    are the 3d printers ready for prime time?

    looking for one that won't blow Santa's budget.

    contemplating this one.  https://smile.amazon.com/Function-Extruder-Precision-Printing-9-1x5-9x5-9/dp/B076BLQWHY

    it says dual extrude, that's good right?

    has anyone 3d printed the dragon3 or mildragon?

    As you can see by the answers above, I think the answer's a resounding "yes", they're ready for prime time. wink

    As to what printer to buy? Like computers or programs, it all depends on your needs. All have Pros and Cons. For any printer you're interested in, take a little time and you'll find lots of video review and it's worth the time to watch some of them. There's so much free knowledge out there, it's amazing.

    As pointed out above, resin-based printers deliver the highest quality of print, but the materieals are much more expensive, they're messier, and hae a lower print volume. If you're focused on gaming miniatures, they'll deliver the best overall quality, thoush as someone pointed out many users of FDM printers can achieve very, very similar results. A lot of issues with layer lines is eliminated with priming and painting.

    You don't need a solvent with PLA -- some people use it as a mist to smooth out the outer layer to give it a smooth, glossy finish similar to the look of resin, but that's a small percentage of the users.

    I jumped into 3D printing only 14 months ago; at the time, a resin printer was a no-go -- I don't have a print area condusive to it (no room for handling the chemicals or disposal and no room with adequate ventilation) and the toxicitiy of the fumes would no doubt have done my wife in. The smells from an FDM printer are minimal (and often pleasant) and while there are very fine micro particles emitted while printing, I have a desktop ionizer/air purifier sitting between the printers that hopefully takes care of that. Had the plant-bsed resins that Petercat mentioned been around, I might have drifted that way but probably still would have gone with the FDM printers simply because of material cost and print volume. WHile most of what I print stays within the resin-base print volumes, I am finding more and more uses for larger things. I'm currently printing 12" x 12" 2-colour privacy panels for some of our sunroom windows; I'm printing them 0.9 mm thick in translucent colours and the cost of a panel is under $2 each, cheaper than buying rolls of vinyl covering.

    Besides print volume, there is a large variety of materials available, should you ever decide you wanted to try something different, like PLA with wood or metal partcles infused in them, flexible materials like TPU, and so on. The printer you mentioned has dual-extruders, which allows you to either mix colours or materials. By using PLA for your model, for example, you can use the other extruder for your supports using PVA or PETG. PVA is water soluble, but expensive and eliminates the need for support removal and greatly reduces (if not eliminates) the need for sanding. PETG is roughly the same price as PLA and doesn't stick well to PLA, so your supports will pop off fairly cleanly.

    As mentioned above, auto-levelling is nice (very, very nice), depending on implemenation, but while very convenient, it's not a deal-braker for me. My first printer was an AnyCubic i3 Mega, without auto-levelling, but taking a couplel of minutes every 10-20 prints to level it isn't too bad. My second printer was an MP Mini-Delta (I'm fascinated by the Deltas) and it auto-levels everytime it starts a print. Despite it being the noisiest and smallest of my printers, as long as something fits in it's print volume I actually use it the most for small, quick prints. My wife bought it for me last Christmas for it's regular $239 (Canadian) and I liked it so much I bought another one this Christmas for myself when Amazon had a limited-time deal for $143 (Canadian). It has a 0.05 mm print resolution, and if you put on a smaller nozzle (e.g. 0.04 mm is the standard, but you can put on 0.01, 0.02, 0.03, etc.) and using 0.05 mm layer size while slowing the printer down, you can do some very fine miniature printing.

    My third printer, an FLSun-QQ, is a tall delta printer and the quietest I own. You autolevel it once when you set it up and it keeps that levelling in memeory (the print beds don't move on Delta printers, so once levelled they usually stay that way for quite a while, after whch you can auto-level it again).

