Best Practices - A Model Solution

In an era of high technology and 3D renderings, you may think that physical models are old-fashioned and obsolete, but a new kind of model makes that anything but the case. 3D printed (3DP) models, modeling for the 21st century, are replacing the traditional cardboard and balsawood models, and making physical modeling even more important and relevant today than in years past.

3D printed models are created using a 3D solid CAD file and a three-dimensional printer. The printer works like an inkjet printer, but instead of placing layers of ink on paper, it lays down plaster in layers of about 4/1000 of an inch. The layering process continues until the model is complete. Models can be constructed in monochrome or full RGB color with a resolution of 600 dpi and can contain physical textures like roof tiles or images such as stonework. Any size or scale model can be made and any model can be integrated with topography and landscaping if needed.

The business advantages of 3DP models over traditional modeling are numerous. By automating the modeling process, 3DP models provide clients with time, labor, and cost savings over traditional modeling. Because a machine builds the model, the finished project is precise and professional looking, giving the best representation of your project possible. Many builders are using 3DP models as a sales tool to help sell spec projects, condos or to pass regulatory boards.

Physical models are an integral part of good communication during the design process. For architects, the cost and speed of the 3DP model process allows them to model multiple design ideas and do several iterations of the design to perfect all aspects of it before going to construction. Making multiple copies of a model is a cost-effective tool for designers trying to communicate across offices. For a client who is often not schooled in design and construction, a physical model eliminates the confusion they often experience trying to decipher blueprints or even 3D renderings. Actually being able to see and touch the structure provides them with instant understanding of the design.

To incorporate 3DP models into your design-build process, follow these basic tips:

Assess your software — While 3DP models can be crafted from any architectural input by using a proprietary conversion process, clients who use a 3D modeling programs like ArchiCAD or Revit are able to produce files that are nearly ready to print, allowing them to enjoy even greater cost and time savings.

Model only necessary elements. For example, most models are used to evaluate the exterior of a building. So, interior walls, floor plates and furniture are unnecessary.

Thicken elements of the model to insure successful printing. For example, a quarter inch pane of glass scaled to 1"=16’ would be much too thin to model. So, walls, windows, doors and roofs should be thickened so that to scale, they are at least 1/8" thick.

The largest single build possible is 10" x 14" x 8". Models that will be larger than this will simply be built in sections, and then assembled.

When submitting 2D plans, provide floor plans, rooflines, elevations, and site plans.
