Mimaki 3D printed replacement parts

[Forty One]

Thought I might start a thread on 3D printed parts you might need for your Mimaki.
Mimaki HQ here wanted $150 ea for the fume extraction fittings. I had one of the original and thought I could atleast try to print it.
Here's the file. It should also accomodate any other machine with the extraction fan setup and accomodate a 100mm hose.

Hell yeah, thanks for sharing!

That's badass!! I think printer parts/accessories is just about the only excuse I have to get a 3D printer, lol.

I thought you were going to use a mimaki 3d printer to produce replacement parts for other equipment, was wondering why anyone would waste such expensive ink to... oh.
Very cool, glad some folks aren't afraid to put their 3d printers to real world use!

I've uploaded a revised design of the 90 deg elbow. This will accomodate a 100mm ID PVC pipe and will attach to my next design of a T piece for the other outlet.

Note that the fan ducts on the back of most Mimaki printers is actually intended to blow down/into the printer, not to extract air/fumes. I think the UJF series is the main exception. Had to deal with some weirdness from people trying to strap fume extractors on the back of CJV's as a result. The right application is shown, but just for people in the future.

Not on the JV33. these fans blow outwards. There would be no benifit in blowing onto unprinted media.
The place where I got these printers from had the fume extraction system set up as such.

Yup, depends on the model, printers like the UCJV just have the ports due to sharing a 'universal' frame.

Mind elaborating on that a bit? I've consider adding fume extraction to our UCJV / Epson printers but not super excited about cutting holes in them, and always wondered what that air flow would do in terms of static / ink spray etc.

Thanks!

The Epson exhausts the air along the entire back of the printer, I have an exhaust fan behind the printer, but it's not connected to the printer, It definitely helps, but I can still smell it during heavy print days.

Pretty much comes down to experimentation. The fans on some printers are optional for helping dry ink in addition to the heaters. The air feeds in back of printer and Low velocity fans should be fine to extract fumes, but remember, in the case of the UCJV with the front cover, it will want to pull are from the edge right next to where the printing happens. Flow is everything, want enough to move air out, but not enough to disrupt the fine droplets from the head. Basically avoid using high velocity/high volume fans and blowers and pay attention to possible print quality changes.

Diagram below is for the blower on the CJV150/300, the deflector (13) is there to redirect the flow downwards. These are simple blocked off with a plate (3) on the UCJV300/150.

Thanks for this awesome contribution. I'm so impressed by this.

With the UJF 7151, it's not recommended to attach an extractor to the back as the airflow could effect the print.
I installed a vent above the printer and ran the extraction that way. Has done away with the majority of the fumes, but could be better.
As I go through and fix up the entire extraction system here, I'll probably add another vent and add another fan.
I mean, it only takes 16hrs to print a fitting...
