Bringing On-Site 3D Printing to Architecture

Through on-site 3D printing and generative design techniques our team helped the client save 40% on installation costs.

The Intro

Mancini recently completed the design and ground-up construction of the new Dolan Family Science, Technology, and Research Center at Chaminade High School in Mineola, New York. The design approach was focused on setting the stage for science and innovation, engaging students, faculty, staff and visitors at every turn.

Many people helped make this new facility a possibility, including hundreds of donors. Set against a striking vertical garden that climbs the full, three story height of the atrium is where a donor wall of transparent plaques featuring the names of the 945 donors that made this building possible is planned.

The Challenge

Large, clear acrylic panels are designed to be hung in front of a vertical garden to act as a mounting surface for lettering.  An initial thought was to use vinyl lettering, but it proved to be hard to read unless you were viewing the wall dead-on. We needed more depth.

So, the Mancini Design Lab team included 3D lettering as an option in the design and looked for a place to produce them.  Upon receipt of pricing from the signage vendors, it was evident that producing and installing the 3D letters from a third-party manufacturer was going to need a larger budget than we had to work with.  With just short of 1,000 donors containing anywhere from 15 to 25 characters a family, the number of characters needed for this install reached over 20,000 characters in total.  Typical 3D letters require ladders, glue and measuring stencils to properly install each character at the required spacing – we knew we could do better than this.

The Technology

To solve the manufacturing issue, the Mancini team utilized five 3D printers on site to prefabricate each character, which, through a customized script created by our in-house developers, are able to snap into place on the acrylic panels. Mancini underwent an iterative process that took dozens of attempts to finalize the perfect snap design. To ensure it was clear where each letter should be placed, each character has a unique configuration of pegs and corresponding holes for placement. With this design, there’s no way to put a character in the wrong place. All the installers have to do is just snap them in place. No ladders, no glue, no measuring tape!

To ease the labor costs and effort, the Mancini team created a layout that can be projected on each panel so that it’s easy to find the correct spot for each name–almost anyone could do it! This cost-cutting solution eliminated the need for industrial adhesives and/or expensive, off-site, specialized manufacturing.


This MicroFactory solution saved the school 40% on installation of the donor wall.  With less labor doing skilled tasks of hand gluing, climbing ladders and spacing letters the price went way down for installation.  Materials were delivered in raw form to 3D print, so there were less packaging and shipping costs associated.

The Wrap Up

Already well into their first year in the building, the school is still receiving donations and is still working with Mancini to make updates to the Donor Wall. The school plans to install the wall within the early portion of 2019.

3D printing represents a significant shift in manufacturing. By 2025, the market value of 3D printing is set to reach $25 billion. The Design Lab at Mancini is the proving ground for this technology and its applications within the built environment. Using design software like Grasshopper, the algorithmic modeling software for Rhino, Mancini designers can now produce a limitless range of generative design solutions.
