How to transform an Ender 3 in a set of open, easily programmable syringe pumps set.
Syringe pumps can be quite expensive, and with limited possibility of automation. For solving this problem, we bough a cheap Ender 3 and repurpose it in a set of 3 syringe pumps.
Almost everything needed for the build is in the box, even all the screws and the tools you need for assembly the syringe pumps.
The programming is as simple as writing a text file (gcode) and works out-of-the-box with the Ender 3 motherboard already flashed with Marlin software.
The project is Open Hardware, all the details, the 3D files and instructions are in the preprint and the GitHub (link below)

That's wonderful Vittorio. This is Rahat from MKK lab. This detailed instructions will be very helpful during the experiment

Hello from India. Firstly, a great video... and such amazing creativity... wow! I'm a doctor, and I'm also associated with an NGO here. Was planning on donating an infusion pump for a long time now... but it was too costly. If anyone is interested in selling one of these to me, I'd love to connect with them to discuss further details. Thanks. 👍🏻😊

That's amazing. Thanks a lot for the detailed instructions!. It is so kind of you that you share that experience! Congratulations!

@v_saggiomo 3 года назад

thanks :) let me know if you build a set

@raniersepulveda4626 Год назад

We are building one right now. Thanks for sharing.

Very creative got your idea working using off the shelf parts.

Awesome stuff my man!

Thank you for the great work. Wondering if you can use different syringe volumes in different channels at the same time? Do you have an example on this? Cheers!

@v_saggiomo 2 года назад

Yes, it is possible to use different syringes on different pumps, you just need to change the M92 commands, and yes it is possible to use different flow rates for each channel. From our paper: ________ Multiple syringes can be used at the same time: G1 X0.5 Y0.5 Z0.5 F1 Will deliver, at the same time, 0.5 mL of liquid from the pumps on X, Y, and Z at a speed of 1 mL/min For using different flow speed for different pumps, the total amount of liquid should be calculated taking in account that all the pumps will reach the end at the same time. For example: G1 X2 Y1 Z2 F1 Will deliver the set amount of liquid at different flow speed, using 1 mL/min on Y, and 2 mL/min on X and Z. __________

Can you tell me how could you manage to view those droplets using cell phone.? Looking for such a unique model for my microfluidics work. You knocked it. Thankyou so much.

@v_saggiomo 3 года назад

this is quite a "big" microfluidic device (1mm) so the flow is quite slow and ca be recorded at 30fps without any problem

@ashwinkumarnarasimhan4604 2 года назад

Hey.. thankyou so much for the information. 1mm is the channel dimensions.? Also how do you program to set for 10uL/min.? I mean the G-Code.

@v_saggiomo 2 года назад

@@ashwinkumarnarasimhan4604 yes, 1mm channel dimension. The gcode for 10uL/min would be something like G1 X1 F0.010 F is the speed in mL/min. but better read the GitHub and the preprint for a better explanation: github.com/Vsaggiomo/Ender3-syringe-pumps

@markgrayson4460 Год назад

Curious can this be used to fill the syringes? Possibly with a thicker fluid or even grease or paste?

@v_saggiomo Год назад

Withdraw yes, that’s possible. Paste and thick liquids I guess not as the motors are not that powerful

@phoema80 Год назад

Ciao Vittorio, credi che il tuo approccio possa essere usato invece per fare una stampante con siringa? usare i controlly della stampante per un motore NEMA17 o bisogna riprogrammare la stampante?

@v_saggiomo Год назад

sicuramente, ci sono gia' vari modelli in giro. Il piu' semplice è quello di usare l'extruder motor come syringe pump: www.biorxiv.org/content/10.1101/2021.03.10.434735v3.full.pdf ma ci sono anche modelli piu' complessi dove la siringa sta direttamente sopra il printhead: www.hardware-x.com/article/S2468-0672(17)30082-2/fulltext www.hardware-x.com/article/S2468-0672(18)30087-7/fulltext cerca "bioprinters"

Hey, recently I tried to build the pumps using the dual+50ml adapters, but the holes for the rod are not aligned, is there any fix exept making holes in the 3d printed parts?

@v_saggiomo 4 месяца назад

it'a a standard Ender 3? we (and other groups have rebuild it without any problem), are you sure you are using the right axis? can you drop me an email with some pictures?

@karelchramosta1378 4 месяца назад

@@v_saggiomo there is no problem with bought parts, I sent you an email with photos of the problem.

@rover1102 10 месяцев назад

Would this work on an ender 5?

@v_saggiomo 10 месяцев назад

well, yes in general terms (programming, motor steps and so on), not sure if the 3D printed adapted parts are the same

@fikretkus106 11 месяцев назад

I really don't understand. Did you really waste the whole 3D printer to make a syringe pump?

@v_saggiomo 11 месяцев назад

yup, a single syringe pump costs 400€, this 3d printer costs 150€ and you can make 4 syringe pumps...

@fikretkus106 11 месяцев назад

@@v_saggiomo Thank you for your kind reply. I've got your point but still you don't need to waste the printer. All you need a NEMA 17 step motor, 2 steel rod, 2 lmek 08 uu linear bearing, 2 8mm bearing, a motor coupler, a lead screw with its nut and the arduino. The other parts could be printed. All of them takes 28.27 € acoording to prices in Turkey. I tried it and it works fine. By the way 400 € looks like a good price :) I can deliver hundreds of them for 200€ with a high quality metal parts and touch screen :)

@v_saggiomo 11 месяцев назад

yes, of course you can, but that's not the point. The point is that in a single box you have everything for making them
