Jacobsen Architecture - Large scale residential take-apart model

Assembling multiple 3d prints of a house

This quarter scale, take-apart residential model was 3D printed from ArchiCAD geometry. The window details were laser cut from a white plastic for higher accuracy and resolution. The site was CNC machined on LGM's large mill from a high density foam.  The milled terrain was pocketed to accept the 3d printed building parts.

When planning for a large take-apart model there are a few challenges that are best addressed in the drafting stage to insure the highest quality output.  
The first is to understand and address the interior of the model.  Unlike smaller scale, exterior only, models, take-apart models must address the thickness and solidity of the interior walls and components.  Larger scale models can display smaller details, but many smaller scale architectural details, such as a faucet or cabinet hardware, need to be omitted.  Segregating non-printable items on particular layers during the drafting phase will save a great deal of time later in the process.  If some of the thinner components are important to the design, having a second "thicker" version on a "3d print only" layer will give you greater control over the final product.
The second is to think about the "cut lines" where the various components will be split.  This can be slightly more challenging and can be left to the LGM team if you do not have experience in laying out 3D Print volumes, but you can certainly call to discuss the process while you are drawing up the 3D model so that you can have complete control of the process.
