Which material is strong, light and cheap at the same time?

Question

Quadcopter

Hello!
I want to make a frame for a quadrocopter on order (a personal project, there are no such frames for sale)
Can anyone advise the material from which it can be made?
Four things are required from the material:
1) strength
2) lightness
3) relative cheapness
4) the ability to order 3d printing of a part from this material (in other words, to realize the part)
Plastic is not suitable, since it is not very strong and not so light
I think it should be some kind of metal
Tell me who knows :)

Answer 1

The simplest is some kind of carbon-containing composite (maybe even fiberglass will do). Various aluminum alloys. Expensive - titanium.

Answer 2

wood

Answer 3

It is advisable to choose a frame for a quadcopter from lightweight and durable materials such as plywood and fiberglass. This is a great platform to start with. To lighten the weight, it is advisable to use nylon bolts and washers.

Answer 4

You need to look at the websites of aircraft builders and aircraft modellers, they know all this there. Especially look who makes Real planes, they understand the materials
