<p>A liquid composition comprising: a) 5 to 25 parts of a monomeric aliphatic or cycloaliphatic di(meth)acrylate having a MW of not more than 800; b) 2 to 20 parts of a monomeric poly(meth)acrylate having a functionality of at least 3 and a MW of at least 610; c) 12 to 40 parts of a urethane(meth)acrylate having a functionality of 2 to 4 and a MW of 400 to 10,000; d) 35 to 70 parts of a monomeric or oligomeric di(meth)acrylate based on bisphenol A or bisphenol F; and e) 0.1 to 10 parts of a photoinitiator; wherein all parts are by weight, the total number of parts of a) + b) does not exceed 30 and the total number of parts of a) + b) + c) + d) + e) add up to 100. The compositions are suitable for the stereolighographic production of three-dimensional solid articles such as mechanical parts and models of body parts.</p> |
