What is the goal of CGtrader for 3D print models and new option for upload 3D print-ready object ?

On one hand you are right, but there was a blogpost on a topic. Like 'what is a 3D printable model, CGTrader thinks to be suitable for the competition": https://www.cgtrader.com/blog/2013/05/29/10-tips-for-modeling-for-3d-printing/.
But anyway, I like this competition. Of course, it is not that mainstream as a competition before, but I treat is a good way to encourage the artists to integrate a facility of 3D printing to their modeling work. What do you think?
Moreover, how do you like it all in all? Did you take a part?

Waiting for the answer!

my mystake.. i don't see this blogpost... so for cgtrader 'printable' mean ' can be print on shapeway service'... it is very restrictive...

Some of these rules are at best inadequate and at worst will cause problems if you try to apply them to a model that is optimized to be printed on a FFD printer

let take one : hollow.. hollow is good for shapeways/ sls system.. it reduce the cost of the material (resin and poweder are costly)..
for a FFD printer, it's bad as you can choose the 'infill' of the object (to reduce cost).. abs/pla are very cheap and the cost is minimum..
and it's bad because a good choice of the infill rate help a lot for overhang part (a problem that does not exist on shapeways printer) .. and to let cool the print (another problem that does not exist on shapeways printer) ...

another rule : the 1mm wall... it is a weakness of the shapeways printer /sls... this rule is a non-sense on a FFD printer..you can easily print a model with wall of 0.42mm thickness and the general good rule is a 2 perimeters wall aka : 0.84 mm for a nozzle of 0.35mm

size is again a non-sense : on shapeway, the size matter because you pay for a volume... on a ffd printed, the volume cost only time, and little money..
...

i hope to win the portfolio competition but as a great part of my models are optimized to be printed on FFD printer (' standard consumer product' i.e something that you can buy without the need to sell a arm ... ) ....we will see..

Hi othar,

Thanks for your thorough and valuable comments.

To answer your original question, the main goal of 3D print section on CGTrader is to have a broad selection of 3D print models with different options that a customer can choose from. This is just a starting point and we aware that there are a lot of things we need to improve before making it an effective repository for 3D print models. And from that perspective, your comments and suggestions are very helpful.

Similarly the competition was the first step to encourage designers to share their models and to introduce ourselves to the issues of the industry. For example, while there are many differences between FDM and SLS printing, we can supply both by adding filters like you suggest and quality control in place.

As you are an expert, it would be great to see here a tutorial or tips thread on the differences between FDM and SLS!

Thanks for your comment.. but beware...

The term fused deposition modeling and its abbreviation to FDM are trademarked by Stratasys Inc. The exactly equivalent term, fused filament fabrication (FFF), was coined by the members of the RepRap project to give a phrase that would be legally unconstrained in its use.
You can also use FFD [fused filament deposit] term. (I am used to using this term)

Othar, keep in mind that these guideliness, were provided on our blog in order to define what kind of 3D printable models are suitable to participate in 3D Printing Competition. So, among the variety of prizes we have such as 3D PrintUK that asks for particular dimensions to be able to print out the winning models. That's it.
On the other hand, it is nice that you have started such a topic on the forum. Moreover, when our digital library of 3D printable models is just at the launch stage, I guess it is important to hear all the advices and opinions. Thanks a lot!

3D printing is already in our life. Jewelry production is impossible without it!
