"Hi John,
it seems we are looking at things from a different perspective.....3D printing for use as rapid prototyping has been around as an industry since the early 90's, that was what I was referring to. You are quite right that it has…"

Oliver commented on Chris Anderson's blog post Where drones sit on the "hype curve""Well I'm not sure how accurate this is....3D printing on the peak of expectations...Really!...well I would of thought they are 10 years out of date at least.....In my opinion 3D printing is surely on the slope of enlightenment.....Now if they…"
Oliver posted a discussionDesigning a rotary UAV for commercial film work
Hi Guys,I am doing some research into applications for rotary UAV's just out of curiosity really.If you were designing a rotary UAV for commercial film work, what camera would you want to use and why? What is the weight of a typical payload? Also what is a typical "mission profile" for a UAV used on commercial film sets? Would you need to use a specific industry standard video camera, would it need to be gimballed for setting up shots? Does it really need to fly autonomously or would FPV work…See More
"If you're talking about pourable foam mouldings, consider using the printed part as a disposable mould - print from PLA or some form of disolvable material. Pour the foam interior and then strip off the printed material - a la shell…"
Oliver replied to Oliver's discussion Printed wing concept"Hi Andrew,
You are right......as with everything the design is a compromise....if you print parts from the standard ABS material it's hard to make them stiff and strong enough....
This link shows somebody doing what I have wanted to do…"
"I see what you are trying to do Oliver and it is indeed pause for thought, but going for broke with printing the entire thing, I am struggling to see how you can avoid winding up with an airframe with next-to-no payload.
On the other hand, a…"
Oliver replied to Oliver's discussion Printed wing concept"Hi Andrew,
Thanks for your reply,
you are right about what you say, the honeycomb structure is no good for wing designs as I have shown it...You are also right that its hard to beat Balsa as a lightweight material......but thats not quite what…"
"It looks like a nice idea until you analyse it closely. The honeycomb adds a lot of weight and stiffness for construction loads, but little benefit, in my opinion, for flying loads.
I have spent some time analysing construction methods for the…"
