/diy/ - Do It Yourself

>what went wrong, though?
Let's list off all the failures that each one of these printers has had over the past month.

Teflon liner in extruder getting pinched or distorted at the top end causing underextrusion due to friction.

Buildtak wearing out and needing replacement.

PEI not being a viable substitute because it's expensive and only last a month. After which time parts no longer get bed adhesion.

The cleats inside the push-lock fittings coming loose and getting fed into the extruder (clogging it).

The teflon tubing coming loose from the fitting on the extruder end, causing any further extrusion to just unwind the spool above the printer.

Other causes of nozzle clogging.

gcode on the sd cards getting corrupted causing a layer-shift mid-print.

The foil wrap and insulation on the hot end coming loose and getting absorbed by the print.

Earlier firmware on one printer not liking the filament preheat prior to selecting a print. Causes the print to take 20 minutes to start if I forget to turn off the preheat after swapping filament.

And some of the above issues even showed up on the brand new one I bought right after taking it out of the box. So my 4th one is getting returned.

I am asking too much of these cheap printers. I am printing 18 hours a day, 7 days a week.

I started off making them under the premise of casting them myself and even that was becoming too much of an investment AND too labor-intensive to do.

I don't have thousands of preorders to provide the startup capital to afford injection-molding.

With 6 printers I will be able to produce 2 to 3 whole blasters per day plus a few accessory prints in-between. After some small revisions 80% of the parts can now be printed on a 120mm build area so if I need to scale production up at some point I can just buy another monoprice select mini.

The hobby is way way larger than it used to be, but what I'm selling is still somewhat niche, I don't live in Singapore, and I'm trying to do this entirely on my own. My workspaces are a single closet full of printers, and office for assembly, and a shed where I cut all the hardware sets to length.
