I LOVE this technology. Just think of the possibilities..
Great job on the designing phase too.

Re: 3D printing KH Body Attempt
 

Oz,
Yes there is. That is the next technology that needs to be made more for the consumer base. Just as the 3d printers have become. The real good scanners which use lasers to define 3 dimensional objects are really pricey now, but ive seen people hack The Xbox Kinect to be used as a 3d scanner. Microsoft has caught wind of it and has realized the market for poeple wanting to scan for 3d prining and has said they will release a version of the Kinect for scanning sometime this year. You can also so search youtube for 123d catch which is a program which utilizes multiple photographs taken with a camera to produce 3d imaging. I have the app on my Iphone and its pretty neat when you get all the lighting right..Youll need to clean up the model in a program like Autodesk Meshmixer which fills in holes and fixes details..then you are able to export your model into am STL. file which is what 3d printers recognize and can pprint.

Re: 3D printing KH Body Attempt
 

You can modify a xbox kinect for a poor resolution scanner. IMO it's only good for rough body scans.

Personally I am waiting to see what the Leapmotion can do. https://www.leapmotion.com/ They claim resolution down to .01mm. for about 80 bucks. Assuming they can hack it for 3d scanning of course.

Then there's also projecting laser line using a web cam. That does pretty good results.

Lots of info on youtube.

Re: 3D printing KH Body Attempt
 

Thanks Al!

Yes, im familiar with that too.

Re: 3D printing KH Body Attempt
 

Oh, thats low guys...

Then again, I'm glad I'm single, with only a feline to get in my way. I can blame her for anything and everything, and not have to worry about my stuff ending up on the lawn (which is bad, as I'm on the 4th floor!)

Only thing is that I ~may~ have to watch where I step if I ignore her too often...

Now I wonder if I can talk JDH into making the slabby body of an Oshkosh HEMTT, or one of the M35-series beasties... (the 'Nam successor to the venerable CCKW-353 'Deuce') The M35 cab alone would be great, as its still in use in many areas... and with more body's than one can imagine!

Re: 3D printing KH Body Attempt
 

Ahh, that hood combined with the fenders and grille....beautiful! This is going to be one of the nicest cabs ever. I can already see it. Beats scratchbuilding with styrene, that's for sure! It's going to be a one of a kind truck, when done, and I can't wait to see it.

Re: 3D printing KH Body Attempt
 

So if something was to go awry, what is she to do? Pull the plug? Hit a button?

What's the worst that has happened in your absence?

How many hrs of trial/error do you have logged (approx) to get to the level you're at now?

Re: 3D printing KH Body Attempt
 

Wow....this is definitely one part of new technology i can say is well worth it

Re: 3D printing KH Body Attempt
 

Sp, Thanks man, Im trying..I wish i had a fraction of the skills to scratch build like some of the guys on here do and did like FGD. What a legend.....

Maybe by the weekend i should have more parts ready to assemble.

Joe, theres a killswitch for just such an emergency. The sucess rate for a print is around 95%. the occasional mishap us usually software related but once i figured out what causes some of the probs ive had iv been able to prevent them. Im pretty confident to leave it run unattended now.
Hours to get to where i am now as far as smoothness of the whole process...lol lots of late nights for the past few months...maybe 100 hrs of experience roughly.

I set up a wheel to print last night to play with this morning at work. Wanted to try some smoothing and painting to see what i could get.

with a primer and rustoleum metalic..not a fan i prefer Krylon alum better but this was all i had.

A Clearcoat removes the super metallicy look.

https://lh4.googleusercontent.com/-n...2+11.41.25.jpg

The picture doesnt do it any justice...it looks much better than it does in picture. Id prefer a flat clear finish..think it would look much better and closer to oxidized alum and hide the uneven surface which is cool with me because this truck is going to be a working class truck and a dump truck doesnt always look like a show truck.

And for those of you into the Garth Knight look.. again, a flat primer black would look better.

Re: 3D printing KH Body Attempt
 

Id like to print another set of these and use hardware to simulate the lugs. Anybody know if you can buy just the screws and nuts that RC4WD uses on their semi wheels? Im actually missing 4 from my set of white front steel beadlocks. Id like to get more. thanks

Re: 3D printing KH Body Attempt
 

The rim looks great, Jason. Honestly though, I don't know that I like the way it looks, coming out of an acetone dip. The clean edges it had before hand are melted and somewhat obscured. Perhaps it would be better to lightly sand the surfaces by hand? Can't complain to much! It still is very cool to see something like this made.

