Question 2 The extruder head in a fused-deposition modelling machine has a diameter of 1.0 mm and produces layers that are 0.75 mm thick. Assume there is a 1 second delay between each layers and the porosity for the support material is 50%. The extruder head and polymer extrudate velocities are 30 mm/s. SECNON A-A Critical surface 3,00 Critical surface 22.50 42.00 40.00 Figure 1: Dimensions of product to be produced through the FDM process 2.1 Show with a sketch the most suitable build orientation for the product which will result in the best surface finish of the critical surface (shown in Figure 1), and the shortest manufacturing time. Provide reasons for the selection of the orientation. 2.2 Estimate the manufacturing time of the product (shown in Figure 1), through the FDM process, using the orientation selected in Question 2.1. 2.3 If the component is produced through the SLS process using a nylon material, how would this additive manufacturing process influence the build orientation and manufacturing time? Stipulate all assumptions made. 00'0€ 42.00 002 19,50 00
