Porsche giving away Cayman STL


#5

Hi David, I also “Decimated” the STL in zBrush which has done a much better job than Blender. Also I scaled it down to fit in the 125mm print space for the Form1…and by the way…I am a Porsche guy!..just don’t own one yet hehe.  https://www.dropbox.com/sh/rc3duuihvwo51ds/X_30EBkn4O

Agreed. The Blender decimate was HORRIBLE. It left a choppy surface, even though there were still oodles of triangles in the mesh.

I smell a feature request for the next gen PreForm!


#7

I don’t understand why you guys had to decimate the Porsche STL? It opened fine for me in PreForm, its just scaled down to .029. I don’t have a printer yet so does the file size cause some other issue with printing?


#8

Hey Vince, I just don’t feel that the mesh was very well optimized that’s all. Decimation keeps the detail where it’s needed.


#9

Hey guys, I saw this model and had to give it a go.  I printed the lower resolution model (that David posted) at 100 microns in the new white resin.  The print took about 5.5 hours and came out great!  The car is about 5 inches long from bumper to bumper.


#10

Finished printing last night.  My first try failed because I made the supports and points too thin and it pulled away.  This one is in 50 microns because I was impatient. Printed at .017 scale.


#11

Wow Adam that looks great at 100 Microns!  And that new White is really nice looking.  Going to have to place an order!


#12

Dylan, your print looks great too!  Super smooth at 50um.


#13

I tried to load the file into Preform and it crashed on me. The file they gave was needlessly large, I’ve tried it in a couple slicing programs too and they got bogged down.

I wish Porsche had put the wheels & tires into separate files.


#14

Hey Jeff, why don’t you try the optimized versions by David or myself?


#15

Hm, what platform are you on, Jeff? It’s definitely slow and bloated, but I loaded it up and printed it, no problem, on my machine (Macbook Air, 8GB).


#16

2011 iMac, quad core i7, 24GB RAM, latest version of PreForm. I’ll give it another try. I downloaded, but didn’t try the reduced files here.

It’s just that the file is 10x larger than I’ve ever needed to use, including other car models that I thought were plenty high quality, so Porsche’s offering seemed unnecessary.


#17

I think you might need some more RAM Jeff : )


#18

Second try seemed to load better.


#19

In all seriousness, I really could use some more RAM. I don’t have to have it, so I’ve been putting it off, but I’m running down to 400MB free.

I don’t know what happened before.

Anyway, is there a good way to hollow out the underside of the model? It’s a solid car. Even at only 1/64th scale, it takes 22ml of resin, before factoring in supports.


#20

Yah, the model is totally oversize – no doubt about it. I just want to get to the bottom of the issue’s your seeing – yep, what Jesse said. You definitely need more ram :slight_smile:


#21

Hi guys!

I just stumbled over this thread, but unfortunately the original file(s) is not available anymore. I did download the adapted versions by Jesse, but if anyone has the original available for me to play with, I’d be very grateful!

Thanks!


#22

I just tried to but its like 93 MB & there’s a 20mb limit, I could try to email it to you?


#23

E-mailing would be certainly acceptable, otherwise using Dropbox, Google Drive or wetransfer,com would work for me as well.

My email address is: avdleeuw (the at sign) gmail (the dot thingy) com

Thanks in advance!!

no prob, its on the way!
