I have designed a delta and am ordering materials for the build. It has 300mm printable bed and 1 meter uprights. The uprights are 2080 v-slots to give maximum carriage stability, 100 mm rod spacing and lateral strength. I did not want any of the frame to be printed, to maintain rigidity and maximum strength, so I am using 1/4" top and bottom plates and around the base plate more 2080 extrusion that will bolt to the uprights and the plate to give vertical stability. They will be cut on my 10" miter saw. They do not have to be machined as the will be tightened into place once the fame and bottom plate are squared up. I will be fabricating the bed and plates and have the aluminum. Right now I am trying to decide if its worth my time to build my own magnetic rods or buy them. If I get them custom made they are $125, but the standard sizes are not quite right for my printer. I calculate I need 334 mm arms. Any suggestions are appreciated.

After posting my design I got quite a bit of feed back. With that input I modified my design slightly going from 100mm rod spacing to 80 mm. I reduced the size of the verticals from 2080 to 2060. I have one piece of .25 aluminum 24" x24" for the top and bottom plates, a 13 x 13" .25 plate for the heated bed. From some left over .125 scrap I am making my carriage plates. I intend to do all of this build without outside machining or cutting.
The carriage plates were cut with a jig saw and then filed to final dimensions. The outside shape isn't critical. but the mounting holes for the magnetic balls and the wheels must be very accurate. So I built jigs for those plates and once the outside dimensions are close enough, I put the plates into the jug and drill.075 pilot holes for each hole. I will then drill the pilots out to the required hole size for each location.

More pictures. The jig is printed so the hole guides are 3/4" deep and they will each only drill 3 holes so accuracy should stay very close.

Slowly getting parts completed. The effector is now rough cut. I have the pattern glued to the heated bed .25" plate. My inside and outside carriage plates are done and the belt couplers are already to install on them. Got my v-slot order yesterday.

My design is somewhat unusual as I have the main carriage going up and down on the exterior of the machine. So I have a large carriage plate outside and a much smaller carriage plate inside to connect the rods. This allows the effector to move without hitting belts or the carriage. The picture shows the inside and smaller plates next to the couplers for the outside and larger plates.
Got the bottom plate finished.
Got the bottom plate finished.

So I have been using something simillar for a while. Although I got my frame laser cut in steel for around USD 7.34 which included the price of the steel. Attaching the photo of the printer

Hi Prateek,
I just came across this post and I am trying to get an aluminum heat bed for my delta printer. Was wondering where did you get your heat bed in India?
Thanks,
Balaji

@balajiramani
you can always make a a custom bed easily. Use nichrome wire ( available with all electronics/electrical shops) embedded in liquid silicone gasket( available at all vehicle spare shops). or u can use silicone blanket heating wire taped to the bottom with polymide tape. Calculate the resistance according to the voltage and wattage needed. All my custom printers use silcone blanket wire and it works just fine.
