What is the 3D printing community/group looking for?

Hi Nate,

I agree, it did look like an interesting experiment, i.e. galvo's, immiscible liquids etc. I personally I don't believe for a minute that the video that stated his partner had stolen the funds represented the genuine situation. Also a BBC report mentioned they contacted his partner (who Rylan accused of all the troubles) and he claimed it was an untrue statement under duress. So one of them at least is lying to some degree, and possibly both. Maybe his partner paid it all back with interest, we only have Rylan's word that he didn't.

It is possible to do so much with $1M, or even a fraction of that. A lot of startups work with $30k or less in exchange for just 2% of their business, and only when they have shown sufficient progress would investors touch it beyond that. It seems that Kickstarters provide their backers with the worst of everything, massive risk and very little they can actually do when problems like this occur

Correct Nate, this will be dedicated article, as need a series of specific consideration. Unfortunately most of the users does not consider factors that has serious influence on the sliding choices, coming from the physics of fluids, material characteristics and many other things.

Anything new?  All the discussion on 3D printers with Father's Day events made me think of this thread!  :-)  Since I doubt I will get one for Father's Day the low cost build along is very much an interesting topic!

By my side, as soon as possible I will continue with the tips and tricks, everyone based on a different production with different difficulties. These days are compulsive and I am living in a bottleneck!

Microsoft Virtual Academy did a 3D printing essentials series. It's been pulled from MVA but is still available on channel 9:

It may be of interest to some people starting out.

I tend to use Nemetschek Vectorworks Designer for 3D modelling. I think that the general modelling in 3D aspect is not too difficult and there probably are plenty of vendor tutorials on using the specific application however it is more the considerations you then have to apply to the model for it to become a successful 3D print.

I've been working on a project design recently which will be externally printed through 3DHubs, so I don't know what machine it is going to end up on or the associated quirks. I've therefore created the 3D design so that it doesn't require any support structures and to keep tolerances fairly flexible, which will mean additional work after printing. However, recently I've seen some talk of using support structures which can be dissolved in soap solution, so presumably this is done with a two filament machine and potentially makes designs less restrictive.

Guidelines for tolerances for fasteners would be quite useful. This project I've just done pilot holes which will need to be drilled and countersunk after printing, but perhaps it is possible to avoid that extra work. Perhaps accuracy is now good enough to use something like threaded inserts straight after printing.

An overview of various tried and tested construction techniques might be useful. I suspect a lot of this may follow traditional woodworking joins but once again we need to know how machine/material tolerances are going to affect this. My recent project was done in two halves which will be butt jointed together allowing the use of a gasket as a spacer if necessary, however I did initially think about a lap joint for a neater finish and easier assembly.