    Something I find more important than auto-levelling is the finish on the print bed. Anycubic introduced their "Ultrabase" coating, which has a very fine mesh on top of the glass plate that expands when heated -- allowing the plastic to ooze into the "pores" and stick well -- and contracts when fully cooled (where the "pores" contract and push the plastic out, so prints lift off of the bed without any effort). Other printer manufacters have been coming out with similar beds and it's one thing I really look for. It's the one thing my Mini-Deltas are missing. I've never had to use glue stick, tape or hair spray on any of this type of printing bed. sad

    I had actually looked at the same printer as you this fall, but I started to lean towards this one instead:

    https://www.amazon.ca/GEEETECH-Mix-Color-Integrated-Break-resuming-255×255×255mm³/dp/B07K1FLZ9T/ref=sr_1_41?keywords=3d+printer&qid=1577335473&sr=8-41

    I'd planned on adding this (their equivalent to Anycubic's Ultrabase):

    https://www.amazon.ca/Geeetech-Superplate-Glass-Platform-235mmx235mmx4mm/dp/B07RXXYCP2/ref=sr_1_18?qid=1577370554&sr=8-18&srs=10038541011

    And this to give the printer auto-levelling:

    https://www.amazon.ca/Geeetech-Leveling-Precision-Improves-Printing/dp/B07RVMV8ZM/ref=sr_1_26?qid=1577370629&sr=8-26&srs=10038541011

    I thought that would check off all the "wants" on my list for a new 3D printer. I eventually opted for another path, but that's another story. wink

    I haven't printed the dragon per se, but I did print a test of the Dragonfolk the first week or two I started printing, image attached.

    As well, here's a few samples of things that show a bit of variety, like some Christmas Tealight holdes I made for Christmas gifts this year, and a couple of 6"-plus prints. The prints of the large, orange figures are just under 6" each (there's a 3" character for scale); what's important to note is that when I printed them, I printed four characters characters on the print bed at once, which really makes things easier.

    The white print is of my daughter, it's 7-inches tall and a quick, low-res print like this cost me under $1.50 (Canadian) to print. The low cost of PLA alllows me to do a lot of "playing" and experimenting.

    does ds print directly to the printer?

    does mudbox?

    like, what modeling software can print directly to the printer?

    my dayjob bought a 3d printer.  so excited.  dunno what make and model yet
    they deliberately torturing me.  been begging for one for years lol

    No

    No 

    None that I'm aware of.

    DS, and mudbox I assume, can produce OBJ files which then need to be run through a slicer program. That converts the OBJ file into g-code instructions for the 3d printer.

    Get a good slicer as getting infill, supports and bases right will save you lots of filament and heartache from failed prints.

    TBH I'm not a modeler and do all my printing from files produced by others. For me STL has always worked out better than OBJ but YMMV.

    Also 3d printing is not one of those things where you can toss the manual and figure it out. Read your printers manual and find any tutorials you can online. Even very small issues can completely prevent the printer from producing useful prints.

    if you are using an XYZ build up printer of any sort, the model needs to be put through a slicer, holes filled and supports added for overhanging mesh.

    Resin this is not an issue

    don't ever buy a DRM protected printer like me!

    even buying the genuine filament it did not identify the built in chip in the cartridge and won't work and their customer service basically told me to sod off

    I recently purchased a Creality FG 3d resin printer. This is a (bad) photo of the Bullywug converted to a 28mm scale figure printed for an upcoming game. The details are quite good.

    1) Posed in DAZ Studio exported as .obj

    2) Imported to Blender, it's considered a bunch of pieces, which I joined,

    3) Using 3D-Print tools (part of Blender, but you have to turn them on first) Clean up > Make Manifold and export as .stl

    4) Bring into Chitubox (slicer that comes with a lot of resin printers) and scale against another figure. Add supports and print.

    The second figure I had to add weight to the cloak (Solidify) because it was one plane thick.

    I used Meshlab when I had a filament printer. I quite liked it.

