当印刷作业出错时，我们许多人都熟悉可怕的“意大利面”效果。启动GREENFILL3D, a spin-out firm of Polish 3D printing news providerCD3D, has now taken this quite literally with the development of a new sustainable 3D printing filament made from pasta waste.
丝状被称为Branfill3d，由小麦麸组组成，其生产，PASTA，PLA和其他几种可生物降解的成分留下的废物，据报道具有弹性和柔性特性。
For its debut, the filament has been used to 3D print proprietary advertising point of sale (POS) stands that will hold ready-made pasta in a rather fitting take on the circular economy concept.
无尽的意大利面
GreenFill3D的使命是将零浪费的想法实施到3D打印部门中，以在创建日常物品时创建新的环保标准。该初创企业希望通过处理与可生物降解或可回收成分结合的环保热塑性塑料，然后使用这些材料来打印各种产品。
Since July last year, GREENFILL3D has been working with on of Europe’s largest food producersMASPEX Groupas part of thePolish Agency for Enterprise Development’s (PARP) ScaleUp Program. The joint project saw the company focus on wheat bran, a waste product left over from the pasta production process carried out by one of MASPEX’s main brands,卢贝拉。
合作伙伴关系的目的是生产销售点（POS）广告台，该广告摊位由与其呈现的相同产品的再生浪费组成，以适应比例计划的零浪费和循环经济理想。
MASPEX GREENFILL3D废物原料小麦b提供ran which the company then sieved and dried until it was suitable for combining with other biodegradable ingredients and PLA. The material was then processed into a thin filament wire, Branfill3D, that could be used as 3D printing feedstock.
The material was then used to 3D print modular POS stands at GREENFILL3D’s print farm, which consists of more than 40 machines. The parts printed using Branfill3D were reportedly resilient and “to some extent” flexible depending on the wall thickness of particular components. According to GREENFILL3D, the fibrous structure of the wheat bran waste provided resilience to the 3D printed parts in addition to a smooth surface finish.
该公司的另一个相当利基的观察是，该材料在印刷过程中散发出烤面包的气味，显然在3D打印的零件上停留了一段时间。
The POS displays were made up of 20 percent Branfill3D filament, while its shelf connectors were made from PLA. In total, each stand consists of 34 elements that the firm claims are quick and easy to assemble together. The stands are then mounted on a pedestal made of 100 percent recyclable cardboard, to make each unit zero-waste.
3D打印的摊位被称为“ Ecopos”，将交付给选定的零售店“很快”，并将展示Lubella的现成的意大利面产品。
While the POS stands are the first demonstration of GREENFILL3D’s new Branfill3D filament, the firm says it is currently conducting tests for an automotive customer and plans to successfully deploy the material to other industries, too.
用食物垃圾打印
The circular economy is a concept that seeks to make optimum use of resources in order to avoid waste. Recent years have seen therise of various 3D printing-related initiativesaiming to develop closed-loop manufacturing processes to repurpose waste materials, particularly those from food-based sources.
一个这样的倡议是BARBARA项目，该项目在2020年底结束了四年的研究developing 3D printable materials from food wasteand agricultural by-products. The project, which produced 3D printed prototypes for the construction and automotive sectors, is now focusing on scaling up itswaste food bioeconomy 3D printing processesto a semi-industrial level.
重新利用食物浪费以添加生产工艺的其他示例包括用生物塑料代替基于石油的宠物雷电竞充值源自咖啡粉和橙皮, and converting food waste intobiodegradable PHAs。
More recently, an alternativewood substitute made from kombucha tea waste被授予去年的国家James Dyson Award, and is now seeking to leverage 3D printing to scale up production.
