Sliced Armor™ technology.

[bevbor]

Hi all!
Here I think about to divide armor models to slices.
Why?
Because we can print out each sliced part section view and stick it to whatever we want - matboard, wood, etc.
Then - cut each thing out.
Then - glue them together on original order.
As I see there will be no more than 30 prints in model of helmet.
So, what do you think, dear comrades, can it be useful for people
that are'nt so accurate or just lazy for doing pepakura?

Best regards.

Here is the picture illustrating my thoughts

Result may be less detailed than last pepakura models, but still it is good base for glassing, bondoing and detailing, or isn't?
What do you think, what slices can be more useful - frontal, side (as on the picture), or horizontal?
Best regards.

i really don understand it, but im just commenting to be nice

Hmmm, I like the idea.
It would be much faster than pep, but less accurate. But like you said, it would be a good base.

Interesting idea. Maybe you could divide it into more slices, to retain more detail. If it were 50 or 60 slices, you would only have to cut out 50 or 60 parts,(still way faster than pep). Of course that would depend on the thickness of the material you cut it from. For a helmet, you could make a solid model, resin the outside, then carve away the inside.

I like it ^^

 

[chiefer]

Should their be a stated thickness of the material you need?

 

[JoeyCoz]

This could be useful un making molded armor as well. If you scaled your model a little smaller than your finished piece, then divided it into 1/4" slices, you could cut it out of 1/4" foam and use it as a base to apply clay to. this would give you a somewhat accurate base to begin with as well as reducing the amount of clay needed.

 

[bevbor]

Should their be a stated thickness of the material you need?

Yes, sure, it must be stated.
For example, if you using 2mm thickness material with general scaled helmet (26.5 cm height, 23.2 cm width)
you'll get 116 slices or 58 pairs of same left/right details.
If you use material of 5 mm thickness you'll get 46 slices or 23 pairs of left/right details.
Etc., etc.
But since sectioning is fully automated in CAD programs, it isn't problem or lot of work.
Finally we'll get library of sliced models with any possible thicknesses of materials.

Could be great for vaccumforming.

That's exactly what I was thinking. It's alot easier to build up half a model than to cut a full one in half.

 

[bevbor]

Started to play with helmet 3d model to get slices.
I found it pretty easy.
Currently I have to get more detailed model to do something serious.
My current model isn't ideal I think.
Here you can see slices of 5 mm thickness.

UPD: More slices. Isn't perfect on this model.

UPD:
After a little game with low poly model I've got 23 slices (with 5mm distance) of one side.

Now all I need - more detailed model.

Nice idea... much the same way some rapid prototyping works... just hand assembled... could be very useful for a quick base to be smoothed and detailed later...

 

[Loess]

This looks like it would be a great base for a clay sculpt. Even with a low detail model, the symmetry and general shape from the built-up sections would be nice to start from.

Great Idea!

And I even have a nice new scrollsaw that'd be perfect for this.

i like the idea, i seems to have inspired a few alternate ways of going about several methods of armor building, ie molding, base for detail etc good idea

 

[bevbor]

Now I think to add two horizontal holes through all slices.
For easy assembly.

Thanks!
Can dear Mods move this topic to "Molded armor discussion", please?

Congratulations with your new saw!

I planning to make some molds with this method.

Eh, I kind of think you're going to have a LOT of work to cut out each of those 20-or-so profiles, glue them all together (without adding thickness), then sand off all the extra, and smooth on top of that.. might be easier just to heavily reinforce a pep helm. You should probably post an assembly of each profile extruded to the spacing size, to further illustrate the idea for people.

Another concern is that this might not be the best way to split up the helm for vacuforming.. or assembly.. wouldn't slices that stack vertically be best? Also, I know the helm would have to be vacuformed in at least three pieces... probably more like 5- helm top, under brim, front muzzle, and each side on the back..

If you're trying to help vacuformers out, maybe you should split up your model into each vacuformed piece, then slice it so the pieces will stack vertically for easy assembly.

One of the pitfalls of CAD is that you can get wrapped up in the theoretical, and lose touch with the practical.. CAD is nothing if it's not useful, and I don't think this is, sorry.

I don't know...this seems like more work and a lot more use of paper. Spase was correct though in saying this is close to Rapid Prototyping Methods, and I'm sure he even knows what I'm about to point out.

Besides not having a maching to cut out all the layers for you and glue them together, this is actually a certain type of Rapid Prototyping. It's called LOM for short. It stands for Laminated Object Manufacturing. For more details on this process, check this link out.

Here are a couple pictures to help as well.

Basically, it's exactly what you described here. Slices of paper, layered on top of each other, and glued together. Only thing is this is usually done by a machine.

I think this might be creating more work than is necessary. A lot more paper waste as well. It would be an excellent way to get a sturdy base model to work with, but it will just take so much longer than doing all the work with pep to begin with.

Sorry dude.

 

[Loess]

Paper would take forever, but thicker layers of something like foamcore or MDF (5mm, 1/4", etc.) would work perfectly well for getting a general shape to sculpt on, and would add up fairly quickly. If you have the right tools, this should work well.

sorry.

I'll consider your remarks, thanks a lot.
Idea about divide model for 5 parts - I like it.
And I definitely want to show extruded layers too, unfortunately it's possible only tomorrow.

I didn't say about layering PAPER on PAPER, I mean layer print (on regular paper) of slice, stikied to some material like for example 5 mm thick cardboard, cut out, and then layered on top of other such 5 mm thick cut piece. Where are you see more paper waste?
Here on my model I got 23*2=46 slices, are you sorrow about 46 A3 sheets? I'm not.
