Abstract: A method and preferred apparatus (10) to cut a preform material which is biodegradable and preferably dispersible in water, to produce a shaped article, is described. The cut is produced without producing harmful fumes or leaving a harmful residue and preferably without charring at the cut. Preferably, only small amounts of carbon dioxide and water are produced at the cut. Shaped articles which are in sheet or block form or which are for 2-D or 3-D shaped article formation can be produced.
