今天启动的3D打印行业指数是我们扩展的最新成员添加剂制造业的分析工具和数据库套件.
每个季度，3D打印行业指数将被编译和发布。该指数是使用3D印刷行业的主要企业的调查来构建的。从行业领导者的角度来看，这是关于过去，现在和将来对几个关键指标的一种衡量标准。
在接下来的几个月中，我们在6月30日末的调查结果将与未来季度结束日期相应的数据点加入。这将允许对3D印刷行业的趋势进行分析。
什么是情感索引？
Sentiment indexes are powerful and widely used macro-economic tools. Central bankers, economists, financial analysts, VCs, investors, financial managers and journalists use them for forecasting, trend analysis and generally to gain insights.
众所周知的索引包括IFO商业气候指数,GFK消费者气候指数,密歇根州消费者情绪，和会议委员会消费者信心指数.
我们使用3D打印行业指数的方法相似。
The data for our index is collected by surveying a representative sample of the additive manufacturing ecosystem on a quarterly basis.
As a global industry, enterprises from across the world are represented. These range from operations with fewer than 10 employees to much larger enterprises. Hardware manufacturers, 3D printing material producers, 3D scanning companies, resellers, bureaus and the other enterprises that comprise the 3D printing industry are all represented.
这个小组将necessa复查并更新ry to ensure the Index is a valid representation of the industry.
我们将为读者提供3D打印行业指数的亮点和见解。参加小组调查的公司将可以访问更广泛的数据集。
3D打印行业指数的方法论
The 3D Printing Industry Index is based upon the responses to a 5 question survey.
The questions address trading activity for the past and coming quarter, past and future hiring plans and changes to the gross margin. The full questions are as follows.
1. How was trading activity at your company during the past 3 months?
2. How do you expect trading activity to be during the coming 3 months?
3. Has your company expanded its 3D printing workforce in the last 3 months?
4. Does your company intend to expand its 3D printing workforce in the next 3 months?
5.您期望在未来3个月内毛利率变化？
索引，全球，现在和未来有3个部分。
从对调查的响应中，指数的计算如下。
Global Index: S = (n+ – n-)/(n+ + n- + no)
n+正答案的数量，n-负答案的数量和n0中性答案的数量。
我们还计算了从问题1和3的答案计算的当前索引，以及未来的3DPI情感索引从问题2、4和5的答案。
The resulting value of the Index will range between -1 and 1. A negative figure indicates that a majority of the panelists are pessimistic. While a positive value indicates that a majority of the panelists are optimistic. The closer the value is to 1 indicates just how positive sentiment is among the panelists.
我们打算在7月，1月，1月和4月发布3D印刷行业情感指数季刊。一旦收集了几个季度的数据，就可以进行趋势分析。
2018年6月3D印刷行业情感指数的结果
For the quarter ending the 30th of June 2018, the Global 3D Printing Industry Sentiment Index is 0.70. This value indicates a strong optimism among the panelists.
The value for the Present 3D Printing Industry Sentiment Index stands at 0.76. This demonstrates a healthy state for our sector. The Future 3D Printing Industry Sentiment Index is calculated at 0.65 for June 2018. This is a strong result. It bodes well for the sector.
该调查将于9月30日的季度再次进行。To join the panel please contact us.
