Did you print T-Rex Skull?

GIFT3D · 2016-03-30T09:52:19.000Z

Hi again,

I just want to say that the hollow inside of the skull is rather hard to remove the supports from. Good luck with the end result.

GIFT3D · 2016-03-30T09:55:35.000Z

I just want to say well done to all those who printed the T-Rex skulls. They all look amazing!

BIBO3Dtech · 2016-03-31T00:17:01.000Z

Thanks so much for your support Can you show me your T-Rex skulls under support? Thanks in advance.

GIFT3D · 2016-03-31T05:50:09.000Z

Unfortunately I have already removed the supports so cannot take a picture with them on. Apologies

BIBO3Dtech · 2016-03-31T05:59:22.000Z

Hello GIFT3D, it is ok. Thanks so much for your reply and support:) Have a good day!

GIFT3D · 2016-03-31T07:09:34.000Z

I’m glad I could help. You have a good day too. Good luck 3D printing

Needs a bit of finishing work before painting, we’ll post a finished pic when done. Exam season, so might be a little bit. No supports 100 microns ColorFabb Standard White

Wow, looks amazing. What is this printed size? Good luck to your exam:)

UVic_3D · 2016-04-02T01:15:34.000Z

We printed at the original model size. That being said, it turned out really good, so I’m going to do another one at 125% or maybe even 175% when I order more filament.

Probably going to print it with glow in the dark filament

I’m hoping to have it painted this weekend, if I do, I’ll post another photo:)

Thanks!

BIBO3Dtech · 2016-04-02T01:22:58.000Z

It is really awesome. Can you give me more picture of jaw and teeth? Glow filament sounds interesting. Waiting for your updates!

UVic_3D · 2016-04-02T04:29:20.000Z

I’ll take some pictures tomorrow morning before I start painting for you. I printed it really slow because I was worried about the teeth to be honest. Still needed finishing work, but it definitely was worth the extra time to print in my opinion.

I’ll take and upload the photos tomorrow, gotta hit the books for the rest of the night

Beautiful model. I think I’m jealous. I should stop by the lab more often and peer in the window to see what is printing.

UVic_3D · 2016-04-03T02:20:39.000Z

Sorry man, didn’t have time today to get to it. I’ll do my best to get you some pics tomorrow morning before I start studying.

UVic_3D · 2016-04-03T02:23:27.000Z

Thanks!

We actually printed this at home. Unfortunately, the school has a really limited access policy to the printers, and we were not allowed access simply because we are civil engineering students… Politics…

We ended up biting the bullet and buying an Ultimaker 2 Extended. Once the upgrade kit came out we bought that, and now were off and running

UVic_3D · 2016-04-04T05:22:39.000Z

Hey Bud,

Here is a few pictures my room mate just took. The model is pretty much ready for paint now, which I’m going to try and do over the course of the next few days. I’m an amateur when it comes to painting, so I’m going to try and take my time. Hopefully these photos are what you were wanting. We have more from other angles, but I just picked the ones showing the lower jaw.

Cheers!

Tim

Hi Tim,

What machine was that printed on, it looks great!

Hi Dave,

Thanks!

It was printed on an Ultimaker 2+ Extended.

BIBO3Dtech · 2016-04-05T00:37:01.000Z

Hello Tim, sorry to reply you late. Thanks so much for your sharings. These pictures look awesome. Could you please tell me which settings you use? Thanks in advance:) Have a good day!

UVic_3D · 2016-04-05T03:31:40.000Z

We just printed it really slow, I think at 20 mm/s, with a slow travel speed as well to be safe. Also lowered the temperature of the hot end, but that’s more a filament/machine combination specific kind of thing.

I’ve done loads of reading on the topic, and the consensus is always the same for quality prints. Low print speeds, and lower the temp as much as you can of the hot end.

Have you done an extruder temp test? There’s a temperature test on thingaverse you can download. I had to manually alter the g-code to change the temperatures at different layers, but honestly its very simple to do. Then I ran the test, and I got a really solid idea of what the best temperature was for the filament I was using with the desired print speed. It’s totally worth doing if you have not done one. Gives you a base line to start from.

Cheers,

BIBO3Dtech · 2016-04-05T05:04:14.000Z

Yes, when we print T-Rex without support, the extruder temp is at 180C, the travel speed is at 50mm/s and layer height is at 0.1mm. Slower speed usually brings better results compared to higher speed. Different filament has different temps. Agreed. There is definitely necessary to do temp tests for good printing results.

Thanks again for your suggestions and your sharings.
