than letter, as its more accessible.
• Different sections and hook it on.
• Bars that are off the wall so they boards don't fall.
• Change of material between temporary and permanent modular plaques.

We decided on the adaptable system concept and began to plan a bit further into how we would undertake the task.

Further Ideas

• use a mix of materials to keep system looks interesting.
• metal (look at sustainability, durability, cost, processes etc.) and wood chip boards (cheap, sustainable as made from waste. Easily painted, cut etc.)
• laser cut some sections of the system (course name for example). Can use cut out letters as part of the system in another part of the building to reuse and reduce waste.
• consider scale and how it will be adjusted and changed throughout the building (in reception area individual courses/rooms etc may be presented smaller as in list form)
• present a physical prototype of our system in the presentation. Use offcuts of wood and metal (talk to wood and metal work). Present on A1 board to make a presentation stand out.

Planning

As a group we will be meeting every Wednesday to discuss our ideas and how we are moving forward with our own individual tasks and thoughts. In this way, we can ensure the project is being kept consistent across all aspects, and that all of us are on the same page. Adjustments to each member's ongoing work can be made here too to ensure consistency. We also have a shared Google Drive folder to share work and sync blog posts with each other.

Delegation

Hannah and Liam - visual research. Visual research entails existing systems and their uses, similar systems across Leeds

Callum - presentation. This entails the structure, layout and aesthetic of the visual presentation, alongside the scripting of it as well as further aids such as handouts, and physical prototypes.

Amy - materials research. Researching into sustainability, cost, durability etc.

Char (me) - initial design sketches and development. Coming up with initial designs for our chosen idea to be refined and developed in next weeks meeting.

Metal Research:

Our initial ideas saw us bring together a system that works using materials such as metal around the system. Before we could develop the ideas further we needed to gain an understanding of the materials that we would use. Lucky I have family links to who work in the metal manufacturing business and therefore gave me access to be able to ask questions about the properties of the metals we could use to be able to give us a better understanding of the ideas. 

The contact is a metal specialist at B.Masons in Birmingham.

Questions and Answers: 

What is the most sustainable and accessible metal?

Steel would be one answer because of its widespread use in a range of products and applications.  The majority of steel is collected an recycled (e.g. end-of-life body-in-white goods [such as washing machines, cookers, dishwashers and others domestic appliances] and end-of-life vehicles).  This type of steel is referred to as secondary steel as it is recovered and recycled.  Electricity is the main source of energy used to melt and process the material.  With various steel grades sorted, there is the minimum amount of additions made to produce a particular alloy type/grade.

Primary steel in comparison is produced from iron ore, coke and other additions (such as limestone) in a blast furnace.  This material undergoes various other processing stages and allotting additions to produce the desired alloy grade. This type of production route is energy and resource intensive. 

There are other types of metal, their abundance depends upon the amount of the metal element present in the ore or mineral mined.  The accessibility can be accounted for in the mining (e.g. open cast, deep mining) and extraction route used (the grinding and chemical extraction/refining methods). 

For most engineering applications, the metal is alloyed with other metals or elements to increase the mechanical strength and durability of the metal product. 

What is the cheapest metal?

The cheapest metal depends on the relative abundance of the element, the cost of the element on the trading market (such as the London Metal Exchange).  These trading markets control the market price based on factors such as availability and demand.  This does not fully account for countries which may control the amount of metal entering the market and directly influence the market price.  Certain countries who control the mining, extraction and refining of certain metals, designate these metals as strategic resources and control this commodity accordingly.  There are ethical considerations to be made, where certain metals are mined, extracted and refined in regions of the world designated as “conflict” areas.  The trading markets attempt to police and monitor which resources/metals enter the global market and ensure ethical trading occurs.

What is the most durable?

This depends upon the definition of durability (e.g. toughness, fatigue resistance, corrosion resistance, etc.).  Again, steel is the most durable as it can be easily alloyed to produce desired properties.  For example, the addition of chromium to steel to produce stainless steel (which the discovery was by a chance observation that this material did not tarnish or undergo significant corrosion).

It is possible to print onto metal?

Yes, it is possible to print onto metal but this depends on the chemical nature of the metal and subsequent surface preparation, cleanliness and chemical coating/treatment of the metal surface.  Certain metals are “noble” and make the use of chemical treatment to prepare the surface for printing (Noble metals have a full valence shell of electrons, which inhibits chemical reactions – such as oxidation, reduction and corrosion).

Steel (as with most metals) requires a surface treatment to remove any oxide or surface corrosion.  Once cleaned, the surface needs protection or priming to accept a coating or print onto the surface.  One effective way to print directly onto a metal surface is to produce a “mask” and then selectively remove areas for coating. 

Another way to print onto a prepared surface is by a dry film transfer.  The dry film can be heated to bond onto the surface. 

Any surface preparation (e.g. grit blasting or chemical etching) needs to clean (e.g. air blast, solvent rinsing and evaporation or water washing/rinsing and drying).  This would involve multiple steps, in which the waste by-products can be collected and sorted for reuse.   

What metal is best to cut and weld (or what could you do to a metal before doing these processes to make it most economical and accessible)?

There are several methods available to make precision cuts  – abrasive water jet cutting, laser cutting and wire discharge machining.  There are limitations to the thickness of sheet material that can be cut, but all methods benefit from using computer numerical control (CNC).  This allows a complex shape of the pattern to be programmed and cut into the sheet to produce any shape or template.  The water jet cutting would more environmentally friendly as the fluid can be recovered and recycled.  The advent of solid-state lasers allows high precision cutting of thin sheet material.  These laser types are more energy efficient compared with the gas laser systems.  Wire discharge machining uses an electrochemical bath and a wire electrode to cut, profile or shape.  The metal needs to be conductive as it forms the counter electrode.

Traditional cutting involves using a tool to cut the material (which is made from an alloyed steel of high hardness or hard carbide material with a CVD or PVD coating to improve cutting performance). 

Steel is the best to weld (but does involve surface preparation and cleanliness requirements to ensure good weld integrity).   Solid state lasers are being used as they can be precisely controlled and use significantly less gas and electricity in their operation.
