3d Printed undercurrent Hydroponics system (UC RDWC)

Decided to attempt a 3d Printed undercurrent Hydroponics system (UC RDWC) , as they are very good systems but just cost a stupid amount of money. It seems that things like the large tank connectors realy drive to cost up.

i also seem to have collected a lot of filament that i can use to print most parts except the 110mm pipes and the quality square buckets i found.
PETG fillement costs about £15/16 for 1kg and can print 2-3 massive fittings for that if not more.

im printing :

110mm/111mm tank conectors threded with tpu seal
110/111mm reducing tee with 1inch bsp threaed with extra drain hole for drain and cleaning the system
1inch bsp filter and filter incerts
a filter extender
net pots
110mm/111mm equal tee solvent weald
110mm/111mm equal tee threaded
110mm/111mm blanks for end
110mm pipe filter / catcher

A venturi jet pump willrun the whole system hopfully , the air is used to move water around the system while also adding dissolved air into the water. one air pump reduces the running costs. currently 110mm but might reduce down to 1inch pipe also but a work in progress as figured larger pipe might help with flow.

Do you have a layout sketched for configuration of components? If so, may I please ask you to post it? Can you post links to any threads you reference or other info about this type of system?

based on the
Current Culture H2O - Hydroponic Cultivation Solutions

type system basically configured like they have it 2 tank connectors on each bucket and then connected to each other ...you can connect in a circle and use the reducing tee to connect to your water pump and filter that pumps back to the filling bucket ... you need to have everything in parallel to keep the flow equal and balanced

jet pump design coming on reduced its size so inlet and outlet is 36mm pipe and will try 3 connected together which should increase the pressure and push the water faster

What's going on inside there? Is that a passive system or does a mechanical pump attach somewhere? What are you using to CAD that?

no moving parts uses an air pump for the motive and to generate suction to pump the liquid this also dissolves air into the water i did also think you could add them between the pots to generate a greater current ... also can be used to mix nutrients into the system the therory is sound just need to get it working with a reular air pump ... if it dosnt will prob use an airlift pump design
using fushion 360

starting to take shape just need to print the rest of it and a non-return valve for the inlet and will be ready for the test

36mm check valve design done using a tpu flap

can you share the .stl files?

How did it work out?

Post the files!

What a tease. Posts images of parts he designed but not the stl files!

Covid probably got him.
