3D AFFORDABLE INNOVATIVE TECHNOLOGIES HOUSING PROJECT

Iowa State University College of Design Research Report 2022-24

00.Project Introduction

Introducing AIT Project Goals + Objectives

This project will help address an a ordable housing shortage with advanced technologies like 3D Construction Printing, which is happening now in a few select markets in the US — with claimed improvements of 2-3x faster construction, more reductions in labor costs, site waste and material usage.

Additionally, we are going to look at other technologies, some which you may already be familiar with. Like IKEA’s kitchen design website. We aim to advance this user-centered idea further — for the 3D A ordable Innovative Technologies (3D AIT) housing project.

Examples of these emerging technologies that we aim to integrate include Geographic and Geospatial Information Systems, building information & energy modeling, radar and lidar, onsite robotics, telepresence, virtual and extended reality, and advanced web standards for a digital project delivery solution. We will be applying these capabilities toward a demonstration project in Hamburg, IA with Brunow Construction.

This project is a comprehensive review of a 20th century legacy to a 21st century opportunity to transform a ordable housing. We do that with many Iowa partners and stakeholders — and would highlight Iowa Central Community College. This collaboration will look at ways these technologies can be developed into a new technical curriculum (both formally and informally) for workforce development - re-skilling, up-skilling and scaling this program across IA to advance a sustainable 21st century housing industry and to address the need for a ordable housing here in Iowa.

08.Cement 3d Printing & Modeling

Testing at Scale

The ISU Comptuation and Construction Lab is home to 4 Potterbot desktop scale printers. Over the past five years the lab has developed a series of scripts and wor lows for printing clay and is now applying this research to printing desktop scale cement mortar models to explore the possibilites of 3D printing concrete at full scale.

Scale Concrete Printing

This research began with a paper by colleagues in ISU Construction Engineerig department:

Kwangwoo Wi, Kejin Wang, Peter C. Taylor, Simon Laflamme, Sri Sritharan, Hantang Qin, Properties and microstructure of extrusion-based 3D printing mortar containing a highly flowable, rapid set grout,
