Anordning ifølge et hvilket som helst af kravene 12 til 16, der endvidere omfatter en styreenhed, der er operativt forbundet med bæreren og lyskilden, til at føre bæreren væk fra byggepladen under eller efter polymerisering af væske i byggeområdet; eventuelt hvor bæreren omfatter et drev, hvor drevet og styreenheden er konfigureret til at føre bæreren ensrettet væk fra byggeoverfladen.
18. Anordning ifølge et hvilket som helst af kravene 12 til 17, hvor bæreren har et opløseligt offerlag derpå, og den tredimensionelle genstand er dannet på det opløselige offerlag.
19. Anordning ifølge et hvilket som helst af kravene 12 til 18, hvor det semipermeable element omfatter en fleksibel polymerfilm, og byggepladen endvidere omfatter et spændingselement forbundet med polymerfilmen og til at fiksere og størkne film.
20. Anordning ifølge et hvilket som helst af kravene 12 til 19, hvor det semipermeable element omfatter: (i) et polymerfilmlag med en topoverflade, der er placeret til at komme i kontakt med den polymeriserbare væske, og en underoverflade, og (ii) et stift, gaspermeabelt, optisk transparent støttende element, der er i kontakt med undersiden af filmlaget.