RC4WD does have 2, 2.5, and 3mm hex head scale bolts. Not sure what size you need. If those aren't small enough, Scale Hardware has American sizes even smaller!

Re: 3D printing KH Body Attempt
 

Oh wow, great. thanks for that info. I think like you said sanding the face would be the way to go, good call. On such a small part the acetone really removes the hard lines but i wanted to show an example of what dipping can do for anyone interested anyway.
Sanding will be alot easier too without the printed lugs.. :)

Re: 3D printing KH Body Attempt
 

No problem, JD. Here are some links, if you are interested.

Re: 3D printing KH Body Attempt
 

I wonder if the acetone vapor process would smooth out the build lines and still leave some detail. Being that it takes longer I would think it would be a bit more controllable, but I haven't tried it myself at all.

Re: 3D printing KH Body Attempt
 

Awesome work there JDH..
Nice to see such a success with the 3d printer. I have toyed around myself with the 3d printers.
I have a Makerbot Think-O-Matic worked great for a couple of years but having trouble now... What is your 3d Printer make and model?


Regards,
Jeff

Re: 3D printing KH Body Attempt
 

Sp, your the man! thanks for the link. Never knew about Scale Hardware..looks like a great place.

Pugs, i dipped this wheels a few times to see if it would smooth out all the ridges so im sure one dunk for just a second or two would have been less aggressive. Let me know how the vap goes if you try.

Just a few pics after moving axle forward and printing a prototype cross member.

https://lh5.googleusercontent.com/-d...2+15.40.25.jpg

Crossmember with hood hinge,and servo mount. Also using it as a front spring hanger to figure out positioning. Designed it with multiple mounting holes for adjustments.
Will reprint and add the bumper mount after i figure out what looks the best.

Re: 3D printing KH Body Attempt
 

Thanks Jeff, I have an Afinia. I like it so much i bought another one to have at work. I use them often. Its a great printer for many reasons. Search Afinia/UP printers on youtube. Lots of good info there. Thanks for lookin.

Re: 3D printing KH Body Attempt
 

so what is your total print time so far?

Re: 3D printing KH Body Attempt
 

Wow that is incredible! I could see that becoming a full time job producing cabs, and such. The possibilities are endless.

Re: 3D printing KH Body Attempt
 

Dirt, ya its time consuming for one cab.

Izzy, fenders- 4hrs each, hood top-2.5 hrs, hood main -5 hrs, cab roof-4 hrs, cab rear wall 4 hrs. 23 hrs roughly so far, and prob got another 10-12 hrs for the rest of the cab im guessing...but thats what i said initially for the whole job...:o Still have the body mounts, and cross member to work out. If i changed the quality settings on the printer I could cut the time in half probably...But they always say you cant rush a good job so what an extra 12 hours or so.;) Im not in a huge rush. I hope it ends up looking as good as i planned...what a disappointing build up if it ended up looking like garbage.

Re: 3D printing KH Body Attempt
 

Re: 3D printing KH Body Attempt
 

The height seems a tad high. Thinking of moving the hood hinge down .150" - .200" to bring the fender closer to the tire.

Re: 3D printing KH Body Attempt
 

TamiyaCowboy, Thanks! Ive got a few hours logged with the printer, but this is my first time trying to replicate a 1:1 object or printing something this size.

Re: 3D printing KH Body Attempt
 

Hey! Looks like a stock Wedico! :p:D. Isn't that right Craig, Nathan? ...:D lol

A machine is only as good as its user ;)..... Great work so far and thanks again for taking the time to share the progress. You are a pioneer of the next level in this hobby. :cool:

Re: 3D printing KH Body Attempt
 

Are you using a single nozzle printer and building the supports with the same material that the part is printed in.

I have access to a small makerbot but I haven't really used it yet. The plastic rolls for the machine are very costly in my opinion. They do have a water soluable plastic that you can build the gussets out of if you have a dual nozzle machine. But that stuff is very pricey too.

It is great seeing someone use some of the great Technology available to us for this hobby.

