Stereolithography (SLA)

Stereolithography (SLA) is an industrial 3D printing process used to create concept models, cosmetic prototypes, 和复杂的零件与复杂的几何形状在最短的一天. A wide selection of materials, extremely high feature resolutions, 和高质量的表面处理是可能的SLA.

How Does SLA 3 d打印技术 Work?

SLA机器开始绘制支撑结构的层, followed by the part itself, 用紫外激光瞄准液体热固性树脂的表面. 在树脂表面成像一层后, the build platform shifts down and a recoating bar moves across the platform to apply the next layer of resin. 这个过程一层一层地重复,直到构建完成.

Newly built parts are taken out of machine and into a lab where solvents are used to remove any additional resins. When the parts are completely clean, the support structures are manually removed. From there, parts undergo a UV-curing cycle to fully solidify the outer surface of the part. The final step in the SLA process is the application of any custom or customer-specified finishing. Parts built in SLA should be used with minimal UV and humidity exposure so they don’t degrade.

ABS-Like半透明/透明(WaterShed XC 11122)

ABS-Like半透明/透明(WaterShed XC 11122) offers a unique combination of low moisture absorption (0.35% 0.每ASTM D570 25%)和接近无色透明. 为了使功能部件清晰,需要进行二次操作, 这部分也将保留一个非常浅的蓝色色调之后. 而适用于一般用途的应用, 分水岭是流可视化模型的最佳选择, 光管, 和镜头.

Primary Benefits

  • SLA树脂的吸湿率最低
  • Functional transparency
超细™ (灰色的 and Green)

超细™ is a custom formulated material available in gray and green that is exclusive to Protolabs. This ABS-like thermoset is printed in Protolabs’ customized machinery to achieve high resolution features as small as 0.002 in. MicroFine是理想的小零件,一般小于1英寸. 由1. 由1. In terms of mechanical properties, MicroFine falls in the mid-range of SLA materials for tensile strength and modulus and on the low end for impact strength and elongation.

Primary Benefits

  • Produces highest resolution parts
  • Ideal for extra-small parts
PP-Like半透明白色(Somos 9120)

PP-Like半透明白色(Somos 9120) is the most flexible SLA option outside of Carbon RPU 70 and FPU 50. 与注塑成型聚丙烯的平均值进行直接比较, 9120 has similar tensile strength, tensile modulus, flexural modulus, and impact strength. 唯一不同于模压PP的是它的延伸值, 只有25%的成型热塑性塑料.

Primary Benefits

  • 半弹性
  • 半透明
类似pc的高级高温(Accura 5530)

类似pc的高级高温(Accura 5530)创建强大, 刚性部件,耐高温. 热固化后的选择可以将HDT在0℃时提高到482°F.46 MPa加载. 在所有未填充SLA材料中,Accura 5530具有最高的e模量, 而且它以耐汽车液体而闻名. 然而, 热固化过程确实使Accura 5530不那么耐用, 导致伸长率降低50%.

Primary Benefits

  • High elastic modulus
  • Higher resistance to heated fluids
类似pc的半透明/透明(Accura 60)

类似pc的半透明/透明(Accura 60) is an alternative to the general purpose ABS-like materials and WaterShed XC 11122 when 刚度 is desired. 像分水岭, this material can be custom finished to achieve functional transparency with secondary processing. Accura 60 has the highest tensile strength of and elastic modulus compared of all SLA materials outside of the Advanced High Temp options that are most often thermal cured.

Primary Benefits

  • 高刚度
  • Functional transparency

类似陶瓷的高级高温(执行) exhibits the highest tensile strength and E-modulus making it the stiffest performance material of the SLA materials. 当热固化选项应用于由PerFORM制成的部件时, 它表现出最高的HDT(高达514°F在0.负载46 MPa)的SLA材料.

Primary Benefits

  • Stiffest SLA resin
  • Highest HDT of SLA resins
