From theory to practice — 3D model-making, modifying, rebuilding, printing and reflection

After I decided to make some communication objects as my final outcome of my project, I was thinking about 3d printed objects. That is a good website— Thingiverse, which has lots of free 3d models on it. What I need to do is pick models, download them and put them together in order to make new and wired things. My first experience of 3d-model-modifying was about a burger and a mask. I needed to match them together, but I never use 3d programmes before. So after I ask lots of tutors like IDA and IDC technicians, animation tutor,…, I downloaded Maya, Meshmixer, Sketchup, but I still could not do it. I thought that’s really easy and I can finish all of the objects within two minutes, but…3d’s not actually easy. TRUST ME! DO NOT DO IT JUST ONE DAY BEFORE THE DEADLINE! I started to find other helpers. Luckily, I found a friend which just graduated from BA Moving image at Central St.Martin this June. He helped me making 2 models which are burger mask and horn Toyota.

Pile again….

I thought everything was done until I printed them. Because the original files were downloaded, some of them were rendered and used in animation, so there are lots of issues in these files so that I need to repair them before printing like lettuces are too thin, wheels are too detailed, etc. I found the size of Toyota is too big(170MB) because three same cars overlap with each other(in C4d, if meshing two components to one object, the programme will generate a new object which includes two components covering the old things rather than directly combine two parts, that’s why… ). The moving image guy’s really busy on daily life, therefore I must learn how to edit them in Cinema 4D. It’s not easy for me. Luckily, a C4d expert at digital space of my uni—Macco, taught me how to edit models in C4D, like rotate, zoom in/out, move, combines parts to one object, and separates one to several parts, build models, add effects, etc. Finally, I finished the models of burger mask and horn Toyota and printed Burger and Toyota as experimental.

Rough Rough Rough Toyota… just after a typhoon…

What a really really rough Toyota it is!

The burger looks like a macaron rather than a burger, so I added more layers in the burger in order to make it thicker and looked like a big MAC much more rather than a Macaron.

For the car, I figured out the reason why it was really rough because of too many details inside of the car. If I want to make the surface of the car rather than the structure, I need to delete all of the details inside. I also need to change the position and shape of the horn because it looks too normal now. So I put the horn at the front of the car and curved it for making the car looks more like a Rhinoceros. That’s going to be really wired. For the ‘burger mask’, I need to make the burger bigger so that making it more strange and likes a gas mask much more.

After that, I started to edit other two models, Bats drone and Doorbell camera. I’ve to say the best way for model users, is building them rather than downloading. The models of downloading always faulty. Looking at the camera, I cannot move the anchor point close to the camera, or the camera passed over the Axis point, but it should be keeping relatively static with the point. It must have some hidden things, thus I need to rebuild a new camera. Firstly, I need a cube and a cylinder; then add effect of boole on the cylinder, and how many cylinders you have that how many booble effect you need to match with. Finally, with Macoo’s help (sorry I was sleeping for a little while when he was helping me, I was really sleepy), the cube looked like a CCTV camera. That’s really funny and I loves 3d models now. To be honest, these models still have some issues but I have passion this time, so everything is enjoyable.

However, because of moving these cylinders, after I exported the file, there’s a big hole on the camera that not printable and I must fix it. I spent two hours but could not done. So Macco helped me making a new one and recording the process with quiet time. Here are two links below about how to building models. Hope them help.(Special thanks: Macco) For the model of bats drone, it’s much more easier to match them together. Then I printed them. Anyway, I love C4d!!!!!!

For the Bats drone, the bats are too thin to break, so I need to modify the model or change another 3d printer. Doorbell’s really nice,without a camera inside.(Thanks Tom!)

So I went back edited models again. I downloaded a new model of drone and deleted something not necessarily, repaired some holes on these bats and put 4 bats on the drone finally.

Then I printed them again. I tried to print them as big as possible, like the mask, I tried to print a full size of real mask, but for the limitation of the 3D printer, the maximum is going to be 26cm*26cm*26cm, and for lucky charms, they could be really really huge like a statue or really really small like a mirror hanging or necklaces. That’s why I printed a small version of the mask with PLA.

For the materials, I was considering about resin because of more delicate but the price of it is really high(£125/L) and much more complicated than PLA printing. What’s more, if I print the car with 5cm*8cm*6cm, it will spend 23hrs, but the orange machine maximum can be launched last for 7 hrs or must be released. Here’s the link of Resin printing through Formlabs and one more video link:

Printed it well, removing the support, well done!!!

For the reflection so far is : 3d’s not easy but funny, if I have enough time, that is will be better! After printing them, I still need to remove all of supports and sand objects. That may hurt me.

I started my models from the 4th of Nov, I’ve not printed all of them welllllllll until now!!!! Come on!!!!!!! T^T…..