I'm currently learning to use autodesk inventor. I'm trying to make a few molds to do some vacuum forming with.

Keep up the good work anxious to see the rest of the build.:D

Re: 3D printing KH Body Attempt
 

Mario, Thanks

Lost, Thank you

Top, My machine is a single nozzle. The Printers software builds the support material automatically based on the design. The vacuum forming molds is a great idea. Post up some pics when you get some, Thanks

A few pics of my progress, I need to cut about 1/2" off the bottom of the cab and im shortening the frame 1 1/8". I decided to use a different brand of ABS for the doors as its easier to remove the support material from such fragile areas.
Cab consists of 10 separately printed parts and feels very sturdy now thats its assembled. But, something doesnt seem right. I cant tell what it is about the way it looks. the hood is too long,or the side windows are too big. Maybe the angled roof is making look weird. looks more like a Duece and half to me than a 900B. Maybe after i get further it will look better to me.

thanks for looking

Re: 3D printing KH Body Attempt
 

Simply amazing......There is another firend of mine on the board that works with 3d printing (medical) and i am always intrigued by the stuff he makes......

Re: 3D printing KH Body Attempt
 

that is looking outstanding very nice work

Re: 3D printing KH Body Attempt
 

This is coming together great!
I agree something looks a little off though.... I don't think it's the windows. It's the top rear edge of cab seems to slope a little different than the autocad drawing you posted a few days ago? Maybe that is causing the deuce look?

Mario

Re: 3D printing KH Body Attempt
 

Thanks guys, Mario, i think your right. I did modify the cab a little since my original drawing. I was leaning in this direction...
http://www.truckntrailer.com/clients...s/133201/2.jpg

Ok looking for some feedback on this. I changed the roof line. Top is what i printed, bottom is redesigned and more like the original drawing i posted on page 1.

https://lh3.googleusercontent.com/-D...5+19.50.23.jpg

Re: 3D printing KH Body Attempt
 

It could just be an optical delusion from the 2 different colors. Either way its coming together nicely

Re: 3D printing KH Body Attempt
 

Your hood is too short heightwise and has no slope to it. Grille is too low & too much fender at the front.

Looking at the 1:1 you posted, the bottom of the cab is almost even with the top of the fenders... that's always been one prominent feature of the KW is what a tall hood they have.

Re: 3D printing KH Body Attempt
 

After seeing the 1:1 pic you got the roof line perfect:confused:

I think Joe is right about the KW look and the big hood with the cab sitting along the top of the fender. That alone would change the look a lot.

Im not being a critic. I know absolutely nothing about 3D printers, saw auto cad at a university back in the mid 90's once but when someone is doing something as epic as this build, I feel it's only proper to share honest opinions and try to help out :);)

Mario

Re: 3D printing KH Body Attempt
 

Joe, your absolutely right. Forget the roof line...The fender height to the bottom of the door is way off. I never saw that before. Along with a few other things. Back to the drawing board. Thanks for the observations.

Re: 3D printing KH Body Attempt
 

Mario, thats exactly what i was looking for...Ive been looking at it and it just wasnt working out somehow. The pic i posted was just for the roof design, but the fender to door height is the same from 900L to 900B either way so...Ive got alot to learn when it comes to modeling. But whats great about this process is i can go back and make some changes and reprint. Its prototyping. Thanks for the help guys!

Re: 3D printing KH Body Attempt
 

Could you section the hood with a saw, then reprint what's needed where ever?

I suppose proper centering/starting point might be a problem?

Looking forward to the updates. :)

Re: 3D printing KH Body Attempt
 

Thanks Joe, ill see what i can come up with but most likely going to reprint the whole thing. Ill let the machine do the work.

Re: 3D printing KH Body Attempt
 

Interesting project. You´re doing a great job.

Re: 3D printing KH Body Attempt
 

Egronvold, thank you

Here is my revision that i think looks much better. I should have named this thread "attempting to model 1:1 truck" cause i think ive got the printing part down.

Re: 3D printing KH Body Attempt
 

I think your on the right track..I did find this vector drawing that may help as well to compare ...just google kenworth w900 vector drawings and see what you come up with in images as well..You did a very nice job removing the extra support material..how do you go about doing that ?..Great thread ..
