Experimenting with DaVinci

Posted on by

Mona Lisa (1)This Mona Lisa 3D print was made from a image that was applied to Standard Primitive Box object in 3D Studio Max this had a Displaced Modifier attached, the box has then had   increased segments to make the object appear more three dimensional.  This will turn the 2D black and white Jpeg Image into a 3D meshed object that can be printed later.

Mona Lisa (3) Mona Lisa (6)Using the black and white image of Mona Lisa we have done a number of controlled tests using a raster engrave setting on the laser machine.  Paper was used initially and then card and timber this has had a number of interesting results and is proving to be very effective if an image or graphic is need for a model or surface decoration for an object.

These experiments were carried out to demonstrate yet another potential use of the CAD driven machines in our workshop and could be applied to anything from facade detailing to micro site modelling.

 

First Year Starter Projects

Posted on by

Last week brought us an onslaught of eager first year students all keen to make their ideas into reality in the workshop. As many found, this wasn’t as straight forward as they might have thought! With projects like this it is crucial that things get moving quickly for avoid disappointment with machine bookings of workshop space as several students found last Friday.

This is an important lesson for future tasks as space in the workshop is at a premium and demand will be especially high in the last few days before submissions. The best way to prepare for this to the organised ahead of time and get to a stage where you can be making as early as possible in your unit.

For the students who did make it in there was a fantastic array of sketch models and concept models produced. As with all students, no matter what your experience within a workshop environment we encourage you to ask for assistance if unsure about your projects before starting. This allows us to advise the best construction methods and materials choice for your purpose and can help us free up space to get as many of your projects completed as possible. We look forward to see what comes our way next!

‘Extreme Conditions’ Predictive Contour Model

Posted on by

Stockport Contour Model (3)

This 3rd Year contour model of a site in Stockport has been made to demonstrate the effects of pollution in the area. Smoke, trapped in the lower box section of the model will escape through holes on the base of the site representing pollution from the area. The river area will eventually be flooded and show and overspill to the surrounding urban area.

Models of this kind are described as being ‘Predictive models’ in that they are attempting to show how a change may occur over time. The process of ‘flooding’ on this model will likely result in its destruction so it’s life will be short.

Stockport Contour Model (4) Stockport Contour Model (6) The group used laser cut MDF to build up the site contours and band saw cut MDF for the site roadway. The buildings were made from Jelutong wood blocks and the base box from band saw cut acrylic with acrylic square section.

Garden Pavilions Continued – Learning Curves and Problem Solving

Posted on by

Development of the 6th year pavilion projects is continuing at pace down in the workshop. Test models often bring assembly issues to the surface which Alexander Valakh, Lorena Chan and Nancy Chan have been finding with their concepts. This is exactly why these models play a vital role in design development.  Here Alex has created his outer skin from laser cut polypropylene plastic sheet fixed with pop rivets. This has proved tricky and mid way through assembly it became clear that a more uniform stapled fixing would have been more effective. Lorena and Nancy have spent the last few days fixing components for this concept together. The original concept was to have a smooth curved structure forming the tunnel walkway. As the components were fixed the group found that the curve was un-uniform due to the varying strain between components. Whilst this isn’t exactly how the concept was drawn it has still proved an interesting experiment and may still be taken to the next stage.

Pavilion Project (4)The concrete cast (below) has also had some teething problems with the cast numbers not turning out as refined as the group would have liked. This process will require more thought if it is to be taken forward. The group has found that their choice of aggregate or quantity used may be to blame for the irregular casting around the number details. One thing is for sure it wont be going too far given its weight despite having a polystyrene block inside to reduce the material used!

Garden Pavilions at Dunham Massey 2013

Posted on by

Much like the brief set this time last year students are currently in the concept stages of designing a series of pavilions to be constructed at 1:1 at Dunahm Massey (Read our blog post here). This project was challenging for both staff and students last year and really pushed the boundaries of what the workshops can handle.

This year the project is aiming to be more refined and, with support of workshop staff, come to an effective and ‘speed-bump’ free conclusion!

Alexander Valakh (Below) is working on several sketch models to help convey his project named ‘The Shadow of War’ to tutors in the hope it will be taken to the next stage of development.

To test his theory for eventual 1:1 construction Alex had produced a plywood sketch model in identical fashion to the full size proposal on our CNC. Producing this model has allowed Alex to explore problems he may encounter whilst using this method and has already identified several areas that will need more thought. These issues are not a hindrance to the design process but feed into it and shouldn’t be seen as a waste of time. problem solving through trial and error models are often the best way of refining a design for production.

This group is also producing another concept pavilion using paper to create the sketch model. The flower-like components are created and joined using pop rivets which will eventually form a curved canopy. 

Another (!) concept from the same group involves casting concrete blocks as part of a wall sculpture. This is part of the same brief but is less interactive due to the nature of the proposed site. This was poured yesterday afternoon and is still setting so we’ll hopefully have some more pictures of how that is progressing by the end of the week.

 

Kinetic Sculptures

Posted on by

Over the last two weeks groups of 3rd year students have been in the workshop producing work under the brief ‘kinetic sculpture’. This broad brief allows them to interpret the idea of movement in construction and helps to prepare them for later units which will ask them to explore adaptable buildings – highly likely to feature moving components.

