hello all, i designed and printed a ring saw. took about 8hr for the bottom print, 4hrs for the side sections, 1hrs for the arbor guides, and 2hrs each for the coil guides. (around 20hrs total with clean up and setup) i have not yet used the machine i still need to make the blade arbor. i installed a arbor from one of my other machines for these pics. and as you can see it don't fit right.






cost:

ball barrings $0.80
ABS Plastic Filament $5.00
8mm Threded Rods 125mm x4 $4.00
8mm Nuts $0.05 needed 8 0.40
5-40 socetcap machine screws pc100 $5.00 (needed 16 0.80)
5-40 nuts pc100 $3.00 (needed 16 0.4Uber
sub total: $18.20 (11.4Uber
estimated Arbor ~$20.00
Blade ~$10.00
total cost of build: $48.20 (31.4Uber

on to testing.

RESULTS ARE GOOD, some minor changes needed.

Need to use a larger blade designed for a 1.5 and i only had a 1.25 on hand. so i could only cut some 20g. but it cut well.

Simplification of model: i'm removing the need for the barring holders as separate parts and butting them directly into the side sections. just saves printing time and build mats. will function the same.

Trimming some fat: i made it a bit beefy at first. did not know how sturdy the print would be. and it was vary stiff even with out the support bars in place. i trimed the walls to 3mm (from 6) and the struts to 10mm(from 12). this will cut about 48% off build times and not effect machine when assembled.

designed a printable arbor now as well. hope it will work well too.

printing the second revision now.

selling one: once i get it perfect then i will think about possibly selling one or two.

going to print the arbor and new body tonight but here is the new plates. they came out a bit rough i was having ishues with the temp on the printer.

Careful here Smile I'm interested in the idea as well, but we're bordering on Trading Room material conversations...

Curious what ring sizes you're aiming this cutter for.

You're printing the blade arbor too? Have you done any tests on its long term durability and strength? I would think for cutting hard materials it will either break or wear out of concentricity very quickly. Even for aluminum I don't see any plastic arbor lasting very long. One thing an arbor needs to do is dissipate heat from cutting and revolving friction. At 1000+ RPM all I see is the plastic arbor melting and welding itself to the arbor guide.

Daemon_Lotos: every thing from 1/8id 24awg on up to 8swg 3/4id it should do. there is about 1.5in space avalible in the guide section.

affinityofmist: its not a 100% plastic just the blade guides. rest is metal. you could think of it as a washer setup. but it more stable then that. when i get it off the printer you'll know what i mean.

Zlosk: I'm using a Prusa Mendal. see: http://reprap.org/wiki/RepRap_Options
i've done alot of minor changes so it works better then when i got it.
some adjustemts i've done:
*increased build space Z by 50mm, YX by 10mm
* removed the z stablizer barrings (unless you have vary true rods these make wobble worse)
*made new top vertexes to support new hight and to carry the spool holder.
*replaced the XL belts with GT2.
*replaced the stand off bead setup with a all in one heated aluminum platewith a borocilicate glass incert.
*using a Bowden drive feed for dual extrution heads (i only have one head atm)
*up graded electronics. using a Ramps1.4 Arduino setup with LCD/sd shield.
*replaced the Nema17s with Nema24s For x,y, and extruder.
*two 40mm fans, 1 120mm fan, and heat sinks for all motors.

okay back on this again. printed the new form, got to pick up the barrings in the AM and find some bolts/nuts (vitamins) for it to give it a test run.

changes, and why.

Made the over all size smaller. i chose to do this for printing reasons (total print time about 5 hours for all parts) and that the size first really is not needed for most ring work. on average you don't need to cut 2lb of 1" id ring. so i took the most common "max" size and used that 3/8 ID can fit up to 12 swg 3/8 rings. if you need them but it vary small machine, this has a back lash of making the liquid coolant tank much smaller. so a small pump to change out the coolant or more coolant changes will be required. i have placed a hole printed into the bottom of the machine body to drain the coolant if I get to using a pump.

still working on the arbor right now i'm using a printed guide on the blades + washers and slim bolts. this makes it a bit hard to change out. i will have a dual sided clamp system when i get over to turning one on the lathe. it works thou nice and stable.

There is no metal to Plastic contact other then the coils feed into it. so no worries there.

the two plates that the coils are guided down are made from fiber filled nylon. quite durable, but will need replaced from time to time, but at $1 - $2 a set that is not a big deal.

printed in YELLOW i hate yellow, all i have on hand atm thou. the section of filament are just to hold the guides in place for the pics, they need 50mm m5 bolts. that i need to go pic up yet.




Plastic used 37.15cm^3
$48 a Roll of filament 800cm^3 per roll
so about $2.23 of plastic cost
Electricity cost to run the machine about $1
tape $0.05
barrings 0.33 each ($0.66)
other vitamins ~$5.00
Blade $10
all in all under $20 so far.

things yet todo:
Mounting plate: it's not going to hold it self down..Razz
Motor Mount
Speed Controller
more later....
