Printing Materials

[APOModern]

Fairly new to the scene. I wanted to know what the extent of materials used are and what some of the more durable ones are. I've seen basic polymer in my classes and have read about Carbon Fiber and Kevlar, but am curious as to how strong and tough some things can really be made. Thanks.

Just do a google for 3d printer filament comparison. Here is a good site for info https://www.matterhackers.com/3d-pri...lament-compare

Wow thanks. This stuff has really come a long way since I first saw one years ago. I had no idea how many filaments and materials there are to be had.

Thank you for your information!

Because of the way 3d printing lays the plastic down, if you print in the right orientation, printed objects can actually stronger than injected while using less material.

In the last 12 months or so there have also been a number of super tough new filaments. The problem is that the cost is often related to strength :-)

PEEK for example - the genuine superman of plastics is in the order of $5-600 per kg.

Something like ninjateks Armadilo - a rigid polyurethane - is a lot cheaper and seriously tough.

Some of a printed objects strength is down to design, some is down to print orientation and some is down to material.

3d printing is as much - if not more - of an art than a science.

Hmmm interesting first point. I brought up "stronger" materials because a project I worked on kept cracking with basic plastic or polymer that a team mate used. I was trying to figure out what would have been better for next year's project. We were making locking blocks that housed polymer claws/hands with threads to bolt onto a metal chasis and they kept bending/busting. Sorry if that was a mouthful of info

For very strong filaments, the Taulman ones are great. Filaments have been tested on strength and some come out stronger than the carbon fiber / Mark Forged materials, including PC.

On the other side, there are now sculptable filaments such as Thibra.

Kai Parthy is another name to watch.

Some 3D printers can print metal. I've seen some that use aluminum and silver and etc

Got any examples?

Got any examples?

The metal X, The Renishaw, SLM solutions etc...
