【摘要】：基于選擇性激光燒結(jié)(SLS)技術(shù),在不同工藝參數(shù)組合下,分析了激光掃描速度、激光功率、分層厚度、掃描間距以及預(yù)熱溫度等工藝參數(shù)對(duì)SLS原型件強(qiáng)度與尺寸精度的影響。研究結(jié)果表明,各燒結(jié)工藝參數(shù)均會(huì)影響原型件的燒結(jié)強(qiáng)度和尺寸精度,且各因子之間存在交互作用。當(dāng)激光功率為40 W、掃描速度為2500mm·s~(-1)、掃描間距為0.15mm、分層厚度為0.20mm、預(yù)熱溫度為60℃時(shí),燒結(jié)強(qiáng)度與尺寸精度達(dá)到最優(yōu)。在此基礎(chǔ)上,結(jié)合傳統(tǒng)砂型鑄造方式,實(shí)現(xiàn)了全新高端工程機(jī)械液壓多路閥的快速鑄造,驗(yàn)證了基于SLS技術(shù)的快速鑄造液壓元件的可行性。
[Abstract]:Based on the selective laser sintering (SLS) technology, the effects of laser scanning speed, laser power, delamination thickness, scanning spacing and preheating temperature on the strength and dimensional accuracy of SLS prototypes were analyzed. The results show that each sintering process parameter will affect the sintering strength and size accuracy of the prototype parts, and there is interaction between each factor. When laser power is 40 W, scanning speed is 2500mm s ~ (-1), scanning distance is 0.15 mm, delamination thickness is 0.20 mm, preheating temperature is 60 鈩，