    My resin printer came with an absolutely awful slicer and I got Chitubox and think very highly of it.

    thank you for the steps!smiley

    the first thing they want me to make is custom keyboard caps for a 104 keyboard
    they want to block some keys from being pressed
    its the back of the key is tricky cuz it has to secure on to the peg.  its a very precise measureent

     

    i'd like to print some shrubbery for my christmas village.

    and a miniature of an aviation headset with mic boom to make cute carm bracelet charms. my dayjob does air to ground communications.

     

    what does g mean in g coordinates?

  • kenshaw011267kenshaw011267 Posts: 3,805

    This is straying pretty far from DS but here goes.

    If you can 3d model then you should be able to make the custom keycaps pretty easily. You can easily enough find keycap STL files, and lots of other stuff, at thingiverse as well. But you'd need to add the stop yourself.

    I hope you're going to be doing it to a more regular keyboard and not that Model M.

    Shrubbery is easy. Find a model you like, from your Daz assets, thingiverse or one you model yourself (keep in mind that the mini will be small so don't go crazy on detail). Same with the headset. Once you have either an OBJ or STL file feed it into your slicer and put the resulting g-code file into your printer. The printer will have either an ethernet connection or an sd card reader expressly for that. From what I could find it appears to have bopth, or possibly wifi it wasn't 100% clear. Every printer I've ever seen has an sd card reader so that is how I do things as it lets me put the printer out in the garage rather than somewhere the fumes will be an issue.

    I assume g coordinates is actually g-code coordinates. g-code is a family of related programming languages used in CNC devices, including 3d printers. What the g stands for I have no idea and a few minutes on Google didn't turn anything up. The coordinates are in 1 mm increments.

  • I hope you're going to be doing it to a more regular keyboard and not that Model M.

    That's a Unicomp. I have two Model M's that are still working perfectly, with USB adapters, after almost 35 years. My Unicomp was half the weigth and while I was briefly in buckling spring heaven on every computer I use, it crapped out after two months, as did the replacement. I hear they recently abandoned the replaceable keycaps as well. Incredible how badly Unicomp could misunderstand their customers: People who would search and search and spend $400 bucks on a relic because of the quality are not interested in you shaving pennies off the price and delivering cheap garbage for $94.

    Sorry for the rant, but I've never been so first excited and then dissappointed in a company and product.

    the replaceable key caps is a big issue at day job.  the operators are used to the exrra wide key.  the 104 they buying now is 2 indiviual keys. makes the operators upset.

    they recycling the old keycaps from the rs6000 days 20 years.

    I'm a kb snop too. I've had better luck with unicomp, I did buy from them right when they started. I have heard quality has dropped off. 

    I just used Model M as the generic term.

    I've had really no luck exporting models out of DS straight into my slicer. There are always printing problems. It is obvious to me that there needs to be an intermediate step to do something. I'm not sure what.

    It would be so cool to be ale to print your creations in DS.

    What settings are you using in the slicer? Are you adding supports?

    yes..supports, its mainly turns to stringing, holes, etc. The print has holes it what I mean. 

  • richardandtracyrichardandtracy Posts: 5,922

    Is there any chance you could describe the process you go through, step by step.

    First off, I assume you export .obj, and opening in the slicer.

    Does the figure have clothing? If it does, that can be a source of problems. Most DS clothing is surfaces with no thickness, which does not print well, giving holes or disconnected areas. Exactly how it manifests itself will depend on whether the printer is a wire or resin type and the slicer response to thin surfaces. I have started to write a program to deal with that, but have only tested it once on my printer (an Anycubic Photon) before my allergy to the resin stopped my using it stone dead, and my interest in verifying the program waned a bit.

    Have you tried converting to .STL as an intermediate step? If not, and you don't have one, I wrote a Windows program for myself to do that and it's a freebie here: http://www.chestnutpens.co.uk/misc/objtostl.html. Put the .STL through the slicer, may give a more complete model. Obj files straight into slicers is moderately new and yours may not be bug free. Then if it still goes wrong, could you post a photo? Someone may recognise the problems and help or at least come up with plausible options to try. If not.. it'll make the rest of us feel better because we're not the worst off.

