Printing with support

This resource is for the slightly more advanced. It introduces the idea of printing using support material for more difficult or complex objects

Thin Walls… testing the limits

Over the last few weeks I’ve been playing with all sorts of settings and software to try to really get to grips with what they really mean. I got frustrated by doing large prints so I designed a couple of objects along the way that allowed me to see results quickly. The square and diamond are simple 25×25 parts that allowed me to check on solid surfaces (shells and surface layers at 0, 45, and 90 degrees.

But what was really starting to frustrate me was printing objects with thin walls (containers). Walls that were really thin were not printed, quite thin walls ok, and thick walls were no problem… it was the ones in between that were proving difficult.

So I designed a “Walltester” with walls from 0.1 to 2.0mm in 0.1 increments and also 2.5 and 3.0mm for good measure. This allowed me to see…

The smallest wall size that is processed

Walls that print as a single line

Walls that print as 2 lines side by side

Walls that print as 2 lines with a gap

Walls that print as multiple lines

Walls that print as multiple lines with zig zag infill

The full details of my testing can be seen on the Bits from Bytes forum http://www.bitsfrombytes.com/forum/post/thin-walls-testing-limits You can also download the “walltester” which is on the BfB wiki http://wiki.bitsfrombytes.com/index.php/Test_Parts

I don’t think my testing was totally scientific or the results were conclusive but I certainly enjoyed finding out what was possible and gained a better insight into the capabilities of the various software packages… and also what I can and can’t do with my shiny new RapMan.

 

 

Blast off!!

How about designing and printing your own rocket…. a real one that flies! Ok so this project is about using sodium bicarbonate (baking soda) and vinegar to produce CO2 to power a model.

“How to” video…. changing settings in BfB Axon

In the previous post I announced a new video explaining how to use BfB Axon. … Here is another “How to” video that shows how to make new profiles and change settings in Axon.

The video can also be viewed on YouTube Best viewed in HD and full screen.

Other “How to” videos can be found on the BfB Wiki  and more T&L resources are available

“How” to video… using BfB Axon

BfB Axon is a fantastic “free” program to generate the g-code to drive your RapMan or BfB3000 printer.

You can convert any .stl file generated in your 3D design software or downloaded from the internet
