+For [[User:holmaschine|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.

+The picture above shows a 3D printed 2-part rocket.  65mm max diameter, 29mm motor bay, tangent ogive curve with internal 2-way structural ribs and support for airspeed sensor pitot tube at nose. Made on [[Type_A_Machine|our Type-A Machine]].
