The TrysorTops 2.0 is a redesign of a previous spinning top so it can now be 3D printed in metals. The extra weight really keeps this thing spinning!

Shapeways is getting lost in their organisation or seems to do not take the designers and its own 3D print business very serious.


There MUST be done something on the process of designer to product, just simple steps which are known at any other design manufacturing process

1: The designer delivers and describes his design.

2: A print-checker must have direct contact with the designer when he print something for the first time. He gives with his best insight and intention what he thinks of it and gives advise with isseus about details.

3: The designer gives response and agree or not agree to print the model.

4: When something is printed with satisfaction, the designer must be able to click the button 'product ready for selling to customers'



$

This is how it is more traditionally done, but it is also quite expensive. When I do design consulting I charge upwards of $100/hr for providing advice on making things more easily manufactureable. I can easily see this sort of thing taking more than 30 minutes per design. Someone is going to need to pay for that. Not many people are going to want to pay this for a model that they likely will sell less than 10 of.

I'm not an expert on statistics or stochastic processes but I'm not sure Shapeways is either. There's a lot of weirdness in print failure thresholds. This is especially apparent for new designs. I can have the same new design printed in WSF and PWSF with the PWSF giving 100% print yield and plain WSF having 67% yield. That seems odd since the PWSF should have more problems because of polishing stresses. And statistically speaking, how many print attempts must be made to accurately reflect all of the random processes in the production flow over time? Five separate prints? 10 separate prints? All it takes is one day of poor quality sintering in a machine or a confluence of abnormal operator events that leads to breakage and your design could become toast in the print success column for a particular material. And lots of people have mentioned failures/rejections happening after a long periods of success. It makes me think the success rate numbers are not a proper gauge of the production processes, or that some of the.production processes are not well controlled.

I've had models that upon upload check out across numerous materials then when I revisit the model later is only available in WSF and black WSF. I'd attribute failure rates to buggy calculations as much as physical breakage, if not more when it comes to products that break even after the software checks are clear across the board.

Another issue in physical breakage may be due to orientation. A cylindrical wire oriented vertically may print fine but in another orientation will be stepped along the curve, which has a tendency to weaken the structure with all the cut ins along the surface that result from stepping. This is just one more reason, on top of quality control and consistency, that I think designers should be able to decide orientation. We've been given a myriad of design guidelines to follow for clearances, minimal wall and wire thicknesses, etc. Why is orientation not a choice we're afforded as well? Is Shapeways more concerned with efficient packing and saving a few dimes here and there than they are with being able to offer a consistent quality of product? It seems to me they'd be losing more money on reprints, as well as customers from rejections, than they're saving by taking away our choice in the matter of orientation.

It all depends on your design software, since different packages interpret "up" in different ways. When you export to STL format for uploading to Shapeways, whatever axis your package thinks is "up" becomes the Z axis. In AutoCAD I can create several different coordinate systems in a drawing, so can pick the one where "up" is Z - then the models upload correctly in Shapeways.

Bear in mind your choice of "up" ONLY affects the render that folks see when they shop, because the techs at SW will orient your model whichever way they need to to fill a space in a build tray!

Although I doubt there's a single designer out there that wouldn't love to have the option to set their own orientation, both on the render and in the print.

I am working on a tabletop game that uses these pieces. I have 11 gladiators and 18 arsenal pieces ready. My favorite part is that we were able to redesign the pedestals so that we can print legible character stats directly on there! Pretty fun.

Credit goes to SpecToys for much of the heavy lifting.

I am looking forward to getting the other 9 because a lot of them had more detailed armor/weapons/etc.

I got my prototype of my 8th Doctor's sonic screwdriver model kit today and had a chance to clean it up and put it together, showing the implementation of an existing electronics core unit to get light and sound using the functional trigger on the outside of the main shaft of the prop.

https://www.youtube.com/watch?v=GTUyBdYfcfk

You can see me struggling to insert the core unit inside - some increase in tolerances are in order there, but I managed to squeeze it in for the demonstration.

The trigger is extremely responsive to activate the push button on the core, which I'm extremely happy with, as this is the most important function of the kit's new design features.

The FUD emitter head doesn't light up as much as I'd like (a result of the core unit and its relative position to the trigger on the actual prop leaving the LED a good distance away from it) so I grabbed a piece of 1/8" acrylic rod I had on hand to place in front of the LED and extend up into the emitter itself. I sanded the end and outside of the rod to diffuse the light and once implemented, you can see an increase in the brightness of the actual emitter. I've since ordered a 3/16" thick rod and redesigned the inside of the top 'fin assembly' to hold it in place. This should go a long way to light the emitter properly.

There is significant light bleed through the white plastic around the location of the emitter in the core but after one coat of black paint, it's significantly diminished and should be gone entirely after a few more coats of paint (except maybe in the dark).

index.php?t=getfile&id=86010&private=0

At the end of the video, you can see me comparing it to (what's left of) the old version of the model which was much smaller, and to the 11th/12th Doctor's sonic screwdriver 3d printed (and painted) prop I designed awhile back. At the very end, you can get a better look at the emitter brightness when I turn the desk lamp off.

I'm really happy with the way the pieces turned out, especially with the responsive functionality of the trigger. It's easier to activate it with the trigger on the model than with the push button itself! Aside from an oversight on my end involving the necessary clearance inside for core, everything fit's nicely. That emitter clicks right into place, you can hear it! It's just a but difficult to remove...

What software are you using to create the model and what format are you uploading? These may be relevant to the problem and help the support team zero in on the issue.

