3D Printing - "It's all about design and quality output. Not how fast the printer can run."
Thoughts on Resin 3D Printers
I have been investigating (on the Internet) photosensitive resin 3D printers. This includes the SLA (Stereo Lithographic Apparatus) that uses a deflected UV laser beam and the DLP (Digital Light Processing) that uses a projected full frame picture exposure.
I am not going into a tutorial about these two main types. There is plenty written elsewhere to those interested enough to search it out. (That is what the Internet is good at providing.)
Cetus, you know how to read G-Code quite well. You earn another, “I’m impressed!”
The Cetus native operating software does a very nice job of 3D printing. However, it is a proprietary system. The user must run it the way Cetus built it. Variables are limited so operating options are also limited. I want to run a print without a raft. I can, but Cetus will add a bottom layer and a skirt I don’t need or want. It can’t be turned off. If I want supports, there are a few tweaks available, but not something like “from the bed only”.
There is a work-around. The Cetus team has taught their controller program to read G-Code to create a print from other slicer /control software such as Cura or Simplify3D
New Cetus 3D Extruder
Latest word on the Cetus 3D is they are “messin’ ‘round” with a new extruder design. My extruder has been working great, so I am not certain what they are trying to improve. Perhaps cost.
I do know they have already changed the design of their nozzle. I received three 0.40 MM nozzles and they have an extended PTFE tube sticking out the top end. They are supposed to be a nozzle design change to fit the new extruder but can be adapted for use with the style extruder I have.
A Time Waster?
I spend a lot of my time working on 3D printing. I may be spending too much time. The actual printing is a hands off do nothing period. The printer just runs and does its thing. The waster is watching it do its thing.
With three printers, I switch between them. I often have all three running at the same time. That’s melting a lot of filament per hour. Each print normally takes hours to run. That means there is a lot of down time not doing anything with the active printing.
I use that time working on the CAD or drawing portion of the creative process. I have often said the printing process itself is not a profession. Operating the printer is a low to medium skill job, that has to be done, but I don’t suggest it as a career.
Cetus Nozzles (with updates)
Right now they seem to be made from pure unobtainium. They are made in three sizes. 0.2mm, 0.4mm and 0.6mm. One of each comes with a new printer. I ordered a spare 0.2mm and 0.4mm nozzle as part of my printer order on October 13, 2017. That is now almost a month ago.
