The textured surface itself adds effective draft\u2014a coarse texture (VDI 33+) might need an extra 1.5\u00b0 per 0.025 mm of texture depth.<\/p>\n<p>Gate design for ABS typically favors edge gates or submarine gates for aesthetic parts, and direct sprue gates for structural parts where gate vestige is acceptable.
