In mid-July, Nishio Rent All Co., Ltd. hosted a construction 3D printer tour at its Tokyo Machinery Center. Over two days, 120 industry professionals, mainly from general contractors, attended, and we gave live printing demonstrations and explained how the technology can be put to use. Here's a look at how the event went.
Polyuse One introduced to tackle construction industry challenges such as labor shortages

According to Nishio Rent All, "Population decline and labor shortages are pressing issues for the construction industry, and customers often came to us for advice about them." As a way to solve these on-site challenges, the company introduced Polyuse One in November 2025.
The company now rents out Polyuse One for periods as short as a single day, and the machine has already been put to work at more than 20 sites and events such as tours.
120 attendees over two days, plus a printing demo of a gravity retaining wall
This tour, Nishio Rent All's first in eastern Japan, was held to raise awareness of 3D printers in the construction industry, out of a desire to "help people gain a deeper understanding of the actual technology and how it can be used."
On the day, Nishio Rent All first explained why it introduced the machine and the purpose of the tour, after which we presented an overview of the 3D printing construction method, the features of Polyuse One, and construction case studies.

This was followed by a demonstration of Polyuse One. Attendees watched a miniature gravity retaining wall and other items being printed, experiencing the printing precision and speed up close.
The printing on the day was operated by Nishio Rent All's own staff, who demonstrated firsthand one of the machine's key strengths: "it can be used and run smoothly even without specialist knowledge."
Attendees asked many questions, such as "How exactly does renting the machine work?" and "We'd like to know more about the strength and design of the printed objects," making it a great opportunity for them to deepen their knowledge of construction 3D printers.
A heartfelt thank-you to Nishio Rent All for planning and hosting the tour, and to everyone who attended!
Together with Nishio Rent All and all of our partner companies, we will continue to advance the technological development and real-world deployment of construction 3D printers to solve the challenges facing the construction industry.