    Stringing can be caused by a number of factors. Did you level the printer? You need to put the printer on as level a surface as possible and then do the leveling process for the printer.

    But holes means the geometry isn't right. If you read back over the thread someone details how they take their DS OBJ into blender and close up the holes in the geometry.

    Sorry for hijacking the topic a little but, last off topic post.

    I love buckling springs so much that I was going to buy a third one and hope for the best. When I returned to the site, I found something called the "New Model M", supposedly with better QC and keycaps. After reading some positive reviews, I of course couldn't resist. I'll let you know how it works out.

    Oh well. My "New Model M" just arrived. True, it seems sturdier, the switches are a dream, but it no longer has detachable keycaps and the Scroll Lock LED doesn't illuminate. Of the three keyboards that I've bought from them, two stopped working within three months, and the third was deffective on arrival. We'll see how long this one lasts.

    Well crap. Mine is pretty clearly on its last legs. I have a Corsair with Cherry blues at work I like well enough but it will be sad day when buckling springs go away.

    The mouth is a likely source of holes, the cheeks are too thin to print, at least that's my experiance. On the prints i have done so far I remove the eyelashes and then used UVmapper to delete the materials of the mouth and teeth ( that deletes the mesh for those parts ) then I put the model through Meshmixer and seal all the holes. I haven't found a way to print hair, I think it needs to be a solid hair shaped blob to print hair.. Ears and fingers can also be a problem if the scale of the print puts them below the printer resolution.

    ...looking for a boeing b17 model to print on it.

    I picked up one (B-17) in the Daz store that was sort of ok. The trick seems to be to search for WARPLANE instead of keywords like aeroplane and aircraft.

    The discussion about the resins and the fumes and ventilation kind of reminds me of PVC clays like Fimo and Sculpey. You bake those in an oven and they shrink a tiny bit, and become fairly durable.

    So I assume that when the resin has cured or has otherwise settled down, the smell or any off-gassing dies down as well? And hopefully the printed surface will take a good quality, durable paint like Testors or Humbrol, Polly S etc. Or do you need a cleaning agent like Polly S Prep say.

    P.S. Glancing at the Wikipedia English entry for Fimo mentions "issues"... ergo the article says "you can slice it after it hardens"... I'm thinking that may be possible but you'd need an X-Acto saw or a Dremel tool, and I wouldn't want to breathe in the dust!!  However the Wikipedia item reminded me that soft PVC clay will indeed slice *VERY* thin with an Olfa or Stanley knife, possibly thin enough to make Geoshell-like, physical layers of durable color that could be glued to various surfaces of 3D printed, resin objects. On the down side I think thin slices of Fimo are hard to bake. But you could add nicely sculpted items of clothing, made out of Fimo, to a 3D "printed base" action figure. Like a gown or a leather jerkin or a belt and buckle around the waist that is really "3D".

    I wonder if these printers will do a negative printout? Then you'd have a nifty mould and with some tweaking, a reproducible action figure - press bits of Fimo (in appropriate colors) into the mould and then bake the pieces of clay and assemble the figure. Just saying.

    And if you could 3D print in beeswax or paraffin or a similar substance then bingo - here we go with lost wax castings!

    Attached, a sample object made out of Fimo and varnished with clear and white acrylics. Point being that a fine artist's brush can supply surface detailing that the 3D printed resin can't quite match.

  • With my Anycubic Photon DLP printer on a 90mm high figure I was able to see the fingernails and the ties on the hips of the bikini bottoms. DLP printers, at least, can do incredibly fine models. On the one photographed, there was a bit of delamination in the base, which is why I added the filler. The head height is approx 12mm (1/2") to give a sense of scale.
