Build is complete
Special thanks to dddman for the printed parts to get me running.
Here are some pics

The completed printer


After giving the printer to my little princess, look out she has a frog army!

Excellent work Robert.

Tweakie.

 

Ty bud!

Here's my custom heatbed I designed in sketchup, milled and then added a layer of cork then aluminum tape as a insulating layer in attempt to have a faster heating time

 

Forgive my ignorance but is what I am seeing above a copper coated board (circuit board blank if you will) milled to create the heat "grid". Then backed with cork and covered with aluminum tape?

Does the copper "circuit" have the required resistance to generate the heat required for the bed?

 

Yes and yes again
It's resistance is 3.5 ohms
This is simply an experiment in hopes of good results

 

Very nice. I will be watching to see your results. I need a larger size bed for a project and anything over 12" x 12" starts getting pretty expensive. Copper clad board can be be found pretty darn cheap and I could see a scenario where linking several boards together would be easy.

Did you use 1oz or 2oz board for your design above?
I assume your are putting a sheet of Borosilicate on top of the exposed copper grid. Is that correct?

Keep up the good work!

 

Not sure of the oz count as I picked up the clad as you said cheep at my local surplus.
$16 for a 300x300 sheet
I will be putting regular temped glass or mirror, will see what the glass cutter three doors down has on hand

 

Here it is for now, mounted with tempered glass

 

Looks great cant wait to hear how the heated build plate works

 

The frame files are done

 

I'm assembling and wiring the OBi3 now

I just finished the mechanical part of the build last night.
Will be testing real soon

 

Hey guys very excited to get my build going thanks again Robert for cutting the frame plates for me. Any idea when a parts list will be up excited to get all the goodies together!

 

dddman great man thanks the prints coming off this printer are looking great

 

No prob
Frame is packed and ready to ship
I really like the Blue

I also picked up a neon orange that glows real bright when the light hits it

 

Awesome cant wait to get to building it!

 

Here are a few pics of the parts I'm printing for others

 

Parts look amazing man!! My friend is printing me the parts now but under the file tab i dont see the main extruder part. the one printed in blue on your post. Any help would be appreciated

 

Be sure to use net fab to fix the error in the stl from thingverse

 

Have you guys seen this might be a nice thing to add to the printer

if it works like i have seen in youtube videos it will get rid of what i think is the hardest part of 3d printing

 

A neat idea indeed @Mopar32985 thanks for sharing.

Tweakie.

 

Ready for tuning and testing


Stay tuned for the heatbed results lol
