Wehad anticipated它几个月前，但是现在，B-pet的100％完全回收的细丝是商业上可用的现实and the Argentinian startup behind it does not intend to stop there. This means that the full injection-molded-transparent-plastic-bottle to 3D-printed-transparent-plastic-bottle-cycle is now a real opportunity for the 3D printing industry as a whole, with many more interesting initiatives to come along soon, including many related to SLS technology.
PET(PolyEthylene Terephthalate)is one of the most widely used thermoplastics there is. It is used to make plastic drink bottles as well as many other products (including fabrics) and for packaging purposes, because of its vapour barrier and strength properties. It is一种相当僵硬且非常轻巧的材料，使其非常强大且具有耐电性。也是stable, non-toxic and, in its original state, colorless and crystal clear.
尽管首次使用宠物（剪裁宠物纸上的废物）可以用来挤出细丝，但回收第二使用宠物并不容易，因为它倾向于吸收与之接触的材料（饮料或食物），从而改变其特性和外观。通过研发，B-PET改善了用于3D打印的废物回收过程。公司的REcycled Pet具有与Virgin Pet相同的特性，但成本降低了70％。它甚至提供了改进的特征，包括柔性强度和易于粘附等特殊功能。当挤出以产生灯丝时，它的直径一致，不会形成气泡。
B-Pet has big plans for its PET recycling capabilities. The filament is already available in transparent, white, black and blue (currently out of stock) colors, selling for $30.00 a spool. According to the current roadmap, B-PET will launch a recycled PET-based powder for laser sintering processes in 2015 and has even made plans to launch their own SLS 3D printer by 2016. Then the P2P (PET to PET) cycle can truly be complete.
