Made using an MDF mold this detail model aimed to demonstrate the window detail Becky was focussing on at her site. The mold proved to be the most time consuming aspect of the model but turned out successfully. It is always worth spending longer on mold design to ensure a good cast.
The mold was made using MDF which can absorb moisture from the plaster mix and therefore needs to be well sealed before pouring. Becky used Vaselene to act as barrier and release agent for the cast.
The internal void was made by using blue foam to allow for contracting of the cast as it cured and then be removed. This too was well coated in Vaselene to aid removal.
Once cured the MDF was unscrewed and removed before cutting out the internal blue foam. Additional window details were added using initially laser cut and then modified components.
Lauren and Becky decided to create their site master plan using 3D powder printed components on a laser cut plywood base. The completed model looks great and shows in detail all the shapes that make up the exiting structures their chosen site.
For those eager to try 3D printing it may be worth noting that this is a fairly unorthodox approach to making a site model due to the cost implications. This batch of printing came to a total cost of £116. When combined with other material and machine use time the total cost of the model came to around £150. This is minimal compared to commercial model costs but cheaper approaches can be carried out if cost is a concern.Despite these cost implications, the outcome is very successful and clearly conveys the level of detail sought for the project. The use of timber against black acrylic to represent waterways is a style often used by David Chipperfield Architects Models.
