New Typologies for Brexit Britain

The New Typologies exhibition at Architecture Fringe 2017 in Glasgow occurs in the political maelstrom that is Brexit. The exhibition opens just weeks after the General Election where the promoters and "owners" of Brexit took a hammering and opened up the question, "What kind of Brexit does the country want? What kind of country do we want to live in?" 

New Typologies asks what kind of buildings do we want to reflect this nervous new world. 



McGinley Bell's Health Centre with the corporate scale of a bank or power company headquarters cut through with monumental openings. An airy castle of health and not much in the way of grovelling in the gutter of austerity.




The school building by Stallan Brand amounts to a complete redesign of the learning process. The school reflects the needs of learning in the digital age where interpretation and questioning of data is the challenge that education needs to address. The rampant model presented in the exhibition suggests rather than represents a solution, an open venue of exploration and discovery. 




Adam Nathaniel Furman's Town Hall recognises the rise of the city as a political force that can and will make a difference in people's lives. His bold and colourful design is a reworking of the elements of a traditional Victorian town hall, moving away from the bland managerial local politics of today. Both a move back to the liberal mayors that "spearheaded reforms, and massive urban improvements that transformed the lives of those living in the new metropolises." and a move forward to a building, a Democratic Monument, used and owned equally by both elected officials and the people.



"In crisis lies the greatest opportunity for reinvention." says Furman. These are important explorations at a critical point in time. Brexit, wanted or not, offers an opportunity to reassess - everything. Possibly we might even imagine a world where there is more to public life than cost cutting.

Increasing productivity or part of the problem?

A couple of things happened recently that made me think differently about public perception of 3D printing. 

Firstly my mum recently visited our workshop with one of my nephews. My mum repeatedly referred to our 3D printers as robots, mainly because my nephew is at an age where he is fascinated by robots and all things mechanical.

The other occasion was in a throwaway conversation with our neighbour. I was banging on about driverless cars and AI imminently taking everyone's jobs. He turned to me and called me a hypocrite, I run 3D printers which are taking away other people's jobs right?

Then during a third conversation with a surveyor who had asked us to print a hole in the ground, yes he really wanted a print of a hole in the ground! Why did he want a colour 3D print of a hole in the ground? He was trying to persuade older contractors of the value of capturing 3D data. Often they just will not wait even to take a series of photographs from which a virtual model can be created to record complex underground servicing. 

From the mess of servicing underground you would think it would be a good idea to record and share this information. It is not a difficult idea to grasp but I can see how it could be a difficult idea to implement.

Putting all of that together, 3D printing of architectural design models is the staple of our business. The thing is that until 10 years ago it was really not possible to 3D print design models. 3D printers were around before that but price and speed where not right for making what are essentially concept models. 

So for most architects they became design professionals without needing 3D printing to make design models. And the truth is that like recording that underground servicing it has not been easy to introduce 3D printing into most architect's design workflow. 

This is not to say that architects have never used models and with the rise of 3D printing some have tried to apply 3D printing to their existing requirement for physical models - which is often for high quality presentation models. But that is not what 3D printing is good at unless a modelmaker is involved in transforming the 3D print into a convincing model.

A presentation model does not serve the same purpose as a design model. A design model helps stakeholders make decisions during the design process and presentation models sell the final design. 

In this sense, 3D printing design models is an attempt to add value to the design process. If we are replacing anything, it is the time consuming card and foam models which were traditionally made by architectural assistants. Often made over the course of a night, fueled by pizza and coffee. Architectural assistants do not become architectural assistants to stay up at night making card mockups, they do so to become architects. So are 3D printers taking jobs in this instance?

There is a real threat to jobs in large established industries from AI and robotics. Capturing 3D data on building sites and in road excavations or helping stakeholders make clear decisions in the design process is not a threat to jobs. Instead these are processes for adding value and increasing productivity of existing jobs.

Public perception of 3D printing is formed not by reality but by manufacturers hype and the imaginations of the media. 

Finally, is a 3D printer a robot? Robots do do boring repetitive tasks when they have time off from taking over the world I guess.

The gig economy - a missed opportunity

The term gig economy is often not what it says it is and this is usually bad for everyone except employers (except of course that they claim not to be employers). 

20 years ago I spent 3 years working in the gig economy as a self employed cycle courier. What this meant was working for a courier company with all of the usual employees, sales people, call assistants, controllers, managers but no couriers. All of the couriers; van drivers, motorcyclists and pushbikers were self employed.


At the time I didn't mind this, in fact I enjoyed the freedom and taking responsibility for looking after my own affairs was a positive experience. However the system was and remains inherently inefficient and the opportunity to make a living was limited.


20 years later I find myself in a position where I use couriers on a daily basis and being a somewhat impatient person I am frankly skeptical about the benefits of the so called gig economy.


