Why 3d printing IS a good tool when making props… if done correctly.

I must say that after a long hiatus, it feels good to be back to doing some actual building again.

The break was, of course, due to my daughters health, and even though the path to get her well again is long and uncertain, We still need to find these things in our lives that gives us strength, that gives us peace of mind and the energy to move on through these dark times.

For me, that meant taking on another project. I’m going to be a Ghostbuster!

(Costume still in progress)

Ever since I was 11 years old and went with my father to see this movie back in 1984, there’s been something about it that I’ve always cherished and held dear to me. A few years back I was happy to borrow a uniform and proton pack for the annual Sci-Fi convention in Stockholm and it was nothing short of awesome. Time to make my own!

The picture above is a work in progress of the costume. I am still awaiting arrival of my belt, but the rest of the gadgets that go on the suit have arrived… I just haven’t pictured them yet!

But, I digress. Apart from drawing and printing the hose connector (grey thing that holds the yellow hose) on the uniform, I’ve started to draw and print some of the things that go on the proton pack and gun… not to mention the fully 3d printed trap …

On the proton pack, I need to have what’s known as a Clippard Valve. I decided to make one on my printer. First off: time for some cad:

First print off the bed was not as smooth as I wanted, due to some of my export settings not being fine tuned enough for the circular top. I exported and printed a second one that was slightly smoother, but kept this for reference. It is a good reference of what a raw 3d print looks like, even when printed in good quality.

What I don’t get is this: Many people that 3d print parts for costumes or gadgets never put in enough work with sanding and polishing the 3d prints, making them looking not good enough!

This is not going to happen with my Clippard!

I started off by sanding off the biggest irregularities, getting it fairly smooth, then a coating of spray filler … then sanding again to get it smooth.

A few places (most notably the top of the thumbscrew on the valve) was also hit with a few coats of Tamaiya Putty, to remove the print lines. Again, sanded away most of it, to get a smooth finish.

Once sanding was done, I painted everything black. Two quick coats did the trick.

Although it is cold and freezing outside, I still painted them quickly and then used my fiancées hair drier to harden the paint just enough so I could bring them inside without smelling the place up.

I then masked the top portion away and clear coated the majority of the body of the valve.

My plan was to use Silver Leaf Rub and Buff for the metal part of the top of the valve, and as experience have shown me, this does not stick well on clear coated surfaces, but on raw painted surfaces, it fit just great! I also treated the top screw with Rub and Buff.

Once that was finished, all that was left was to add a metal sticker on top of it, to create my finished valve. Please note that in the pic below are two different types of valves, so they should look slightly different. The one on the left was my 3d printed version.

And … as a final comparison, here are the final result compared to the 3d printed raw print. The knurling on the screw could be slightly better, but it is only really visible when being very close to the valve, and I am giving you the full horror here…

All in all, I am happy with the results, and this baby weighs just a few grams as opposed to the original, which ways about 100 times more. Every gram counts when you wear it on your back!

I will be back shortly with more about this new exciting project!

cheers,

Micke

BB-8 progress

Time for another update on my BB-8!

Things have been going well, and this week I printed the last pieces for the body:

In all, that makes quite a large stack of pieces that I need to go through and sand and treat and all that..

More importantly, I started experimenting with the weathering. First take a look at my kickass weathering mount setup!

IMG_9476 IMG_9475 IMG_9477

Once I had this on the inflatable ball, weathering was fun and easy. I must say this is a process I really do enjoy.

IMG_9478

This was only a test with water colours, soon the real weathering will follow, this time with acrylics!

In addition to this milestone, I also got around to making a new PSI, since I lost my old one. Putting it all together looks really nice too!

Stay tuned… =)

BB8 Dome nearing completion

I hurried putting my dome for BB-8 together for the Sci Fi convention in mid September. This included doing a quick (and not nearly good enough) paint job to just get the dome to some sort of colour.

IMG_8519 IMG_8528

The paint was too thick in places, and I had not had enough time to do a proper job concealing the joints. You can really see the joint on the left hand side of the picture quite clearly.

I also had no time to really let the paint dry before I hit it with the clear coat, so it all sort of blended together. Not to mention the ugly skirt..

To fix the skirt and the dome ring, I needed to print new parts, something I have done and are still in the process of assembling.

Paint job being botched (and no orange) aside, it still looked pretty cool!

IMG_8538

Not to mention the extreme close-up .. 2001 warning ahead:

IMG_8540

This got me through the Sci Fi convention, even though it was just a base.

Being back home, I sanded the clear coat and most of the paint off, worked over some of the problem areas with some putty filler, sanded again, and then applied 3 coats of spray filler, before sanding it down AGAIN with 400 grit sand paper to a very smooth finish, before I applied the white paint again. No more problem areas, and no more visible joints!

Once the dome was white (again) and the paint had cured, I taped over the entire dome, and cut out the portions that was going to be orange, and then hit the dome with the brand new orange paint I had custom ordered.

Once cured, the dome looks GREAT!

IMG_9113

After the paint had cured properly, it was time to hit it with the clear coat.

IMG_9115 IMG_9116 IMG_9118

The dome feels incredibly smooth.

Time to buy a can of dark grey and tint the Radar Surrounds and the Holo Projector (and the Holo Projector ring) in the proper colour and mount them.

The only annoying thing is that I had made a really good PSI that should sit in the smaller hole on this picture, however, when cleaning out my workshop the other day, I suspect that small PSI that I wrote a nice blog post about, accidentally found its way out in the trash…

IMG_9081

Ah well, you gain some, you lose some. I have updated the 3D model for this, so next time it should be a lot easier for me to get what I need to get done!

Next up is putting some more focus on the dome ring and dome skirt so I can paint and mount them for a finalized dome structure. Can’t wait to get this part of the build done so I can start weathering the dome, I’m really looking forward to that!
