![]() Parts produced from a 3D printed mould can have their layer lines removed using abrasive paper if required. Curing and FinishingĪfter curing at room temperature for around 24hrs, the part can be demoulded and any flashing or nibs removed using abrasive paper. The compression needs to be done gradually over a period of a several minutes to allow time for the excess resin to escape. ![]() Once the moulds have been loaded with fibre and resin the two mould halves can then be compressed together, This clamping can be done with either a bench vice, G-clamps, or a press. This will appear to mean overloading the mould cavity, which is the reason why the mould needs to be designed with some 'compression space'. The chopped carbon fibre tow and low viscosity epoxy should be accurately weighed and loaded into the mould. Any holes or bolt threads should be sealed or smoothed using filleting wax (also included). Mould Preparationīefore laminating, all mould sections should be prepared using multiple applications of RW4 spray release wax (included in kit). ![]() See also our tutorial on resin casting a two-part compression mould. These compression moulds can be made by 3D printing, resin casting or CNC machining, as described in the tutorial. In order to use this kit to produce forged carbon fibre parts, you will require a set of moulds designed with compression moulding in mind. The kit includes 750g of CT12 chopped tow and 1kg of IN2 epoxy infusion resin, which provides enough material to produce of 1kg (or 1.4 litres) of solid carbon components.
