Did you print T-Rex Skull?

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

[GIFT3D]

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]

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]

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

[UVic_3D]

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]

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]

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

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!

Hi Tim,

What machine was that printed on, it looks great!

Hi Dave,

Thanks!

It was printed on an Ultimaker 2+ Extended.

[BIBO3Dtech]

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]

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]

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.

No problem, sorry I couldn’t remember all of the settings for the T-Rex print, but here is two quick pics of a print that just completed. Please keep in mind this is fresh off the printer, and literally nothing has been done other than removing the supports (not very well at that).

The settings were,

print speed 20 mm/s

travel speed 100 mm/s

density 20%

0.8mm shells

0.8mm top/bottom

100 Microns

ColorFabb Grey-Blue

Temp @ 200 (ColorFabb seems to need hotter temps, at least from my experience)

Full supports, otherwise it would have been impossible (at least for my printer).

On that note, I’m never using Cura again for supports. Virtually all of the supports failed, but I let it keep printing because I was convinced as long as the supports on the helmet worked the print should work out after a bit of sanding. Thankfully, those supports did work, and the print finished. Granted, a fair bit more finishing work is required, but all in all it turned out pretty nice.

I’ll send a pic when it’s sanded and painted

Cheers,

[BIBO3Dtech]

Thanks so much for your sharing always:) Your works are very awesome. Waiting for your T-Rex work!

[UVic_3D]

Hey Bud,

I’m not going to be able to finish this for a few weeks, but here’s a sneak peak of what it looks like after the first coats. Once these bloody exams are out of the way I’m hoping to wrap it up in a couple days.

Cheers,

[BIBO3Dtech]

Your work really looks cool, and good luck to your exams! Thanks again for our sharing.
