Any 3D Gurus OUT THERE ?

[robbie2016]

Seems like theres lots of people looking for different frames to come out for their custom led setups. Not sure how many of you own a 3D printer, but these things make some pretty sturdy objects. If anyone out there is willing to design prints (STL format), I'm willing to print them out and be a guinea pig. Im about to put my LED set up together and was going to use standard angle irons. Much rather go with a cool design done by one of the community members.

I have a Makerbot Replicator X2, and I'm about to build my first 20 cob fixture.
I already printed a perfect heatsink out of ABS, and my friend will try to make a mould out of it so we can pour our own passive pin heatsinks in aluminium for like $0.50 each.
I had the idea for my light to design a modular system, which means that my design can be used for creating a fixture as big as you'd like and expand it later to fit your needs.
Currently I'm waiting for some parts to come in at the store, after I have all the parts I will adjust the designs I already have. Its going to be awesome And the best thing is, I'll make it open source

I have the same printer lol its great.

what do you mean by parts? Need more filament? Mind uploading a couple pics of the STL ? I'd love to see how it looks. I wish i was CAD savvy, i'd design my own frame as well.

 

[Strainhunters]

I will when its more finished, I'm still changing a lot of stuff like the connecting rods which connect 1 cob-holder to another to create 1 big fixture etc.

Take a look at SketchUp on youtube for cad software, its super easy!

I'll be watching this closely! Looks very intriguing.

Can i ask you guys ,how much for one of these 3d printers used vs new .and is it worth getting a used one or maybe what to stay away from?

You could get a small one for a few hundred but the build plate will be 4" max There are a lot of different features and filaments you can use. Not all filaments are interchangeable. Its going to be a matter of preference on the features you want the build size type of material you can print plastic metal flexible wood pva to name a few.

 

[Strainhunters]

I use nylon filament for stronger parts, had to get a special nozzle for it and use a heated build plate.

Also have ninjaflex, a rubber-like filament. Can be used to print wheels for an RC car for example.

Mainly I use ABS tho, its strong, cheap, and comes in lots of colors (even transluscent). ABS is the same material as LEGO.

Im designing a cob holder now so I can print my own if I need them.

Recently I printed out a bunch of hard 90 degree bend tube to connect hoses too. Im basicly making everything I need. From Grinders to weed shape cookie cutter shapes, watch straps, pollen presses etc.

I also have a desktop cnc machine (cheap one) but with watercooled spindle to cut aluminium and steel. Hobby's...

would cast aluminum have similar thermal performance to cold forged?

I dont know mate, I think alot also depends on the type of aluminium used for the cast. This will be an experiment, might work - might not

I'd love to find a 3D printer big enough to print out SIPS bucket designs.

Any 3d printer can do that, even if the build plate is not big enough.
There is software available with a so called "slicer" function, which cuts up a design into pieces which fit on the build plate.
You'll need good glue tho

I've printed a big part like this in ABS filament. ABS filament can be "welded" together with the use of acetone.

 

[wietefras]

Isn't it a whole lot easier to buy some aluminium angles and screw that together rather than 3D printing coners/braces for the frame?

I'm a big fan of 3D printing, but for the frame I just don't see that being easier or quicker.

Related to cannabis growing, I printed a fan shroud (squirrel cage fan to round exhaust), corners for a scrog net clipping on tent poles, funnels for filling my vape straight from the grinder, custom bulkheads etc.

is that what ABS pipe glue is?

not necessarily. you can slip fit a rack kit with molded connector corners together in your living room in 5 min. not everyone has a drill (or should be using one)

You and me need to talk, bro.

@CobKits, You will also spend days designing and printing those connector pieces. Or if it's a kit built, it could be pre-drilled a lot faster/cheaper.

Or use self tapping screws.

I saw a frame designed from square aluminum tubing with friction connectors. It was quite clearly bending at the joints. That would irk me too.

Or the fear of these friction things coming undone when you pick up the frame. I'd drive a screw in there anyway.

Dunno. As I said, I love 3D printing, but I'm not really seeing this one.

Although I'm designing custom channels to clip on a water cooled frame to hide and protect the wiring. Which could probably just as well be done with tape.

I feel you, but for me personally there is also that optical / design factor what's important to me. CNC/3D printing/designing is a hobby, as well as growing plants, so I combine them and take my time untill I'm satisfied with the result.

A frame could basically be made from pieces of scrap wood and a couple of screws or any other other materials you might have kept around in your garage, so even the purchase of sheet metal or metal profiles is not entirely justified, but where's the fun in that approach?

Besides the eye-candy-factor it's also nice to include cable guides, bolt holes, etc. in one printed design so there is no fiddling around with different parts. I just design it where I want it

En zoals ik al zei, het oog wil ook wat

new to here but always willing to help...if you have a rough idea of what you want I can model it in Autocad 3D for you and export the correct file to be printed...let me know and we can work something out!

And like you say, it also counts.
