UDP printing rules…

I’ve read the UDP printing rules… Really?

I can’t print a complete ring or a bracelet? I’m missing something…

I can understand that we can’t print thicken o full filled sections, but I don’t understand that I can’t print a hollow cube, as example.

I’m wrong?

If you can explain it a bit better I will appreciate it…

Hi, can you post some pictures of the hollow cube? and the printing settings? If it’s hollow and airtight, it needs a vent to print it and the vent should close to the platform.

Hi again. Many thanks for your fast reply!

Please, see attached pic. This is why I’ve bought the Uniz, for printing model kits at high speed.

If I can’t use the UDP mode for print it, the Uniz is not useful for me.

You haven’t stated nothing about that very tight UDP printing rules in your campaign, so if is not possible to print what I need, I want a refund. This is not fair if I can only print open volumes…

We need to print what we need, no what the printer wants to/can print!!!

Please, correct me if I’m wrong.

Many thanks for your support!

What is the tallest dimension? Do you mind sending the STL file to support@uniz.com for us to try a print setting for you?

Hi again.

The tallest dimension -the nose cone on the image- is about 47 mm. I can send you the file but it must be deleted after use, please.

I’ve just sent an email to support with the STL file.

Waiting your answer!!!

Many thanks

Sure thing, we will work on it right away!

@Adam, just check my Shapeways 308 Bits shop under the Eagle 2999 tab… 😉

Tall enclosed structures would impose a complicated resin level effect and cause deteriorated inner surface and eventually damage the wall, causing thin walls or holes, this applies to all top-down continuous SLA technologies. For any enclosed structures, resin inside will be trapped since the strucutre wall forbid resin from flowing into or out of the wall. To build the walls continuously, UDP mode consumes resin from both inside and outside of the wall. The resin level inside will drop significantly faster than outside, and depletes quickly. Once depleted, the walls will be broken either by insufficient inside resin or by the pressure from outside resin (if the outside resin level is high). Solutions are: avoid fully enclosed structures, periodic release holes in the vertical direction, or vertical release slots. The SLTV do not have such issue because of the side exposure setup and the resin can flow through a top (side) hole to refill. We also applied for another patent to resolve the top-down resin level problem, but it will involve a compliated hardware add-on to the SLASH, and will not be available in the short term. Thanks.

On the other hand, rings and enclosed structures may be printed vertically with an opening on the side to let resin flow into and out of the structure.

Hi again.

I’m really upset about the UDP rules. I’ve purchased the printer for his speed… Now I will have a printer that prints like any other DLP. I’m feeling being stolen… You haven’t been fair at this point.

I need to print with UDP and you never told it during the campaign about the UDP printing restrictions. Knowing these restrictions I would never purchased the OL. If I need to print a ring and the printer can’t print a ring, it’s useless. The rings are closed… It’s really funny you saying that if we need to print a ring we must open it… Come on!!! The printer must print what I want…

With that rules it’s impossible to print nothing in UDP mode. I have hundreds of designs like the one I’ve sent to you, but none of them can be printed in UDP. 

I want a solution. I need the speed of the UDP mode for my models and parts.

Many thanks for your understanding, but I’m really upset…

You can send the models you want to print to our support, they will look into it and set all the printing settings for you.

Hi Antonio,

I just saw your issue and your shapeways. If you make the design by your own (with cad software), you could cut verticaly parts currently impossible to print with UDP.

Hi Cristophe.

Many thanks for your message. The problem is that I don’t have to cut vertically my designs. The printer must be able to print whatever in UDP mode.

I can’t cut my designs and I don’t have to cut them. I’m really upset…
