Printing Examples... show your best printing projects here!

[Dave White]

I just thought that this board might get a little messy if everyone starts posting examples of their print projects in separate topics... So, how about adding your pictures, files and links here.

So to kick off here's my contribution.

I've had our school's machine up and running for about a week now and I've spent most of my half term holiday trying to get to grips with the subtleties of skeinforge, temperatures, speeds, fills, carve, raft, etc. whilst trying not to blow out my ptfe or mash the extruder into the baseplate  
I think I'm now in a position to be able to show our students at school how they can print their own designs from Pro/ENGINEER.
I did have some problems with the stl files from Pro/E (until I realised that ascii versions worked and the binary ones don't) so I searched around for some examples to print on the interweb thingy as those minimugs get a bit dull after a time... I came across these at http://www.thingiverse.com/thing:413. I couldn't resist the challenge, so here's my attempt.... not bad for a newbie and yes the 2 parts do screw together
Anyway, I hope to be able to post some examples from the students soon.

A colleague challenged me to make a Klein bottle.
It was quite hard to design using Blender, and took some tweaking to modify the design to make it printable, by eliminating shallow angles. The photo taken during building shows that I didn't get the base quite right, the angle was too shallow and the filaments only just held together.

Dave,

inspired by your photos I printed the same - it's lovely! And it prints very well. My kids love it, and I've made three copies now to keep them all happy!

Brian - great object! Do you have the stl file - I'd like to try it.

Mike.

Here is the blender and stl for the Klein bottle. I'd suggest thickening the top half of the bottle, and the base definitely needs attention - it is too shallow. My Blender skills aren't very advanced - I had to get my Son to create it. I'll ask him to improve the file and then repost it.

[mike]

Thanks. I haven't used blender - might use this as an opportunity to take a look. Although do post a link when you have one you are happy with!

not best - but one I'm most proud of .. sphere, no support, PP, room temperature, hand tweaked g-code (extrusion rate, temperature)



there's a pic during printing there on the album

[Dave White]

WOW

Well done Bogan, very impressive, you are right to be proud of of that one.

it is tweaked g-code but still does not print every time ... somewhere around 95% (one "fin" is done, ~2mm before the top of second "fin") it is extremly fragile and in 50% cases detach from raft ... if that object is usable and not easy noticeable that 2mm on the top is missing

all in all, printing sphere without some support is possible (as you can see) but not really recommended ... I did it as a test .. and because mine skeinforge for some reason do not want to turn on the "support material"

it would also be cool if skeinforge could automatically reduce the extruder speed when printed area is small.. for now, thanks to Tony's 1.0.5beta one can do it manually

[Ian]

The latest skeinforge has the support working and also has cross hatch for the support and different flowrates on the filament.

[Bogdan Kecman]

I see the option (both cross hatch and support material) but when I change it and save it returns to "no support material" (it save the cross hatch - not sure what it does) ...

The skeinforge from jun18th (today) - works ok with support - testing now

I have an apple, it can be made without any overhang... Too bad I dont have any quality pictures because I had a small error with the Y-axis coming loose while building the apple.

The source files are on thingiverse.com if you are interested.

the first finished product that uses RM parts:



there are feet, the corner caps and the lcd mask all made out of PP.

[Dave White]

Go Bogdan!!! great to see som 3D prints being used for REAL uses.

Brilliant, it looks really interesting/technical.... what does it do though!

Thanks Dave, does not do much, it is soldering iron "base" for HAKKO soldering pens / handles. I have one rework station (soldering pen + hot air gun) and had few pen's spare so made another electronics box not to have to change tip's often (as I often need both needle point and "fat" tip during the same build). On top there is a led showing if heater is on, lcd display info on current temperature, target temperature and some other data (iron is disconnected on the pic so reading is funny), 3 pushbuttons for up/down/menu, on/off switch with red led and connector for the soldering iron. The box is made out of 3mm lesonit (the stuff they make back of the closet from), edges are alu profile 1x1cm... the box is 15x15cm (big 220V -> 24V 6VA, 6V 1VA torus transformer inside)

The top corner "balls" will not stay, those were really a "can this be printed" experiment, I already made new ones (cube-cube instead sphere-cube) that will replace them.
