Well here's my submission although for some reason the colours in the preview images look real washed out like this:

http://twistedpancreas.com/3d/harrier/colours1.jpg

(not sure why) since it should look more like this:

Look forward to your comments.

Hi Shapeways team,

I have two issues with the latest couples of 3D print orders I have made.... which were a collection of men's rings.

1) I have ordered various different ring designs in stainless steel, Polished Bronze steel and matte black steel. Almost all of the rings were improperly cleaned. Small stones were sitting all ofer the products. A special pointy tool was required to move the stones. First of all many potential clients won't have such a pointy strong tool at hand which can remove the stones. 2nd the customers should not be asked to clean their products themselves. 3rd som stones are so hard to get out that one could be afraid to damage the product with the tool used for removing the stones. I would GLADLY pay an extra 1$ or even $2 to have the products properly cleaned. Shapeways prodly talks about (in the annual report) how many hands a product is passing until it reaches the buyer. However some of the last set of hands (and eyes) should make sure that the customer is receiving a quality product properly cleaned.

2) The stainless steel product I have received varies a LOT in colors. I have received some successful products that have the real stainles steel color... however many of the steel prints vary from quite yellow to normal stainless steel (NO yellow). What is the reason for the steel products to vary so much in color that you can never be sure if the product you receive is yellow or steel grey???

Mike

2. Steel it is infused with bronze and vary in color due that bronze ...

Many of the 3D prints I have received in steel (about 1/2 of them) looks like this when I receive them!

We are seriously talking about 1/2 the prints I have received looks like this... I can't expect a customer to receive a product like this and then they have to clean it. I would say some part of the EXIT team (before shipment team) seriously needs to quality control the cleaning to prevent this from happening. I can't understand how Shapeways can ship products like this. Then they should charge more money and then deliver a properly cleaned products. Nobody can run a shop if this is what the customers are receiving!

I work here
I'm sorry to hear this has happened.
Best thing to do is sending an email to service@shapeways.com they will be able to help you out. :-)

1)
Polishing media may get stuck in small engraved details and sharp corners

Steel products are tumbled with a corn polishing media to smooth out their surface. If your product has small engraved details or sharp corners, this polishing media may get stuck. To avoid this issue, make your engraved details over 2mm wide and avoid sharp corners.

2)
This material is 3D printed 420 Stainless Steel infused with bronze, and has a final composition of approximately 60% steel and 40% bronze. The way that bronze infiltrates into the steel can vary, and this changes the color of your product. If there is a higher concentration of Bronze near the surface of the product, it will take on more of Bronze's deep brown color. This has the most noticeable impact on Stainless Steel, but can also affect the shade of other finishes.

Hope this information helps!
Mitch


Kind regards,

Both problems are mentioned on the materials page for steel, but the color variation really REALLY needs pictures that show the expected range of variation (for both the plain infused material and the gray-to-black finish) , and the stuck polishing material looks a bit excessive. What is the dimension of the detail features trapping them ?

The details that are entrapping the polishing material is about 1,0 mm for most of my designs where this has happened. However one design had even quite more space in the details but still entrapping the polishing material. Since the designs are printable and has gone to final products I don't think it is fair to ask designers to change their designs to more rough details. It is fair to say it should leave the Shapeways factory completely cleaned... and then shapeways asking a few more bucks for cleaning properly. I'd be happe to pay more for products that I can sell with good knowledge that my customers are receiving a properly cleaned product. Otherwise they will think this Shapeways business is not serious business if they will have to clean the products themselves. This may go for true Shapies but not for the general customer that we shop owners wants to attract!

Work with it. Call it, The Ring Of The Earth! HAHA! :D

Nah, just kidding. Perhaps you can increase the clearance a little to make it less likely that the polishing media will become lodged. I don't think Shapeways does any cleaning of the polishing media. This has been a known issue for years.

If I were Shapeways I wouldn't use that polishing media. I'd use something a lot larger and with a consistent size. Then I'd use something like a 400 grit abrasive to do the cutting. Or if I wanted to stick with that media I would switch to centrifugal barrel polishing machines rather than vibratory machines since they would be less likely to pound the media into crevices.

Only now and nothing new, for anything new would add to the infinite, yet there can only be one infinite. Only one. The universe is only becoming something new in the delusion of our minds. This delusion that makes life worth living in our perceived universe becoming.

I had the same problem with some products I received yesterday. The cleaning wasn't really hard, I just used a sewing pin. I prefer to do it myself than to pay (indirectly) for manual labor of Shapeways employees.

I personally dropped Steel materials from my "jewellery" list and I`ll only use at the lowest , Raw Brass for rings that will look more antique / Polished brass for the whole precious family production.

