TASKS: The startup WEB-3D is offering a 3d printing service for plastic parts base on the FDM process. They are using 2 Ulimaker 3 extended and 2 Flashforge Creator 3 printers.: Ulimaker 3 extended 3.054,00 EUR 3.664,80 EUR 4 a Flashforge Creator 3 4.412,54 EUR 5.295,05 EUR 6 a Maintenance cost per year 120 EUR 100 EUR Miscellaneous cost per year 140 EUR 160 EUR Occupied lab space 2 m 2 m The startup is calculating with a calculatory interest rate of 4,96% and linear depreciation. The printers are used for 3 materials in random mix: PLA black 49.988 cm 3D-Printer Investment Replacement value Expected economic lifetime 3D-print volume Scrap rate on printing vol. Filament price per volume Printing speed per volume Printing energy consumption Time for cleaning and distribution Turnover 5% 0,054 EUR/cm 10,4 cm/h 244 W/h 10.400 h/m 29.972 EUR Accounting area Material incl. material handling TPU black 9.960 cm 3D printing Energy consumption during 3D-printing Cleaning and shipment of the parts 10% 0,075 EUR/cm 12,0 cm/h 300 W/h 15.000 h/m 6.500 EUR The printing speeds for the 3 materials are applied to all 4 printers. The printing energy consumption for the 3 materials is the same on both printer types. The scrap rate is applied to the 3D-printing and before cleaning and distribution of the parts. (scrap rate on 3D-printing, no scrap on cleaning & shipment, no scrap shipped) For the 4 accounting areas the company has total costs of: PETG black 19.980 cm 15% 0,100 EUR/cm 15,0 cm/h 360 W/h 15.000 h/m 16.000 EUR cost 6.000 EUR 8.000 EUR 600 EUR 17.600 EUR d.) The company would like to optimize their profit by an improved ratio between the production volume of the 3 different plastics. The bottleneck machine is used for the cleaning of the parts before shipment and has a maximum capacity of 1.000 h. Assume that the cost for the 3D-Printing are fixed cost. For the calculation use the additional information about the costs per unit, time consumption on the bottleneck machine, minimum required sales volume and maximum possible sales volume according to the table: Material cost per unit Energy cost per unit Cleaning & shipment cost per unit Time for cleaning without shipping Minimum required sales volume Maximum possible sales volume PLA black 0,054 EUR/cm 0,014 EUR/cm 0,250 EUR/cm 8.000 h/m 30.000 cm 80.000 cm TPU black 0,075 EUR/cm 0,016 EUR/cm 0,300 EUR/cm 10.000 h/m 8.400 cm 15.000 cm PETG black 0,100 EUR/cm 0,020 EUR/cm 0,300 EUR/cm 10.000 h/m 20.000 cm 40.000 cm Calculate the sales volume for the 3 different plastics that will achieve the maximum profit for the company if the capacity on the bottleneck machine is fully used! (20 points) Calculate the improvement of the profit by the optimized production ratio between the 3 different plastics!
