3D打印耗材层间开裂的原因及解决方法

    3D打印耗材打印模型会出现层间开裂的情况，下面eSUN易生来具体分析：

    1.打印开裂翘边

    ①材料：ABS、ASA、PA、PC等3D打印耗材材料收缩率较高，容易翘边开裂，打印时需要具备恒温腔，可以使用eEnclosure或者带加热腔体的打印机；    ②切片：需要关闭吹料风扇，吹料风扇会加速材料冷却，引起翘边和开裂；    2.使用时层间强度较差    ①材料：部分3D打印耗材的材料层间强度较差，如ePA-CF，可以适当通过切片优化强度，应选择合适的模型摆放角度，避免实际使用时Z轴方向受力    ②切片：增加打印温度和填充率、降低打印速度和层厚、适当关闭吹料风扇，可以提高模型层间强度。    文章转载自eSUN易生3D打印耗材https://www.esun3d.net/cn/LED">SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=3%3A32%2C4%3A32%2C8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&dt=1640933831001&bpp=8&bdt=397&idt=107&shv=r20211207&mjsv=m202112060101&ptt=9&saldr=aa&cookie=ID%3D43034ac24d9e811c-228692c30bca0020%3AT%3D1624939011%3ART%3D1624939011%3AS%3DALNI_MZWxenOYS1cgSk6XYTy3-XU2V_STA&nras=1&correlator=387113712534&frm=23&ife=1&pv=1&ga_vid=2109282818.1640933831&ga_sid=1640933831&ga_hid=467781312&ga_fc=0&nhd=1&u_tz=480&u_his=6&u_h=864&u_w=1536&u_ah=824&u_aw=1536&u_cd=24&u_sd=1.25&DMC=8&adx=-12245933&ady=-12245933&biw=1519&bih=706&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31063824&oid=2&pvsid=3186286676196709&pem=878&tmod=189&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1536%2C0%2C1536%2C824%2C730%2C360&vis=2&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.e5ih1lukfvcb&fsb=1&dtd=126" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.e5ih1lukfvcb" data-load-complete="true">
