But the general printers started out as tractor feed dot-matrix giants. It has taken 30 years for them to reach the point of combination, color/fax/scanner/copier that conveniently sits without taking up 4 square feet. The 3D printers are hitting that area after only 5-10 years right now. It will be interesting to see in 10 years when someone goes "Wow, you really started out with an Ender3?"

My Anycubic Photon is in the attached garage and even then my wife “claims” it stinks in the house when I run it.

 

(funny she can’t smell  the large quantities of bleach she uses to clean the house <_< )

Depending on the printer setup, some of them come with their own filters now. You'll need gloves, safety classes, and a face mask. An ultrasonic cleaner and some 91% or higher alcohol to clean your printers plus a UV light source.

I know the photon has a filter on the exhaust port, but without a fully vented enclosure I can't see how you're going to avoid the smells. 

 

For post production cleaning I use metho and a dunk and swish method, mainly because of space I haven't set the Ultrasonic Cleaner up yet - as to a UV light source, I find the sun works well for post-curing ;-)

I really don't get why 3D printers can't be nearly as general-public friendly as regular printers have been for decades...

 

One day they will be...and some are getting close, you just need someone to develop a nice cartridge model of refilling the build material and we're looking good. For example, with the Photon my process for printing is to fill the print vat, insert USB with sliced file, and hit print. After printing it's clean the build plate, filter the unused resin back into the bottle and clean the vat. In that sense the resin printer is a lot more user-friendly than the FDM printer, but even my FDM printers only get the build plate levelled once every few months...

The smell is very different, her smell receptors are probably burned out to the bleach ;-) - but I would suggest investigating the 'low odour' resins that are out there...

Exciting.  Post results.

Easy set up my broccoli.

 

Easy if they don't wrap the cable from the print head around the base of the frame.  This means that the bed can't go all of the way back.  Which means that I needed to rewire it as the print head will not fit between the frame and the print bed.  Good for me that re-wiring and fixing cables is literally my job.  Though two of my cable lables fell off so I had to guess where they went going back in.  Smoke test was sat upon power up.  Will have to see what happens when I heat the extruder.

My wife is the same way. Bring in a primered mini or spray painted model part & she is "That stinks!". Cleaning,  not a problem.

 

So my PCs are gonna encounter some awakened trees. I have the files, I just need to get my printer (ender3) going again. This may be the motivation I need. I see down the road they'll face 2 Bone Nagas. Prepainted BN are e expensive (30+ per st least). Yah again motivation!

Note if you print the dog test file with the starter filament, it wont print all the way. Choose the squirrel chess pieces.

I'm eyeing a resin printer for Christmas. Anybody here with any experience? Is it safe to operate the printer in my office or do I have to keep the windows open all the time?

 

My Eelegoo Mars was very odor free... until I took the cover off to remove the prints. I've got in the basement and had no complaints during the 4.5 hour test job. Haven't printed anything else yet, but that's still getting the details put into the CAD models.

 

Caveat is that I'm part Harkonnen, so my chemical resistance is pretty high.

Squirrel knight chess piece printed fine.  So looks like my leveling is good enough.  I like the magnetic heated bed.  I can pull the maginetic mat off and peel it away from the print easily enough.  Now to start the search for files to print.  I have the basic dragon lock set from Fat Dragon Games from somewhere (Bones KS reward?) so I'll most likely start with that.

And yet, the distaff side has no problem with nail polish remover that has the full strength version of the volatile elements used in lacquer base paints.

Could you do some work in progress postings of those?

I think we both supported the same KS and I haven't received the printer I sponsored at the same time yet.  But the printer is very close to production and fulfillment as I write this.

Seems that when you change one spec. a lot of other things have to be rejiggered as well, near ad-infinitum.

The DragonLock files print pretty nicely (I have a few), in terms of finding files to print, thingiverse is a good starting point, but there are many, many more sites out there - if you are after military vehicles (ww1-> modern) Wargaming3D also has a good range.

 

It really depends what you are looking for!

About resin printers...   

Yeah, it can stink, and it's probably not too good for you, either.   

 

I don't know the Photon, but haven't heard anything bad about it. 

 

Mine's a Kudo3D Bean (build area 60x120x160mm ) but Kudo3D also have larger ones. 

Their HD version of their Titan 2 has an X/Y resolution of 12/25uM.   My Bean only does 47/47uM...

That's what you can do with a HD printer. 

Unfortunately, I can't recommend them at this moment because their support is currently like a mermaid's legs; a myth on a myth...    

 

I have 2 resin vats for my printer. Not just because it allows me to change between different resins from one print to another, but also because they have a Teflon film as the bottom, and that is not only a pain to replace, but gets damaged way to easily. 

 

If your Resin printer have similar vats, get a stack of films and learn to replace them.    

 

I don't pour the resin back in the vat immediately. If I don't plan to print something for a few days, then yes, I do it. 

And when I do pour it back, I use a disposable filter of the type used by spray painters to filter their paints. (similar to coffee machine filters in size)   

And I splash the resin around a bit with the rubber scraper after a print to find loose bits of support and so on. Because if that ends up under the print ed before the first layer of a print, it will probably damage the film, or even the LCD in the printer.

All of this, very, very much! I have a very similar process after a print. What I have found with leaving resin in the vat is that capillary action means that the resin actually leaks out of the vat after a few days - and because even if I plan to print in a day or so this doesn't always happen due to other commitments.

 

I have also found with pigmented resins that the pigment settles in the vat - and in fact the only time I've had failed prints in when this has occurred.

 

In terms of resin, most printers will work quite happily with any resin that cures at the right range, so you aren't limited to only the resin made by the manufacturer of the printer. For me this is good because there is a local resin manufacturer that sells suitable resin which means I'm not relying on ebay and aliexpress to get resin - and it's normally here within a week.
