One of thetrends in 3D printing for 2017is the advance of materials science and the increasing range of 3D printable materials.
During his presentation at Formnext last year,3D printing industry analyst Terry Wohlershighlighted the expiration of patents around 3D printing with advanced engineering plastics, such as PEEK as an important area of development.
Costs cut from€1,000 to€100
Expiry of these patents means that, slowly, new 3D printers capable of working with these materials are arriving in the market. 3D Printing Industry reported that during this years CES eventShanghai 3D printing manufacturers Intamsys announced theirFunmat HT 3D打印机窥视. We’ve also looked atItalian company Roboze who can 3D print high-performance thermopolymers, including PEEK and ULTEM.
虽然新的3D打印机开雷电竞app下载始提供使用这些高级材料的能力，但原料的成本仍然令人难以置信。3D打印行业最近遇到了一家正在解决此问题的公司。3devo解释说，
购买PEEK颗粒只会使您每公斤100欧元，而不是花束阀芯，这会使您每座阀芯的收获1000欧元。
工业桌面式挤出机
3devo总部位于荷兰，是下一1.0工业桌面式挤出机的制造商，并声称他们可以：“用几乎任何东西制成细丝。”The 3Devo 3D printing filament extruder on display during Formnext certainly had a footprint that lived up to this claim.
该公司现在宣布了与PEEK测试下一个1.0工业桌面挤出机的结果。这项研究花了一年半的时间来进行和参与，“using 2 cleaning compounds as transition materials。”The company explain the process further,
从PLA切换到PEEK提出了一个独特的挑战：在高级电平挤出机内部建立温度，以窥视343度的高熔点。首先，我们使用第一个过渡材料缓慢地将温度从170度升至300度。温度越过300度，我们切换到第二个过渡材料，并致力于达到390度。
针对研究机构量身定制的3D打印丝
来自3devo网站显示机器可以在高达450℃的温度下运行，并且能够每小时处理0.7 kg。细丝可以在0.5毫米 - 3毫米范围内产生。制作较小量的定制3D打印丝的能力特别有吸引力。从与研究人员的对话并鉴于学术研究的经常秘密性质，人们希望能够在内部生产3D打印灯丝的能力。但是，当前的选项是有限的，机器需要更大的笨重。
3devo报告说：Working with PEEK has presented interesting challenges, chief among which involved extruding it in the correct temperature range, while factoring in internal pressure, and without affecting the material’s crystallinity. It has been a good start, and our first trials turned out to be easier than expected。”
The research looks promising and we understand the company are also looking at piezoelectric powders.
3月3日，devo将在RapidPro in Veldhoven, The Netherlands. 3D Printing Industry are looking forward to hearing more from the company, and would welcome the opportunity to spend some time testing the Next 1.0 Industrial Desktop Filament Extruder for ourselves.
Don’t forget,提名为第一届年度3D印刷行业奖开放.
