Over the past few years, designers and construction companies have experimented with using large, 3D printers to build homes, offices and other structures.

  • The old thing: "Printing" building blocks and parts of homes, which are then assembled on-site.
  • The new thing: Using 3D printers to print an entire building on site.

Pros: 3D printing would help eliminate waste in construction and can use recycled materials as building materials. Homes eventually could be easily personalized, and could provide cheap, safe housing in the wake of natural disasters.

Cons: There's still a long way to go with 3D technology and building printers that are large enough to build these structures. It's difficult to meet the intricacies of building code requirements while programming the printers, and most homes that have been built are tiny and not particularly stylish.

Here are some of the most recent 3D, livable space projects.

1. Houston, Texas: Alex Le Roux designed and built a concrete 3D printer while at Baylor University in June of 2016. He then oversaw the first livable home created entirely by a 3D printer in the U.S. The "house" is 8 feet by 5 feet by 7 feet.

2. Austin, Texas: the American construction company Sunconomy, along with Apis Cotr — based in San Francisco and Russia — are raising money to build affordable, 3D-printed housing — one house will be given to a disabled veteran.

3. Russia: Apis Cotr built a 3-D printed home in March. The home is 400-square-feet, took less than 24 hours to build and cost just more than $10,000.

4. Massa Lombarda, Italy: WASP set out to build the first 3D printed village — the village of Shamballa. Construction began last year, and the first house only cost 48 euros.

5. China: A 400-square meter, two-story villa was printed in 45 days on site by HuaShang Tengda last year. The structure was tested and could withstand a level 8 earthquake.

6. Amsterdam, Netherlands: DUS Architects constructed the 8-square meter Urban Cabin last year as part of its 3D Canal House project, which will ultimately include 13 3D-printed rooms.

New Zealand Prime Minister Jacinda Ardern said it's too early to say whether next month's elections will be postponed after she announced Tuesday four people had tested positive for COVID-19 after no local cases for 102 days.

Zoom in: NZ's most populous city, Auckland, has gone on lockdown for 72 hours and the rest of the country is under lesser restrictions.

Primary elections are being held on Tuesday in Minnesota, Georgia, Connecticut, Vermont and Wisconsin.

The big picture: Georgia and Wisconsin both struggled to hold primaries during the coronavirus pandemic, but are doing so again — testing their voting systems ahead of the general election. Rep. Ilhan Omar (D-Minn.) is facing a strong challenger as she fights for her political career. In Georgia, a Republican primary runoff pits a QAnon supporter against a hardline conservative.
