熔模铸造
Investment CastingA manufacturing process used for producing complex metal parts by creating a wax or plastic pattern, investing it with refractory material, and then melting the pattern out to leave a cavity. / 一种用于生产复杂金属零件的制造工艺，通过制作蜡或塑料模具，将其用耐火材料包裹，然后熔化模具以留下空腔。

Aluminum Casting ProcessPorosity FormationDefect Reduction
Main parameters and performance indicators
pouring temperature: 700–800°C (optimal range 720–760°C)mold-filling time: affects porosity formationgating-system design: separating gating system recommended
Open problems
Residue from PLA burnout (~43.6%) negatively affects mold qualityHigh gas solubility and turbulence at higher temperatures increase porosity
