摘 要：
[目的]探讨将快速成型技术应用于木材/金属材料的复合的可行性。[方法]利用三维打印原理,以金属和木材的粉末为原料进行材料复合。[结果]试件抗压强度高,试件被压后,并没有马上崩坏,而是逐渐被压扁。7组试验的试件压缩前后相差不大。故试件材料的塑性较好,塑性的大小与试件制作过程中粘结剂的用量多少有关,粘结剂用量越多,试件材料的塑性越大。随着金属粉用量的减少,试件的电阻逐渐增大。在相同比例下,粗木粉试件的电阻要大于细木粉试件的。金属粉越多,材料的导电性越好;粉末颗粒的大小能影响材料的电阻。粉末粒度越小,材料的导电性越好。[结论]基于快速成型技术的木材/金属材料复合新方法是可行的。

摘 要：
[Objective] The purpose of the research was to discuss the feasibility of applying rapid prototyping technology in the recombination of wood-metal material.[Method] With metal and wood powders as raw materials,the three-dimensional printing principle was applied in their recombination.[Result] The specimen had high compressive strength.After it was compressed,its dilapidation did not happen at once,but it was squashed gradually.The non-compressed and compressed specimens had little difference in the 7 experimental groups.So,the plasticity of specimen material was better and related to the dosage of binder used in the making process of specimen,the more the used binder was,the greater its plasticity was.As the dosage of metal powder was reduced,the resistance of specimen was increased gradually.Under the same proportion,the resistance of specimen made from crude wood powder was greater than that of specimen made from fine wood powder.The more the metal powder was,the better the conductivity of material was and the size of powder particle could influence the resistance of material.The smaller the particle size of powder was,the better the conductivity of material was.[Conclusion] The new method based on rapid prototyping technology of recombining wood-metal material was feasible.
