STL export is NOT printable

Hi Me as the CEO of a biomedical engineering compsny active in the field of patient-specific implants, and my staff are loving Umake, but there is a very critical problem, hurts, SO MUCH, that is, the STL export of the app is NOT printable in any 3D-printer, and the company needs the 3D print option as a MUST. Looking for your support pls. Best

STL above, is misregarded, the right one is the OBJ format

Hello, 


Thanks for sending this in and writing to us! We are really happy to hear about how you are using uMake and it's very cool to hear your staff is loving the App. 


We are aware that the exported files (OBJ, STP and IGES) are not easily printable directly from uMake itself, this is inherent when modeling with NURBS as you are creating individual surfaces, versus working with solid, closed parts which you would get with polygonal or solid modeling. 


NURBS modeling gives you more freedom to model more organic shapes, but in order to make models crated with NURBS printable, there is usually some work that needs to be done before sending the models to a printer. 


We have successfully printed files initially created in uMake by way of importing the exported uMake files into Rhino, then creating 'watertight' parts (closed volumes) and then exporting that file as an STL from Rhino. 


Depending on the model this can be a relatively straightforward process, or it can require some work. It really depends on the model. Do you have an software that you can work with uMake files prior to sending them to the printer?


We are aware of the demand to be able to print models created in uMake and have this as something we want to address in the future. I hope that helps but let us know if we can be of any further help. We are really excited about your use case so we would love to see how we could support this effort. 



Thanks so much, i was waiting to hear from you since the App. is almost an everyday-used program in our company. I heard about Rhino but i dont know whether it could be installed on my ipad or not. Best.

Really cool to hear you are using the app on a daily basis. Rhino works only on computers (it is cross platform, mac and PC and works great with uMake files (especially IGES/ STEP). It's also relatively easy to learn and since it has been around for many many years there is quite a bit of support behind it.  


I'll contact you and see if we can set up a call so we can help further. 


 

Hi,

I am glad that I found this thread using a Google Search. I too love UMake  I have printed some items that come out correctly even though the model looks like it is not going to print correctly and others not so good. I am starting with simple designs. I use Simplify3D to convert the STL file to printer gcode. I downloaded the app Meshlab that I am just starting to learn. I just downloaded Rhino (suggested here) to also try out. I hope one of these will solve our issues. Also I have the issue with how I orient the opject in Simplify 3D. If I print the object on end it prints ok as regarding to not filling in the cylinder part infill. But if I lay the part flat on the build surface Simplify 3D will want to fill in the holes like I wanted a completely solid object among other issues.

Thanks John but we’ve moved to Shapr3D since about 2 years ago. It’s a very matured and reliable iPad-based app, doesn’t need any other softwares you mentioned, and also it has WOWcapabilities(!) compared to uMake. 

I wish uMake team best of luck.
