Hi Thomas,

I'm glad to see SW is looking at its policy. Hopefully you will come to something rather more sensible than the arbitrary size cut-off that is currently only sporadically enforced judging by all the nasty weapon-like models that are available to order. I assume we're not looking at some kind of company "morality" policy here, and are instead concerned with avoiding becoming back-door arms-dealers?

There is a significant hobby of scale-modelling that involves miniatures of "weapons" in scales like 1:72, 1:35, and even 1:6 (Action Man/GI Joe), and these are clearly not "replicas" in the sense of something a sane human could mistake for the real thing. The current policy with its arbitrary cut-off at 10cm seems to discriminate against models of large items (say a 1:72 railway gun whose barrel is nearer 20cm long, or GI Joe's 8"-long rifle) while allowing rather nasty 1:1 scale knives in the sub-10cm size to slip through. (Prison "shanks" made from toothbrush handles aren't very big, but are still lethal!) SW needs to look long and hard at the true intent of their policy, and refine it to allow larger "scale models" that are clearly not functional as real-world weapons or even as look-alike dummies. Then, it needs to truly crack down on models that can be dangerous in the hands of nasty 1:1 scale humans even if they are not marketed as weapons. After all, it is distinctly possible to design a functioning handgun from 3D-printed parts that are each under the 10cm limit, but somehow the SW "safety net" is preoccupied with scale models of field howitzers.

If SW continues on its current arbitrary length policy they will only succeed in driving the scale-modelling fraternity into the hands of competitors like C2D, who are sensible enough to know the difference between a hawk and a handsaw...

Hi people

Im in the process of having a few components 3d printed.All the components are from white plastic.

Can anyone suggest a glue,that would be best for attaching these together? It will be a display item only, so no load will be applied to it.


Thanks in advance for any help!

Super Glue works just fine in my experience, you just have to keep in mind that because WSF is a rather porous material so you will probably need to use more glue to ensure a good bond as some of it will seep deeper into the parts.

Ok, it now works. Also SW solved problem with updating markup for items already in shop https://www.shapeways.com/forum/index.php?t=msg&th=28240 &start=0&. Nice work. But...

Here http://shpws.me/JcFB I see that rendes not changed for some materials (but it's done in model settings). I hope that all will works fine soon.

We've found the reason for images acting up on some models. We're working on a solution.

Hey All,

I'm excited to share a little preview of some changes we're making to the Community homepage.

Currently we have a page that tells you how to get involved in the community but static. that isn't very useful after you've seen it once.

Our amazing design team is working to bring this page to life with new dynamic content. You'll be able to see the most active forum threads and sections along with upcoming events and news about the community.

index.php?t=getfile&id=109771&private=0

This is still a work in progress so if you have ideas or suggestions let us know!

Hey everyone. I have bee selling some of my 3d models in the virtual world and would really love to see some of them in my own hands but I have no Idea how to start. All of my models have been scaled by eye to match a player character. It]s easy to just eyeball it and position the stuff around the character when it's for the virtual world. How do we scale things for shapeways? Some of my models like the one in my picture have clipping vertex groups and I don't understand how the printing machines would deal with that. Is it safe to assume I can't use this method? I am also curious if I can print using 2 kinds of materials. If these questions are are covered already please point me in the right direction. Thank you. <3

Not sure I understand the question about scaling, or at least I do not see the specific relevance to 3d printing ? The vertex clipping would hopefully be taken into account by your modeling software when you export to one of the commonly supported 3d file formats such as STL, OBJ, DAE or WRL/X3D. I expect if problems will arise it will be from subtle flaws that do not matter for a purely visual representation - coincident surfaces, tiny holes, sheets (like a character's cape) that have zero thickness. Familiarize yourself with the 3d output options (and perhaps even printability checks) available in your software (which is it ?), eventually download the free, cross-platform netfabb studio basic software from netfabb.com that lets you check for and fix some of the most common problems.

Printing in two or more materials is not currently possible, unless you can split your model into separate parts that you or your customers can assemble after printing. Multicolor printing is possible in a rather heavy, brittle material shapeways calls "full color sandstone" - actually gypsum powder held together by superglue and colored with a low resolution inkjet printhead. Trials are currently underway for a similar process using plastics particles instead of the gypsum, and an even more advanced printer type has been promised to become available later this year.

All the information about costs and required dimensions are contained under the "Materials" tab at the top of the page, you may want to view some of the production videos in shapeways' youtube channel to see how the actual printing is done and what level of manual work is still involved.

Thanks for your reply, I have watched some videos on the process it goes through and the video on tiny empires. I'll look at the others when I have more time. My question on scaling is the one I am most concerned about. I use blender and I'm sure it has a ruler function but I have never used it.
Scaling has to be exact in the real world. If I want something to be the size of a golf ball it has to come out to 1.68 inches. How do I make that possible?

Choice of orientation: Yes please. ASAP.

FUD and FXD for me.

For the reasons already stated in previous posts.

But mainly CONSISTENCY!

Being able to choose the print orientation is THE one feature that has been missing from shapeways as the orientation a model is printed in, especially when using FUD, is critical and seriously affects the quality of the final model.

I have a number of models that I'd love to put on sale but I can't as the quality of my test prints have varied so much due to print orientation issues. What is so annoying isn't so much that we can't choose the orientation (although that would solve the problem) but the complete lack of consistency. For example, in the past I've ordered multiple copies of the same model, in the same order, only to find some are perfect while some are useless due to the different print orientations. In fairness when I've complained I've usually been given a refund for the useless prints; i.e. print orientation issues cost you money. As I have an understanding of the print process I try and design my models so that when printed, in an orientation to minimize support material, they will be at their best. This means when you mess them up not only are they useless but you have spent more to print them as you've usually ended up using an awful lot of support material (most of the models are "bathtub" like so they end up full of wax if printed in some odd orientation).

