I recently wrote an article that was featured on the blog 3D Printing in AEC. Check out the full post below or by clicking here for the article on 3D Printing in AEC.
As three-dimensional printing (3DP) technology increasingly embeds itself within the architectural practice as a viable representational technique, architects and designers must reconnoiter around the ideas and strategies that initially spawned the technology. Whereas 3DP’s current influence on the architectural design scene seems to be most characterized by the production of monolithic, mono-material, massing components, its success and influence originated on the engineering platform via the ability to produce accurate, complex geometrical prototypical, full-scale components.
Most significant to the architectural designer in the articulation of a physical study model is the ability to produce artifacts that facilitate and direct to the iterative design process. A primary catalyst for the success of this process requires dexterity and efficiency in the fabrication process itself. As designs are quickly modified and manipulated to fulfill evolving design intent, the fabrication process must efficiently anticipate and transform to accurately articulate new design ideals.
By deploying a scale shift likened to the prototypical roots of 3DP technology, the images below document a series of full-scale design studies investigating terracotta rainscreen cladding profiles. Of primary importance to the design team was the ability for the models to clearly convey the legibility of the profile from various distances and perspectives. Secondarily, the models proved useful in the comprehension of lighting consequences between the profiles. The combined curvilinear and faceted nature of the profiles clearly emphasizes the necessity of the digital fabrication process. Most importantly, the full-size scale of the models in conjunction with the limited scope of the investigation allow the fabrication process to efficiently inform the decision making process. Two-dimensional, digitally documented profiles were easily and quickly manipulated to generate simple digital extrusions, thereby keeping pace with design changes.
Scale is here at the crux of the success; clients and designers alike are drawn to and impressed by the resolution and mastered comprehension of a seemingly insignificant aspect of the design, articulated in a clear and beautiful way.

This Earth Week, we’ll be covering five landmark buildings exemplifying new approaches to building performance and sustainability.
The Beth Israel Deaconess Medical Center Klarman Building is the first hospital in the northeast to implement chilled beams in an inpatient setting. Early energy analysis demonstrated that the use of chilled beams would be the best way to reduce building energy use.
For this strategy to work, however, the peak thermal loads of the façades could not exceed the capacity of the chilled beams. An integrated design approach and in-house modeling allowed for constant tuning of the façade to optimize glazing, solar exposure and massing. The building orients glazing to face true north and south to minimize heat gain and maximize occupant comfort, resulting in a 15% reduction in peak solar load.
Beyond performance, the distinctive serrated terracotta façade reflects the scale and cadence of individual patient rooms, providing a delicate scale and texture to the façade.
