By saying that a competitor offers something that we don't, you are promoting them. We do not allow promotion of competitors on our forums. We allow constructive discussion of Shapeways related content on our forums. Discussion relevant to the post is also preferred. If you wish to constructively discuss polished black strong and flexible's availability as it pertains to Shapeways, by all means carry on.


Other view: By saying that a competitor has something interesting and very useful to us we want to put your attention on it. Most of us were not here if we don't think that SW is providing a great service.
(Don't want to make a principal discussion out of that, but in the last time SW put a lot of changes to us shop owners and designers causing a lot of work or business case adaptations needed for SW to improve their business. It's once more time top pay also attention to us!!)

Wow, so my comment gets deleted even talking about how ridiculous deleting comments were on this thread? NICE. I didnt say anything about a competitor or personal attack.

For those that missed it was basically this:

Pointing out a competitor has something that SW dose not is not promoting the competitor. Its pointing out a difference. Being so uptight that someone else here even mentions a competitor is seen as promotion, is ridiculous.

My example was simple. Its like going into you fast food taco place and asking for a beer. But the sales person says they dont have beer, they have been working on it for 3 years but just cant keep it cold so we are not selling it. Then another custom says I know a taco place down the street that sells beer, there name is -----. Suddenly the SW moderator, oh I mean taco chain employee reprimand the customer for actively promoting other business while in their establishment and is kicked out the door.

That is how ridiculous SW is by accusing a SW member of trying to sell you out just by the mere mention of a competitor. But why was my posted deleted? I didn't mention a competitor. Maybe it was my comment that we can land a robot on a comment billions of miles away but SW is still working on how to print black plastic? Well news flash, it's not an insult, it just happens to be fact.

I am sure this message will be deleted by morning, but it's worth restating for those who read it in time. I am really surprised the mods here are so touchy. Cant even comment about a comment.

I meant I wanted to see Black Strong and Polished.. Once it's polished you lose the flexibility -they seem to go hand in hand I think.


I do not see why polishing would remove the (limited) flexibility of the material, that being an inherent property of the nylon material. As I understand it, the problem is that dyeing the polished white material black would lead to uneven and non-reproducible coloring as the polishing itself cannot be uniform and "black" dyes (as opposed to pigments) are actually a mix of several dark dyes each with a reddish or blueish color hue. (This is also likely to preclude the "gray dyed" SF material some people have voiced interest in - that one would not be a uniform gray either, but full of light, dark or even slightly colored patches.)
What shapeways would have to do, and what some of their competitors seem to use, is operate a dedicated printer and tumbler combo with EOS' black-pigmented PA2202 material for a "black strong and flexible/polished" (assuming soot pigmenting of the raw material does not alter surface properties so much as to make polishing impossible). I do not know if there are third party suppliers of nylon powder that is pigmented gray, EOS themselves do not appear to offer it (except "alumide") and other printing service seem to offer it in conjunction with FDM only, not SLS.

For non-flexible (and probably somewhat brittle) black parts one could probably try the "Black Detail" acrylic.

Hi,

I have a print I want to make that has many multiple parts, and with the current charges of $1.50 for each separate part, I want to have sprues that join multiple parts together.

I modelled my parts in SolidWorks and have placed all the parts together in the same Assembly file, and have created seperate sprue parts that join my desired print parts. However, when I upload it to Shapeway, it still recognizes the file as multiple individual parts.

Is there anything I can do so my file gets recognized as less seperate parts?

Thanks.

Make sure that the sprue is actually touching or slightly intersecting the pieces - if shapeways still counts them as separate parts, there must be a minuscule gap left at the interfaces. Assuming STL format, try checking your file with netfabb studio basic (freeware from netfabb.com) or run it through the netfabb cloud service (hosted on windows azure nowadays, so needs a microsoft acount, but otherwise still free as far as I know)

Hi,

Thanks for the prompt reply. The sprue parts are intersecting the desired print parts quite significantly in my assembly file.

I am not familiar with netfabb, I have the basic version downloaded. What am I looking for in the programme to indicate whether the parts are separate or not?

Run the "Standard analysis" from the "Extras" menu (or start the "Repair" - also visible as a red cross on the toolbar), it should tell you the number of separate shells. Possibly the problem is caused by invalid geometry (e.g. coincident or misoriented faces) that shapeways' automated software tries to "fix" by removing the offending area of your model.

Exactly, it's important to ask for references and examples,
when dealing with potential clients.

I usually show my examples at:

Hi,

I would suggest not to make any upfront payment unless you get to see some progress of your project.

Regards,

I just got my Christmas Grumpy Cat Ornament back from Shapeways in Full Color Sandstone. It turned out really well! The Sandstone is the perfect texture- he looks like he'll come to life any moment! It can be used as a bauble or Christmas tree topper....

It'd be fantastic for me if you'd consider featuring my ornament and/or my shop which contains a bunch of original, colorful designs that I think could make great stocking fillers...

Thanks for looking and have a great Christmas!

Best wishes,
Matt
