Hey guys,

First of all, Happy New Years! I hope you all had a great holiday period. My apologies for the delay in my response, I also had some time away from 3D Hubs and 3D printing because I was spending time with my loved ones.

I can tell this topic is quickly going into the direction which we feared already when we started this entire project. I can completely understand that these guidelines can come across as intimidating but please understand that they are not meant as such. The reason why we started this project to begin with is because me and my fellow admins came across orders where the quality of prints that were delivered to customers were far below what the average Hub prints creating a terrible experience for customer and giving FDM printing a bad name. The FDM guidelines have been created to set reasonable expectations for both Hubs and customers.

From the very start of this project we set out to create guidelines in co-operation with our Hubs. That's why I created this thread 2 months ago before any guidelines were created: https://www.3dhubs.com/talk/thread/fdm-hubs-i-need-your-input.

Afterwards, we created a first draft that we send out to a first selection of Hubs and asked them to give their feedback/suggestions directly on the Google Document we created. Once we took all their feedback we created the version that you see now in this thread. After a week I saw almost nothing but positive responses and we went ahead with the implementation of the guidelines which will go live in a couple of days.

Now, the main issue that I see is the topic of the dimensional accuracy. I am still completely open to suggestion on how we can formulate this differently. The guidelines are not set in stone and if we see something is not working as intended, we can change it. 

Please know that I am reading everything you guys have to say and I really appreciate all your input. I hope that I'm correct when I say that your concerns show me that you care about 3D Hubs and what happens to this platform.

If you have any additional concerns about 3D Hubs as a whole, you can always reach me through robin@3dhubs.com

Best,

Hey guys!

Thank you all for expressing your concerns and giving me your feedback. I really appreciate it. The reason that we have to set guidelines on dimensional accuracy is because we have to draw the line somewhere and we thought setting a 1 mm tolerance would be a reasonable first step. 

I completely agree with the fact that you, as Hubs, cannot know the application of your customer if they do not communicate it. Ofcourse in some cases you will have an idea by looking at the design that it's part of an assembly and in this case you can double check with your customer if a 1 mm tolerance is sufficient.

But in most cases this is not the case and also, not your responsibility. If you receive a model from a customer and you print it within the guidelines that we as 3D Hubs set, you will be paid out for the job no matter what.

When a customer is not happy because the print does not exactly fit, we will ask them to take a photograph of the print next to a measuring device such as a digital caliper to show the exact size of the print. Of course we do want to keep our customers happy but this is not always the responsibility of the Hubs.

Feel free to reach out to the 3D Hubs admins (such as myself) at any point if you have a situation where the customer is not happy with the result but you printed the part according to the guidelines, we'll definitely be able to help you resolve such a situation.

Best,
Robin - 3D Hubs

Hi @Boelle,

 

That's correct, the FDM Quality Guidelines will be the same for all FDM printers. We can't expect every customer to know what kind of quality they can expect from a specific printer model/brand so that's why these guidelines will set a standard for all FDM printers.

 

Best,

That's exactly right, these guidelines are set to that both Hub and customer have default expectations of a 3D print. If a customer needs the parts with higher dimensional accuracy, it should be indicated and this is what we'll add during the order flow so customers are aware of what they can expect.

Hi @Pepstick, the images are still in progress. We're currently printing the same part again and again to show different print qualities, which are acceptable and which are not. The picture in my comment was just a quick snapshot I took with my phone while printing.

Hi @cobnut, thank you for your reply. We definitely realize that the surface area's connected to support material can never be as continuous as a top layer or the ones directly on the bed. That's why we mentioned: "Small traces of support material are often unavoidable and acceptable (see image)".

 

We'll also take a precise photographs of a part printed with with support and how it should look after it's been removed. Here's a preview of the part being printed at 3D Hubs.

If it's important that a complex part has a similar surface finish both on the top as well as on the bottom (support) side, we highly recommend that you inform your customer that they should expect this in the final print. Alternatively, they should be guided to another 3D printing method such as SLS which requires no support material.
 

I hope this gives a good answer to the problem.

Hi @N3DS

 

Printing weapons is a not allowed through 3D Hubs. We are a peace-loving company founded in the Netherlands and we adhere to strict Dutch legislation on weapons and fake weapons, and therefore we don’t allow it. Printing weapons violates Section 6.2 of the 3D Hubs Terms of Use.

When it comes to cosplay, we only allow weapons that do not resemble any real guns and cannot be mistaken for a real gun/weapon.

 

I hope this answers your question. Please feel free to reach out to me through support+robin@3dhubs.com if you have any more questions regarding the Weapons Policy.

Best,
Robin - 3D Hubs

Thanks for that Chris, very impressive order. I checked it out, that's a looot of pieces! After every order we do invite customers by e-mail to leave a review for the order and they get a reminder automatically if they do not. If you want I could send a separate message to your customer as well but in some cases, customers simply don't leave review.

Having a badge called "Blood, sweat and tears, this hub goes beyond the call of duty with their order" is actually not a bad suggestion. The execution would be a bit different but another way of standing out for Hubs that are able to print very high quality FDM prints besides just completing the Marvin review might be another way to go. What do you think?
