國(guó)內(nèi)首座3D打印橋年內(nèi)在上海投入使用

By the end of the year, a 3D-printed bridge will be put to use in China for the first time.

我國(guó)一條3D打印橋梁將在年底首次投入使用。

Different from traditional bridges, its novel design doesn't use reinforced concrete.

與傳統(tǒng)橋梁不同，這座創(chuàng)新性設(shè)計(jì)的3D橋梁沒(méi)有使用鋼筋混凝土。

It is made of resin designed to weather rain and sun for an extended period, and that's durable enough to meet national construction industry standards.

它是由樹(shù)脂制成，能承受長(zhǎng)期的日曬雨淋，其耐久性足以滿足國(guó)家建筑行業(yè)的標(biāo)準(zhǔn)。

If parts of the bridge become damaged, they can be repaired separately.

如果橋梁的某些部分損壞了，可以單獨(dú)進(jìn)行修理。

The 15-meter-long footbridge in Shanghai will take 35 days to build, and will have service life of up to 30 years, according to its chief architect.

據(jù)總建筑師介紹，這座位于上海的15米長(zhǎng)的人行橋共耗時(shí)35天來(lái)建造，使用壽命可長(zhǎng)達(dá)30年。

The complex curved surfaces of the bridge can only be achieved using 3D printing technology. Based on laboratory testing, it can bear a load of 250 kilograms per square meter.

橋梁的復(fù)雜曲面只能通過(guò)3D打印技術(shù)來(lái)實(shí)現(xiàn)。經(jīng)實(shí)驗(yàn)室檢測(cè)，該橋每平方米可以荷載250公斤。

This isn't the first time that a 3D-printed bridge had been made in China.

其實(shí)制作一座3D技術(shù)打印橋在我國(guó)并非首例。

In July last year, Tongji University in Shanghai made the world's first two 3D-printedpedestrian bridges. But that pair of bridges was only build as a demonstration, and not for actual use.

去年7月，上海同濟(jì)大學(xué)內(nèi)就有全球第一組3D打印完成的步行橋。但當(dāng)時(shí)那兩座橋只用于展示，不能實(shí)際使用。
