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!
Tim
Hi Tim,
What machine was that printed on, it looks great!

Hi Dave,
Thanks!
It was printed on an Ultimaker 2+ Extended.
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!
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,
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,
Thanks so much for your sharing always:) Your works are very awesome. Waiting for your T-Rex work!
Your work really looks cool, and good luck to your exams! Thanks again for our sharing.
