Mechdonalds Printed by Grafit February 27 2019
He is from Hungary and we met on Twitter while he was using our materials for really nice and clean printing. “I am already helping Fernando with his top secret project, beta testing at 40% size”. We knew we are on the same page to make some good collaboration!
*Fernando Jerez is our long-time friend, he’s talented designer who started the wavey madness with his generative design.
When I was asking you about some ideas for a new bigger project, you wanted to print exactly this amazing design by Juri Pranjic. How did you find the model?
I have seen this earlier on Twitter when Juri designed it and started printing his own. I became a follower of @3dworkbench instantly.
Two materials in seven different colours, tell us more about the printing process ... Which printer you used, how long did it take to print? Did you use any tricks or special set up for printing?
Well, the CPE Red Hood filament was a completely new material for me. And because it needed high temperature, I used my Prusa i3 MK3 for that job. No failures there. It came out nicely in the first round. On the pictures you can see, it is the tomato slice.
Since I scaled up this awesome model to 140% I had to use some tricks. For example, on the original model, every part of the burger is solid. However in a perfect world, you will never see the inside of the tomato slice, and the meat etc. so I decided to cut out most parts. The tomato slice is a ring eventually. I will post some making-of photos on my twitter later.
Ender 3 printed the burger buns (Light Ivory PLA), and the limbs (Vertigo Grey PLA). Everything else was printed on the Prusa i3 MK3.
Fries & Cheese (Melon Yellow PLA), Lettuce (Grass Green PLA), Meat (Purple Red PLA), Shields (Traffic White PLA)
Did you have any issues with stringing on CPE? Because when it’s moist, it can be hairy printing.
Moisture did not get any chance since that was a perfectly packaged brand new spool; and after printing, I put it right back to the reusable ziplock bag. :)
It’s not an easy design but definitely worth it. What did you need for assembling it?
For the burger, I have used hot glue gun. And I designed and printed a custom fitting ring for some of the parts. The legs and arms are just slide in. For the thrusters, I used a small strip of kapton tape to make some friction so they would not fall out.
With upscaling to this giant size there can be an issue with stability which isn’t there in the original size. We almost didn’t manage to make it stand. Do you think it’s something what can decrease the head part weight to reduce the pressure on the legs? Of course he is super-awesome while sitting too, but.. : )
Yeah, the upscaling generated some issues with the tolerances. His joints became a lil’ loose. I think the main issue are the knees. I would glue them to a fix position, or drill and use a screw and a nut through the knee joint. I was able to get him standing with fries box on his back. :) I have a proof.
What are your feelings from Fillamentum materials?
I really love just everything about Fillamentum. The box, reusable ziplock packaging for moisture defense, beautiful glass clear spool, and of course, filament itself. It comes in beautiful vivid colours and quality material. I’ve never had any problems related to the material. Oh, and the surprise stickers! :)
Thank you 💛
The world is divided into two parts…. Ketchup or mayo to your french fries?: )
Any ambitions for next projects?
I really like multipart models where you can combine a lot of filaments together.
That is where nice colours and glittery materials can show their beauty and form awesome combinations together. So definitely I would print something big, multipart thing with perfect material combinations.
I recently started to paint some models but then you can just use any filament. :)
Laila for scale : )
