摘要:
研究了烧结件系统参数如激光功率、铺粉密度对烧结件密度的影响,总结了提高烧结件密度的方式,从而实现提高烧结件力学性能的目的.在基于对快速成型加工方法(特别是选择性激光烧结SLS)进行深入的研究后,为解决以高分子粉末材料为基底的烧结件力学性能较差的问题,采用系统最佳参数烧结成型测试件,并对其进行渗树脂处理,并对原型件和经过处理的试样分别进行了力学性能测试,包括压缩性能、拉伸性能、弯曲性能测试等,得到机械性能为原型烧结件3~4倍的增强烧结件,为提高成型件的力学性能提供了新的途径.
Abstract:
Th is paper presents the effect of SLS processing param e ters on the as-sin tered sam ple and obta ins the opt-i m um pa rame ters. After a pro found research based on the process ing me thod of qu ick tak ing shape ( esp. Se lective Laser S intering), in order to so lve the problem ( ie. , the poo rm echanic capab ility of sinter ing product ofM ac rom o lecu le pow derm a terial), a co lophony re in fo rc ing treatm ent is g iven to the sin tering or ig ina.l The test o f them echan ica l properties is done of the as- sinter ing samp les wh ich are processed under the optim um param eters, inc lud ing stretch test, rig idity and so on. The re inforced sintering sam ples are obta ined whose m echan ic properties is 3 to 4 tim es tha t of the or ig ina l sinter ing sam ples, wh ich provides a new w ay to increase the m echan ic properties o fm ou ld ing sam ples
