Abstract

In this paper a system is introduced which makes 3D parts and patterns. These patterns are made up of metal droplets. The raw material is in the shape of wire. Molten droplets are generated in the droplet generator nozzle and deposit on a substrate having proper deposition rate, temperature and volume. By settlement of droplets on certain places beside and over each other in several layers, arbitrary 3D object is constructed. 60%Sn/ 40%Pb alloy is used as raw material in the experiments and it is possible to use different wires with various diameters and materials with a little change in the apparatus. Here the design essence of the constructed droplet based manufacturing machine is investigated. Furthermore the dependency of drop volume to apparatus factors is presented. Knowing the drop size is essential in making samples. Drop size is dependent to nozzle diameter, nozzle temperature and wire-feed velocity. Temperature and deposition rate of droplets are controlled in the system. Some droplets and simple parts that are produced by this apparatus are presented too.

液滴制造机的设计与制造

本文介绍了一个三维零件和图案制作系统。这些图案是由金属液滴组成的。原料是线状的。熔滴在液滴产生器喷嘴中产生，并沉积在具有适当沉积速率、温度和体积的基板上。通过水滴在若干层中彼此相邻或上方的特定位置上的沉降，可以构建任意的三维物体。实验采用60%Sn/ 40%Pb合金为原料，在仪器中只需稍作改动即可使用不同直径、不同材质的导线。本文对所构建的液滴制造机的设计要点进行了研究。进一步讨论了液滴体积与仪器因素的关系。知道液滴大小在制作样品中是必不可少的。液滴大小取决于喷嘴直径、喷嘴温度和送丝速度。在系统中控制液滴的温度和沉积速率。文中还介绍了该装置所产生的一些液滴和简单零件。
