Props 3D printed Halo 5 Cortana Chip

FlyinPhil · Oct 7, 2014

I recently found out that the public library here in Edmonton now has a couple 3D printers available for public use. The only cost is 10 cents per gram of PLA plastic. Now I've played a bit with google sketchup and similar programs before, so I'm not completely new to 3d modelling, but I had never created a working model, or something that can be exported properly in an .stl file type. The library suggested using a program called "tinkercad". So, I popped onto it, played through some of the tutorials, and was able to model myself an AI chip. Note to other 3d modelers: this program is quite rudimentary (as far as i could tell anyway), and you create all of your shapes using their basic shapes provided. That being said, i was able to create a few shapes and contours that I am unable to do on sketchup. With some creative thinking, this is a fun little program to learn to 3d model on.

Here are a couple progress shots on the modelling, i'll be heading to the library to get it printed on thursday.

Only one side is detailed, I intend to print off two copies, and then bond them together. Thanks for looking!

Looks good, Phil. Nice job

What are the dimensions of yours going to be when printed?

Thanks!

The finished dimensions will be about 8cm long, and about 4.5cm wide. I'm not sure if it will be a tad large or not, but i can always scale it down on the computer if needed.

Ah, okay. Looking at those dimensions on a ruler, it looks like it may be a little on the large side, imho.

I think 7cm by 3.5cm (or whatever's proportionate to a length of 7cm) would be good. Just a friendly suggestion

Was just playing with my paper prototype and a ruler, and I would have to agree. I scaled it down to about 7 cm in length, as per your suggestion, and i think that will be perfect for sizing. I'm excited to play with this printer tomorrow, and I'll upload my results!

hej man are you going to share the model?

what kind of printer they have? it has a lot of tiny details.

As of right now, I think I'll keep the model private. I'm not 100% sure what models their printers are, but i do know that they have up to .4mm variation, so I might have a bit of tidying up to do on the prints.

So i found out that there is unfortunately a 5-6 week waiting period on the printers, but they have my model in their system and will be giving me a call as soon as they begin the print. I'll update again once i have the printed model in my hands!

ugh. thats a pretty medium quility for such a detailed print.
I think they are using a fdm printer with filament ( the normal type these days)
you might want to consider printing it whole and standing up in stead of split up laying down.
fdm printers can have super smooth side surfaces but top surfaces is not something they excel at. you will almost never get it smooth and will see the printing lines really well. if the infill is

I would also recommend since its such a small object to fill it in 100% instead of the normal 20/30% so you wont have holes in it. if you decide to print it laying flat

for example the part on the left was printed standing up the part on the left was printed laying down.

Thanks for the pointers. This will be my first piece printed, and I don't really have any say in the printer settings, aside from the color of the filament...lol. The staff at the library didn't seem to know a ton about the printers/process , so i'm just going to go with it for now, and see how things turn out.

Another option, Phil, is a printing service like Shapeways, they use printers that far outmatch anything FDM machines can achieve.
Though there is certainly something to be said for learning the printing ropes first hand instead of letting a company do it for you.

My suggestions for the settings would be as low as something like .1mm for the most accuracy and indeed a fairly high 'infill' setting. If it's printing in PLA you'll want to print it quick so it doesn't ooze around too much.

Thanks for the info, Serin! I'm learning a ton from the info you guys are posting, and I really appreciate it! Looking forward to posting my results on my first print when the library gets around to my model.

Finally got to pick up my print! it's definitely going to be a lot of clean up work, but it gives me a really good base for finalizing the master.

Looks awesome!

nintendstroid · Nov 11, 2014

It's not bad like i said if you printed it standing up it might have come out better and you could have printed it in one go

still looks good dude!
