The expert thinks: 3D printing has become a manufacturing new favorites, theoretically what can "play", but at this stage should not blindly launched 3D print making, and application in the independent research and development of the "cutting edge", "Chinese create" ability to quickly upgrade.

在卢秉恒主持的快速制造国家工程研究中心，通过3D打印为企业进行产品研发，已覆盖从手机到电视的各种电子产品，所见即所得，且可感可触，“这种研发速度甚至可以达到原先10倍”。

In Lu Bingheng the auspices of the National Engineering Research Center of rapid manufacturing, through the 3D the print product research and development for the enterprise, has covered from the mobile phone to a variety of electronic products, TV, WYSIWYG, and can be touched, "the research and development speed can even reach to the original 10 times".

“在缩短研发周期和成本方面，3D打印相对传统模具制造具有天然优势。”国际模协秘书长罗百辉表示，目前世界三大汽车制造商均已靠3D打印来设计样车，几乎所有的车身外形都可由此快速成型，车辆材质从塑料到树脂，再到塑料、树脂之外喷涂一层金属，形成过渡模具。借此工艺可以打造十几辆3D样车，用于造型、风洞、碰撞、道路等多重验证，“研发周期只有原来的1/3到1/5”。

"To shorten the development cycle and cost, 3D printing relative to traditional mold manufacturing has a natural advantage." International model assist secretary-general Luo Baihui expresses, at present, the world's three largest car manufacturers have been on 3D print to design prototype, almost all of the body shape can be so rapid prototyping, vehicle materials from plastics to resin, then to plastic, resin coating a layer of metal mold, forming a transition. This process can create a dozen 3D prototype, used for modeling, wind tunnel, collision, roads and other multiple validation, "the research and development cycle is only the original 1/3 to 1/5".

一家车灯企业接了标书，48小时内就打印出了车灯初样。当其他两家竞标企业设计出车灯模具，已是两个月之后——显然，第一家企业“先到先得”。

A lamp enterprises received tenders, 48 hours just print out the lamp mould. When two other bidding companies design mould, was two months later, apparently, the first enterprise "first come first served".

在智能制造专家看来，制造业大批引进3D打印设备，用于扩大产能，既不现实也无必要，3D打印适合打印特殊复杂的小批单件，这一特点正符合企业个性化研发要求。

It seems that in intelligent manufacturing experts, manufacturing a large number of the introduction of the 3D printing device, used to expand production capacity, is neither realistic nor necessary, 3D print suitable for print special complex small piece, this characteristic is in line with the requirements of personalized research and development enterprise.

我国汽车、发电设备、拖拉机、工程机械等产量均已居世界第一。在汽车和航空领域，在汽车和航空发动机设计制造时，需要设计一个金属球状的关键构件，采用传统铸造、切削加工，靠的是类似雕塑的“减法”；但因为是个十分精密的空心球，3D打印就更为适合，工程师只需确定球内一圈一圈的内径，就能将金属材质一点点堆叠上去，靠类似陶器制作的“加法”。

Automobile, power generation equipment, tractors, construction machinery and other production in China has ranked first in the world. In the automotive and aviation fields, in the manufacture of automobile and aircraft engine design, need critical component design of a metal spherical, using the traditional casting, machining, relies on similar sculpture "subtraction"; but because it is a very sophisticated hollow spheres, 3D printing is more suitable, engineers only need to determine the ball in a circle around the inner diameter of the metal material, can be a little stack up, by similar pottery "additive".

数据显示，在3D打印设备的产量上，美国现占全世界71%，欧洲占12%，以色列占10%，中国只占4%。这种设备的拥有量在一定程度上标志着国家创新能力。

Data show that in the 3D printing equipment production, the United States now accounts for 71% of the world, Europe accounted for 12%, Israel accounted for 10%, China accounted for only 4%. Ownership of this equipment marks the national innovation ability in a certain extent.
