The invention concerns a method for producing a three dimensional object in particular an artificial tooth by stereolithography wherein a liquid photocurable resin composition is cured by light. Said photocurable resin composition contains based on the total weight of the photocurable resin composition (i) from 90 to 99.9% by weight of a radical polymerizable organic compound (A) selected from radical polymerizable monomers oligomers pre polymers and mixtures thereof and (ii) from 0.1 to 10% by weight of a photosensitive radical polymerization initiator (B). Said radical polymerizable organic compound (A) comprises based on the weight of the radical polymerizable organic compound (A) from 0.5 to 20% by weight of a polyrotaxane compound comprising a polymer chain selected from polyethylene glycol (PEG) polypropylene glycol (PPG) polyethylene glycol polypropylene glycol (PEG PPG) block copolymer or polydimethylsiloxane (PDMS) onto which the cyclodextrin ring(s) is/are slipped and wherein the cyclodextrin is derivatized with at least a radical polymerizable group. The invention also concerns a relative liquid photocurable resin composition and articles produced thereby.
