- | For me, the advantage of 3-D printed model rocket parts is the ability to create a very thin and structurally efficient shape without concern over fabrication and the relative alignments of subparts. Components can be printed true to final form (+/-) with only light treatment required to smooth outer surfaces so long as the basic restrictions of the manufacturing method are understood. | ||

'''Nose Cones''' | |||
Several prototypes have been created in both 29mm and 65mm diameter, using a tangent-ogive profile. | |||
TO DO: write code to generate g-code directly instead of using SolidWorks and Slic3r. | |||
WHY: avoid 15 min + delay time using slicer, better match to theoretical shape without. | |||
TO DO: Model payload supports integral with structural elements. | |||
WHY: Reduce number of fasteners and/or adhesive required. | |||
'''Fin Cans''' | |||
One prototype printed, downrated to smaller engine size until proven. Will mount adapter to aft bulkhead using (4) #4-40 screws. | |||
