In Topic: 3d printed LS engine block

Chris, I built the printer. I have less than 1k in it. The most expensive purchase was the Acer 6510db dlp projector. It ran $607, but is considered one of,if not, the best. Makerbots are filament layering printers like my diy Prussa I3 in my avatar. Not really something you would not want to consider. Formlabs1 is an sla printer. That is, it uses a laser to cure the same uv resins that the dlp beam does. The B9 creator will go to 25-30 microns. Where it can get confusing is understanding 3d printing and these numbers. I may very well get to a 10 micron layer height, but that isn't really needed unless you like to wait a long time to print something. My engine block was printed at 100 microns layer height. The height is the z axis. x & y are the side to side and front to back axis. A filament printer uses all three. The laser printer uses all three. that is what creates a non smooth surface. It is also very time consuming. A dlp printer projects a beam of uv light that cures an entire layer in 3 to 6 seconds. There is only an x axis that moves. It took 39 minutes to print this engine block. I could easily add 3 to 5 more on the build platform and print 4 to 6 engine blocks in the same 39 minutes.     


 Doug.... Thank you so much for taking the time to explain it. That is awesome you built this printer for 1/3 the cost of these others out in the market. I have been eyeing a 3D printer because I think it would be awesome to have and print my own parts. But I have been sending my 3D models to Shapeways and having them print them in the Frosted Ultra detail for my 1/16th scale builds. That is so cool you can get down to a 10 micron layers. I might have to consider building my own printer one day but at the moment I really would love to get a mini mill and lathe so I can machine some parts. Do you have a pic of your printer you could share with us by chance? and from what I am gathering here is that the DLP printer is beter than the SLA printers. Looking forward to seeing more parts that you print up.

Very nice. What was the brand and model number of this printer? I would be interested in looking at the resolution. I know makerbots are 100 microns... formlabs printers are 25 microns. And this part looks way better than a makerbot printed part.

Chris, I'd like to see what you have in store for everyone on your LSR car.  Mine took many variations to get to the point you see it now.  You can really let your imagination run wild which is one reason I like the whole idea of Bonneville and the cars that run there.  The Speed Demon car set records with everything from V8's to 4 cylinder engines stuffed in it.  A testament to their overall design and engineering of the overall car.  It will be interesting to see what they do with the next one.

Tim... a while back I picked up a 1/43rd scale North American Eagle LSR resin kit. Its a F104 jet that was converted to a LSR car. It looks sweet but at one of oir local swapmeets. I picked up a 1/32 scale F104 that I am gonna convert to a LSR of this North American Eagle. Thought it would be cool.

Tim.. This is outstanding my friend... I am totally digging it and can't wait for more. You are a pure craftsman. I am blown away at what you have done with this. Its gonna be another masterpiece just like your Henry J. I am already itching for an update on this bad boy. Seeing this makes me want to build the LSR car that I want to do.

Danno... and you are just telling me that now buddy??  :P  I guess I never got the memo before LMAO  :lol:


Scott.... Thanks brother....  OH  man that is some great news about cleaning the was off the FUD material on the 3D printed parts. I am going to try that one some of the others I have to see how it does. I think I have some in my garage. If not I will pick some up at Lowes. This little speed bump won't stop me, I will just have to spend a short amount of time remaking the new tin. just glad I still have my template and all I will really need to do is cut the material out bend it. The hardest part is going to be getting the mounting holes drilled in the correct location....lol


Hakan... I sure learned my lesson on using the purple pond with metal. Althought I am going to a sample test by putting a pieces of aluminum and brass tube in the pond to see what it does. I think it may be cool to be able to use that technique to use for a diorama or some sort of weathering. I learned from a dear friend years ago to use Ammonia to remove chrome off chrome plated parts. it seems to work pretty good and doesn't take too long. but I will try the pond as well.


Randy.... Thank you for the kind words about this build. I really have been enjoying sharing this build pretty much step by step so everyone can see how I am doing things. I have to say I am pretty fascinated with the 3D printed parts and being able to create parts that aren't available so eventually I will make them available on Shapeways but before I do I want to get them proved out first since I have had a few features not print correctly  or should I say left off... lol for example on my injector hat for the blower it left off some of the holes for the injector lines and the butterfly shaft. and I believe the reason is because I made the hole to be .016" and I think its a limitation of the printing machine. so I will have to open some of them up to .020" to see what happens the next time its printed.  I don't think the floor pan should slow me down too much hoping it will only be a 1-2 hour fix is all.



Guys stay tuned. .... I should be getting to the bench in a little while but I need to finish some house chores first than am hoping to break out the air brush to paint a couple of engine parts.... ie..... fuel pump, fuel shut off valve and the tee fittings. will post pics of them when I get them done.