We will post more on this unit as it develops!

Plaster Casting guide inspired by Timothy Richards Models

Posted on by

Earlier this year myself and Jim went on a visit to Timothy Richards workshop in Bath. Read more about that visit here.

In response to what we saw there we decided to have a go at casting some facade tests of our own to demonstrate to you the potential when using this method for modelmaking. Starting with some reference images of the University of Manchester Archway we decided to focus on one of the Gothic style windows as our subject.

Making a ‘Master’

Initially recreating the form of this stone work in miniature may seem time consuming but as you will see the end results are fantastic and the intricate detail featured is easily replicated by casting.

A good way of creating details like this is by layering sheet material, in this case acrylic. Planning the layers on CAD will allow you to break down the details into manageable  stages (Above). When combined, the layers of laser cut acrylic form the recesses and steps in the winder with the radius in the stone work being replicated using a filler and hand sanding (Below).

Spraying a coat of primer paint on hand finished areas can help to identify any imperfections in the surface (Below). This primer can then be sanded back

The extra details of the window can be formed using styrene and or abs strip with any further radius being creating again with filler. Once complete the master model is ready to be moulded. 

 Pouring a Silicone Mould 

The are a wide range of silicone’s available for mould making so it is always advisable to check the specification of individual products before committing to use them on your master model. Firstly ensure the master is secured to a mould former – in this case we used a storage try which suited but bespoke formers are usually required.

Ensure the silicone is mixed to the manufacturers instructions and pour in a thin stream to avoid any air bubbles forming against the master mould. Ensure the master is sufficiently covered and allow to cure for the recommended time.

Once cured carefully remove the silicone mould preserving the master mould to be reused if any problems occur. The benefit of using silicone is that the flex allows the master and eventually cast items to be easily removed without much stain on the items themselves.  Some minor trimming of silicone overlap may be required before the mould is ready to be used for plaster casting.Plaster Casting

As with the silicone there are many types of plaster available so always check to see if the specification suits your needs. In this case we simply used stone plaster mixed to the correct consistency and poured directly into the silicone mould – no release agent required.

Once the plaster has set it can be carefully removed from the mould giving a completed cast. These sections can be used as tests or replicated to create a more detailed facade. 

One area we have touched on is adding pigments to the plaster mix to give varied results in terms of finished cast colouring. We will revisit this area when we have time to experiment some more and let you know how it goes. If you have any ideas that could make use of this method of making be sure to get in touch either via email or in person at the workshop. We are more than happy to help! Scott & Jim

 

 

Welcome back to ‘SEED’ and a new academic year!

Posted on by

As some of you may have noticed we have added an extra ‘E’ to our name due to the merge with the School of Education. Our full name is now the School of Environment, Education and Development or SEED.

Busy summer

Over the summer we have been busy co-writing a second edition to the highly acclaimed book ‘Architectural Modelmaking’ by Nick Dunn. We expect the book to be published sometime next year and should prove very useful for existing and new students of architecture. We’ll post more on this when we can!

This had kept us productive along with a materials re-stock and clear out in preparation for your return. We hope to stock some new acrylic thicknesses in the next few weeks. Up to date materials price lists are now up in the workshop and can also be checked here on the blog.

Up-front payment for laser cutting

From now on we will only be allowing students to book laser cutting slots if they have paid. This change is being implemented to reduce the number of no-shows that occurs during busy periods which led to many hours cutting time being wasted last term.

New Full-Time Workshop Technician 

The workshop now has an additional member of staff as Scott Miller has now been made a full-time member of the technical team. Some of you may have met Scott last year when he worked with us on a casual basis. Scott is a very accomplished model maker and will be happy to help with any of your model making requirements.

The Arts University Bournemouth: Workshops & End of Year Show 2013

Posted on by

Following our trip to Bath and Timothy Richards’s workshop we drove down to Bournemouth for a private workshop tour and a look at their end of year show. Having studied in Bournemouth for my degree I was already aware of what they have but felt showing Jim the facilities first hand would be of great befit to the constant refinement of our own workshop. Unlike our workshop at SED, the Bournemouth workshops cater for a wide range of courses and as a result are set over two large floors.

One aspect of the workshop design that would be great to incorporate into our own is the segregation of certain areas. This is a difficult task in SED due to our restricted space however certain changes are possible and some solutions could come from other institutions such as this. Of particular interest to reduce the amount of dust in the air we breathe we were interested to look at the sanding benches (below). These were in a purpose built room with enclosed extraction to reduce the spread of dust. Whilst we are limited in space, incorporating one of these benches into our workshop may be a possibility and we will consider implementing it within the next year.

Another separate department is the CAD-CAM area which incorporates all CAD driven machinery away from the main woodwork shop space. As with the sanding room, it is unlikely we will be able to create such a space without expanding the workshop. This said, by simply arranging the machinery together and the materials they use effectively it is clear that this side of the AUB set up works very well. We will be making efforts to improve on material storage and availability over the summer.

One of the main draws for me to study in Bournemouth was the ability to collaborate with so many different courses. The AUB has facilities to cover Architecture, Interior Architecture, Animation, Costume Design, Model making, Make-up, Graphic Design, Film Studies, Photography and many more Arts based courses. Here are a few shots of our look at the End of Year show across the campus.