Steel to me looks more for decorative arts , sculptures (that need manual polishing extensively and ever over paint ) , artistic door knobs ... other non "jewellery" stuff...

That it is the way I chose WSF Black Plastic as last resort material for fine things and prototyping . I rather have a failed WSF Black Plastic in my hand than ... a silver ring.

But that is I guess if you don't let your customers buy directly from Shapeways? Would you let your customers buy a non-cleaned product? Well as in any other matters there are individual opinions about this... BUT then I would appreciate if 'manual cleaning' was an option when buying!

The website 3D Printwise just interviewed me about Joy Complex and my other store 3D Racetracks! Check it out when you can! Hopefully this will help build some awareness of my track models in particular.

I would really like to get some traction with 3D Racetracks (no pun intended) so it would be wonderful if anyone who is will can share the story on facebook/twitter.google+. Next time you need some shares I'll be there for you!

If you're looking for a jewelry related story I can help you with a story about my shop.

On the other hand, I can also direct you to other jewelry related shops that could be of interest. Such as, numarul7, Laméris, Muse Inspiration, Joy Complex!, Peregrine Studios Artistry. Each of these jewelry related shops have creators who regularly post in the forums and are therefore likely to be easily approachable.

Thanks UniverseBecoming! The story just went up on 3D Printwise!

Good day all.

Well today I tried to upload some models of my new ring.
Besides the probably well known thin wall rejection galore, what mostly wonders me is....where did they go?
The thin wall issue is another story to tackle since all my programs like Nedfabb and Meshlab say all is good.

I did all the upload steps needed, put a price on it, assign materials etc and I got the needed e-mails telling me that I did upload them etc.
However they won't show up in my models folder.
If I follow the links in the e-mail's I get to the models and can change things however nothing under my models or in my shop.
Besides some older models I already had there.

Can some one tell me this is a bug or did I do something wrong or missed a step?

Any help would relieve me from some frustrations.

Thanks in advance.

Regards,
Jay

Hey all. I've been modeling and animating at a hobbyist level for years, using 3ds Max (and 3DStudio Max, and 3DStudio R4... etc...). I have finally decided to take the plunge with some 3D printing. I've already done a model and I'm waiting for it to arrive (very excited).

But next, I'm curious to try vehicles and action figures.

I'm interested in learning some techniques for modeling single print vehicles (best wheel assemblies/axles, etc), and for multi-part vehicles (best way to attach separate pieces, snap-on techniques, joints, etc). I'm also interested in action figures, ball-joint style or otherwise. I've seen some people doing figures with elastics inside. I haven't been successful in finding other people's workflows for this sorta thing and I'm curious to get some input before I get started modifying my models to this end.

I'm looking for fellow shapies' experience with the same sort of thing, tutorials, suggestions, debates, whatever.

A good bit of the "technique" you are asking about is entirely dependent upon which drawing program you use.
Three models I'm particularly proud of:
http://shpws.me/vkUd
http://shpws.me/u3ex
http://shpws.me/oumj
Check the video on the first two.

All three are printed in FUD as one single object.
My mantra for all such models is "one tenth of a millimeter". An axle that is 1mm in diameter needs to have 0.1mm clearance on ALL sides.. that means I have to make a hole that is 1.2mm (note: that obviously would have to be larger for other materials)

What I do most of the time is:
1) Place the axle (cylinder) where I want it to be.
2) Then I duplicate the cylinder in place, and make the copy 0.2mm larger in diameter.
3) Then I subtract that object from the "wall" that will support the axle - making the hole the axle goes into.

This way, I know the hole is centered around the axle.
The "trap" with this method is not to "bump" the axle later and knock it out of position - unfortunately, that happens a fair amount to me. If you get the axle out of position relative to the hole, then you're likely to have the axle and the wall become one unmovable object.

What takes some understanding is that you must have the "one tenth millimeter" on ALL SIDES... it is too easy to get lost and think that you've got enough clearance around the circumference, and forget that you have the two flat bearing surfaces touching.


Patience, Persistance, Politeness - the 3Ps will help us get us to Perfect Printed Products

Really impressive detail on those! They're tiny yet functional.

Did you basically model a tab on the other side of the axle that keeps the whole assembly from sliding out, or is the "tab" basically the wheel on the other side?

Really impressed by the scale of those things.

Have you worked at all with bits that need to be assembled after printing?

Is anyone else noticing a much longer lead time with the WSF materials polished and unpolished. I used to have orders start printing in a matter of a day or two after placing the order. Now it seems its almost a week before stuff even starts printing.
