【Desktop Metal将推出能批量制造飞机及汽车钣金部件的3D打印技术】据路透社9月7日报道,美国3D打印机制造商桌面金属(Desktop Metal)公司首席执行官Ric Fulop告诉路透社,该公司计划最早于周三公布一项新技术,将大大简化工业钣金生产过程。
Fulop表示,Figur G15技术可以直接从数字设计文件中按需成形标准钣金,从而消除了对冲压工具、模具、模床或冲床的需求,降低成本和生产周期。
“这是一个3000亿美元的市场,目前还没有数字解决方案。”
这家总部位于马萨诸塞州的初创公司的客户包括宝马、丰田以及亿万富翁埃隆•马斯克的火箭公司SpaceX。
3D打印技术可以用塑料或金属颗粒一层层叠加出复杂的形状,Fulop预计第一代新技术将用于飞机、农业和重型设备钣金零件的批量生产,在汽车组装领域,该技术将能够处理中低批量的钣金成型和冲压。
Fulop表示:“这项技术最初可以支持1万辆以下的年产量,我相信,在未来20年里,我们将大大减少冲压的必要性。”
该公司的一份声明称,目前该技术只能在其1.5米×1.2米的3D打印机设备中成形金属薄板部件,高度不超过40厘米。

Figure 1: Minimal Brain Dysfunction (MBD). Sub-spasticity of muscles. (A) Limited abduction of the hips - in result dysplasia. (B) Pedes plano-valgi, (C) Recurvation of the knees as an effect of shortening of the Achilles tendons, m. triceps surae. (D) Extension contracture of the spine. (E) Contracture of flexors of the hips. In result
„anterior tilt of the pelvis” and compensatory hyperlordosis of the lumbar spine. (F) Kneeing test - important in diagnosis. (G) Changed collagen in effect laxity of the joints.
Figure 5: (A) Example of advanced arthrosis in the left hip with heavy symptoms - pain, limping. In childhood never treated. (B) Both hips pain - in right hip because of permanent standing ‘at ease’ on the right leg.
Figure 6: Standing. Methods of physiotherapy as prophylaxis of arthrosis of the hips. A special form of standing and sitting should be introduced at the age of 45 - 50. Standing in abduction and in internal rotation, like in karate changes the loading on the femoral heads, enables regaining internal rotation. Such standing - every day in every situation over many years is very beneficial
Figure 7: Sitting. Methods of physiotherapy as prophylaxis of arthrosis of the hips. A special form of standing and sitting should be introduced at the age of 45 - 50. Sitting - in internal rotation, what increases the range of this movement. Patients should sit in this position every day in every situation. Sport in the form of „Nordic walking” is also very important.

天氣太熱了. 來學一個很有趣的片語吧.
(être la) cinquième roue du carrosse. 電燈泡或是無用或多餘的人. 因為車子只需要四個輪子. 第五個輪子可有可無. 所以常會在一對情侶中的第三個人一起出去玩時會覺得好像自己是透明的. 就可以用這個片語.
cinquième roue du carrosse \sɛ̃.kjɛm ʁu dy ka.ʁɔs\ féminin singulier
(Figuré) Quelque chose ou quelqu’un de trop, qui ne sert pas à grand-chose, voire à rien.
Quand on est seul avec deux couples dans des activités à quatre, on se sent un peu comme la cinquième roue du carrosse.
Pourtant le Cinquième Bureau passait pour la cinquième roue du carrosse. — (Vladimir Volkoff, Le Berkeley à cinq heures, 1993)
Quelle raison aurais-je de fréquenter chez vous ? J’ai de l’amour-propre. Tout le monde n’apprécie pas d’être la cinquième roue du carrosse. — (Anton Tchekhov, Polinka, traduction Anne Coldefy-Faucard, Librio 698, 2004, E.J.L.)