Works for me (at least with a smallish stl file that I keep around for this purpose). Make sure that your file is smaller than 64mb (zip it if necessary) and does not contain more than about 1 million triangles.

Disregard my previous post, I failed to see that you did mention that it was an STL file.

Out of curiosity though, I attempted to upload a file I know to be over a million polygons and was brought to this link:

https://www.shapeways.com/upload

When it brought me there, I saw an error message, so I copied and pasted the URL into a new window and it redirected me to https://www.shapeways.com/create. If you try clicking that '/upload' link above, it will also redirect you to the same '/create' page. It's possible that your browser automatically refreshed the page during the upload, or when it failed, and you were redirected as a result.

On a side note not entirely unrelated, when I tried to upload it again so I could screen grab the error message, the model successfully uploaded lol. I guess if you're persistent enough, it ignores the 1 million polygon limit. This may be another bug...

I think a staff member wrote recently in some other thread that the internal limit had been raised to 1.5 million - also note that increased complexity may mean increased processing time, i.e. the initial checking is more likely to time out, and also any automatic fixes may increase the triangle count beyond the limit if you are unlucky. This is why I wrote "about 1million" triangles.

Being able to segregate classes of files outside of the mainstream store files would be helpful. It would make it much easier to focus on store items until others are ready for sale, or to group files by custom work orders as mentioned above. To some extent you can do this with the filtering (private, public, for sale, not for sale) but that still means one long directory. Having a folder file structure would be awesome.

I've seen a couple of issues raised by people offering ShapeJS customized products. It's my understanding that these designs appear in the same product directory as everything else. You should be able to create a folder for let's say a customized cell phone case for an iPhone and another folder for a customized HTC One phone to keep them separate. That's especially important if you also offer other designs. One work around to this is to open different stores for different classes of designs, but really? That's also a big hassle. Maybe one partial solution is to be able to tie one log in to different stores, sort of like aliased email addresses, therefore treating the various stores as a folder file structure.

Since my Thread in General Diskussion has been deleted or moved or sth.

I would mouch appriciate a different delivery service for Europe as well. At the moment I pay 10 Euros for a 10 Euro Item...It is really hard to get only one model iteration. You literally always have to order in bulk. It is a little bit anyoing. DHL should be a good option aswell.

But just my 2c on the UPS pricing situation.

Aside from FUD, I've only ever printed in WSF and polished WSF but was looking into printing in WSF black for a current project since the prop I'm building will have lights and I want to prevent light bleed through the plastic. A few good base coats of black paint usually does the trick but I was curious if printing in black dyed plastic is a suitable alternative for a few dollars more.

My first concern is something I read elsewhere on the forum about issues with models not being cleaned well enough and powder left in crevices of the model before dying, resulting in exposure of the white plastic beneath these areas once the powder is cleaned post-print. Has this issue been resolved by any change in how they dye or is the fate of the dye quality still left in the hand of those that clean the parts manually and may not care enough to do it well?

Second, has anyone printed functional parts using any of the dyed plastics and noticed changes in tolerances between parts as a result? I knw I've seen some puzzled printed in WSF black and I'm sure they would need the most precise joints in their complicated models, so I figure if they can do it with those complex forms, I can do it with my 15 piece model kit that needs to fit together a certain way - would I have to adjust some dimensions to compensate for any change in how they'll fit post-dying or does the dye not affect the tolerances that much.

My model doesn't pass the guidelines for printing in black detail so that's not an option either.

I may be wrong but I thought black wasn't dyed, I thought it was a black powder?

Also I think you might be referring to one of my prints in regards to the powder getting stuck, in particular this thread.

I think there was something other root problem at work that caused the issues, the replacement I received only has powder in deep holes which fine by me as I use those as connectors so they won't be at all visible.

Also it depends on how much build up there is, if there isn't a lot the color might still have seeped deep enough to properly color the surface of the model under the built up powder.

As far as the tolerances go, I think the only major difference would be the polishing, plain WSF/BSF don't get any polishing, Any of the dyed WSF gets some polishing while the plain PSWF gets the most polishing. Even then it shouldn't account for too much, especially given that depending on the size of the connection points the polishing medium might not even be able to work their way into the smaller areas at all. Now when designing parts and layout them out for sprue-ing I keep that in mind to ensure areas that need polishing are as open as they can be while I save space by using areas that not need polishing (the underside of feet for example) close together.

It was this thread where the issue was with black WSF in particular, in which the part was apparently dyed without a proper cleaning first and the dye wasn't all the way through to the surface of the actual print. The OP there also thought it was a black powder or something similar, I assume, but it turns out it was only a coating of sorts that powder residue inside recesses prevented from affecting the surface properly - similar to your case, it would seem.

I also notice your parts are polished, which I generally avoid on account of a previous experience where I ordered polished and adjusted tolerances accordingly so my second round of prototypes fit perfectly, then when I put in the full order, the polish treatment apparently had changed and everything fit very loosely.

I'm wondering if the dying process on the black WSF has a similar effect.

No, it is dyed, just not polished. While EOS does offer a "black" PA2200 for their printers, shapeways presumably does not want to dedicate a printer to this material, (or the material properties are inferior to WSF).
Amount of residual powder will certainly depend on the geometry of the part, also I guess some may adhere due to electrostatic charges or may even be lightly fused to the surface, detaching only after repeated mechanical stress.

Well that's all I needed to hear! It's not worth the risk just to avoid an extra coat of paint or two. One of my customers was asking about it so I decided to look into the option but it just doesn't sound feasible for a function model with multiple connecting or moving parts.

Although I do recall seeing some of Oskar's puzzles printed in color S&F plastics - or maybe those were DIY post-print dye jobs.
