Passage 1(教材课文原文)

But the architects remain optimistic. The first few printed blocks are meant to be test pieces as they improve the process.
It takes about a week to print a 3-meter high block right now. The project’s leaders hope to eventually get that down to two hours and finish the first of 12 rooms in a year, and the entire house in less than 3 years.
Ultimately, 3D Print Canal House is an architectural research project, one that is very much being conducted in the public eye: you can actually buy tickets to visit the construction site for 2.50 Euros.

According to the passage, the 3D printer can type with plastic evenly. 1
