For holmaschine, 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.
