渝粤搜题

"The printer did not always manage to spread the plastic evenly, making some of the ribs of the honeycomb structure of the block uneven," reported ARN?(Australian Radio Network)?to the surprise of no one who has used a 3D printer. But the architects remain optimistic. The first few printed blocks are meant to be test pieces as they improve the process.渝粤搜题

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.渝粤题库

国家开放大学作业答案

The top floors will become more ornate, for example, as newer techniques are incorporated. They'll explore the possibilities of 3D printing, like the honeycomb walls or an entire room recycled, redesigned, and built anew. Nobody's going to move into a 3D printed house soon, but, if anyone ever does, something might be learned from this experiment by the canal.

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