What exactly is the gig here? Is it the individual job or is it the days work? Or the weeks work? Or the month or year? The way this work is renumerated is by the job.  The reality is that each courier is in service (employed) to a single courier company. As self employed couriers they should be free to take jobs from any courier company based on location and where they are headed. 


This would effectively widen the pool of couriers available from those in service to a particular company to the entire fleet of self employed couriers working at any one time. In other words creating a real market for self employed couriers to compete in.


Increasing the efficiency of the overall system in this way would mean a better service for customers, increased productivity of the couriers and improved services offered by courier companies.


How can a proper market for the services of self employed couriers come about? Can a GPS network based technology be applied to create such a market where courier companies hire riders and drivers based on their location, direction and availability? 

A system like this could increase productivity for everyone concerned including the businesses who need to use these services.

While writing this I came across a company called Brisqq who are supplying retail customers with deliveries. They say that "Brisqq's algorithm selects the best freelance courier (closest, highest rated, most appropriate vehicle etc.)"

Brisqq's reference to freelance couriers suggests they really are plugging into a pool of freelance couriers. I wonder if this is what they mean or is this their freelance couriers who are not allowed to work for anyone else? I hope its the former.

Cyberbond for 3D printing

I am a loyal Cyberbond customer. I have used their cyanoacrylate to finish 3D printed parts for more than 10 years now. The only reason I would change is if I found a product that would produce a better finish.

The fact is Cyberbond make a high quality product. Here is what I mean.

The test parts shown below were made in 2009 and 2010 respectively. They have been kept out of sunlight since that time and discolouration is minimal.

Sample parts in 2009 and 2010 
shown along side a part made in 2017

This ability to keep colour is not the same with some other products. If you leave Cyberbond to go off in the bottle it remains completely clear. No discolouration as it ages. I have had samples of inferior product go yellow in weeks.

When I visit customers I want to see design models crowding their offices that look good. Models need to stay good for the life of a project which could easily be 5 or 10 years.

This is not a promise that our parts will never discolour. Direct sunlight, moisture and dust will all discolour 3D printed parts made on ZCorp or Projet x60 machines. 

In addition to not discolouring, when choosing cyanoacrylate for this purpose you need to look at other physical characteristics of the glue. If the glue is too thin it will leave a white powdery look to the model. Too thick it will produce an uneven finish with matt and shiny streaks. 

All in all, sales people are not going to fare well armed with their "very competitive price" and claiming to "supply all the major users in the UK and Europe". Well, I am sorry but you are not supplying this one.

Why I voted for 3DPRINTUK

3D Printing Industry "The Authority on 3D Printing" are organising their industry awards and entreating readers to vote...

In the 3D Printing Bureau section there are two manufacturers, a portal and Shapeways offered as service bureaus that you might choose from.

I am not impressed.

I could list a whole bunch of bureaus that I consider our direct competition and all of them are better bureaus than anything this list offers.

My hastily compiled list would consist mostly of small bureaus providing professional services. The most important word there is service and this is the one attribute I would not ascribe to 3D Printing Industry's nominated bureaus.

Stratasys and 3D Systems both offer lumbering bureaus that can only compete with bureaus offering a decent service because they don't have to pay exorbitant costs of machines and consumables. If you are not a sizeable corporate they really are not going to be interested.

3D Hubs is not a bureau. 

While Shapeways has done much to offer a diverse range of 3D printing technologies at low cost,it is entirely consumer focused and offers little in the way of professional services. 

Good service bureaus create relationships with customers. They help them to prepare data, they advise on the best technologies and materials, they usually advise on how to produce parts at lower costs and they print and finish high quality parts and they do all this quickly and efficiently. 

I voted for 3DPRINTUK because they are a better 3D printing bureau than any of the other options on offer.

Yet another 3D printing App!

Oh gosh another app to connect engineers and designers with 3D printing bureaus. Still peddling the 3D printing hype, now with a rambling message conflating additive manufacturing and rapid prototyping and all projected into a dreamy future.
Allegedly engineers do not know if their parts are printable. They need an app to check their parts, to fix them and then to tell them what material to use and who should print it.
In these days, before AI finally saves us from our own innate idiocy, it is usually best not to expect help from an app. If engineers really need help then it is best to speak to real people with real experience. Automated file fixing procedures are very unreliable and can lead to all manner of unfortunates being printed.
Not only can people advise on printability and appropriateness of materials they can also advise on how to optimise files for cost. An app will not turn around and suggest you hollow the part, make it in parts, nest parts or simply reorient the part to reduce costs. It would be very easy to pay over the odds through an app.
Phone around some bureaus, ask the usual questions. Will this work? Is there a better way to do it? Is there a way to do this for less? Bureaus are in business to build trusting relationships with their customers and to build their reputation generally. Apps have nothing at stake on each job they process except the percentage they take.
Apps are seductive. They give the impression that everything is going to be easy, everything has been thought through. Its pure snake oil.