In an ideal world I'd like the option to choose the print orientation; i.e. a drop down that allows me to choose which axis of my model should be orientated vertically during printing. This would be nice and easy to implement in the interface and should be easy to enforce during tray layout as well. I don't need anything more fine grained than that as I could do any other orientation inside the modelling software I use. I'd also be happy with this being an advanced option where I override your decisions but accept that if the print isn't acceptable then it's on me -- a bit like "print it anyway".

A compromise, which I've suggested in a few threads before, would be for you to algorithmically set the print orientation. Basically have the computer decided which of X, Y, or Z should be vertical to minimize the support material required (as this is what damages the surface). This would then mean that a single model was always printed in the same orientation removing, what is at the moment a lottery, and guaranteeing that multiple prints of a single model would be as close to identical as possible. You could then show that orientation in the 3D tools screen. Knowing the orientation in advance would then allow modellers to decide if they wanted to tweak the design to take the orientation into account.

Thanks for looking into this, and please make it a priority. It's all very good adding new features like the scaling tools etc. but if we can't rely on the prints to be usable then the funky tools are a waste,

Mark

Well done Mark, Nicely put.

Actually, as this subject is important to me I'm going to expand on my previous post, and state some specific reasons why orientation is important to me.

I design wooden bodied railway rolling stock in 1/152 scale. I really need the "print lines" to run along the planks / grain rather than across them. This makes the difference between a model that is good to go and one that needs a lot of work cleaning up. As Mark said above, If you are putting your name to a product and expecting other people to purchase that product, then consistency is essential.

Also there is the issue of the effect caused by the support material. Impossible to design a model to minimise this effect if you don't know which way up the model is going to be printed.

I have only recently made my models available for sale with the advent of FXD, having been thoroughly disappointed with the random results gained with FUD when I first started using Shapeways a couple of years ago.

Things have definitely got better, but there's still room for more improvement. Choice of orientation of print would be a huge step in the right direction.

Cheers,

Eddie.

> Do you want control over orientation?

Not really, for number of reasons:-

  • Any curved surface is likely to have stepping, what ever the orientation.

  • Printing a box in FUD or FXD gives one OK surface and five that will need work to get an acceptable finish so orientation is largely irrelevant.

  • Except in special circumstances, the costs and the amount of finishing required make printed items unsuitable for the majority of my potential customers. The effect of this is that I have come to the conclusion that printing is only really suitable for making patterns.


Of course if Shapeways were to offer a service by which FUD and FXD was given a shot blasted finish, I could very well be interested.

Controversial, for sure. And indefensible, in my opinion. Or at the very least, of arguable validity. Perhaps you are merely trolling.

Seems to me that your argument is based solely on legal, or pseudo-legal, arguments.

I say "pseudo-legal" because even a cursory investigation of common law yields statements such as the one in wikipedia that

"In some jurisdictions, criminal "facilitation" laws do not require that the primary crime be actually committed as a prerequisite for criminal liability. These include state statutes making it a crime to "provide" a person with "means or opportunity" to commit a crime, "believing it probable that he is rendering aid to a person who intends to commit a crime."

Regardless of the legalities, I applaud Shapeways for taking a stand which takes into account moral and cultural norms which inform all our lives with values which extend far beyond mere legality.

Thank you Shapeways!

This redneck rant about firearms production appears to be totally besides the point. The problem as I see it is that shapeways' current policy goes beyond the requirements of applicable law as at least its most recent interpretation as exemplified in the other thread appears to subsume even scale models of heavy military equipment into the "weapons" category.
While that is certainly defensible as a pacifist stance, it seems to be a poorly communicated business move that may cause grief to many shop owners whose larger models of historic fighter aircraft or warships may face a new kind of individual "rejection" on a case by case basis.
(While I am not personally affected by this particular move, it introduces a new form of unpredictability into shapeways' actions that I feel is highly detrimental)

Having looked at the other thread, I'm not sure this one adds anything useful to the proceedings. (If anything, it dissipates the potential impact of the other thread, squandering a chance to have meaningful impact on developing SW policy...)

Thanks for starting up this discussion James, we know that this is a serious issue and everyone is entitled to their opinion on it.

The other thread was a discussion specifically relating to one model, so I'm happy to see this more general discussion of our content policy move into another thread.

Your feelings on the subject are always helpful as we look at improvements we can make to the standing policy. barkingdigger, if there's anything you'd like to add feel free, this isn't going to squander your chance to weigh in on our content policy.

Even the TSA is inconsistent in what they allow through airports over time. Policy and bureaucracy are the result of limited resources dealing with large volumes of things that need to be examined by matching them to all sorts of rules. At one extreme there's the "print anything you want" policy and at the other extreme there's the "pay us an examination fee to maybe permit your part for sale after we clear it with law enforcement and our lawyers" - and we won't refund your examination fee. The in-between squishy zone is where inconsistency and irrationality rules because anyone who enforces rules tends to want to keep their job will almost always err on the more limiting side of things. And even one person is inconsistent over time in the decisions they make. It's a tough problem.

Having said that. is it ok to make accessories for guns for personal use? Items like adapter brackets for lasers or gun sights? Custom gun hand grip attachments or holsters? In other words items that are not weapons but are commonly sold over the counter (potentially to an 8 year old) and which may be transported anywhere without special government permit cards? I'm just wondering where the line might ultimately get drawn.
