January 18, 20223 yr 1. What do you have 2. What's the favorite thing you've made 3. What's the most common type of things you make 4. If you were to buy from scratch right now, what would you get? I've been perusing the stuff off and on for a while, but it still seems too nascent and niche to have a consumer printer that's solid and foolproof, i.e. the Brother Laser Printer of plastics. Is that about right? Or is there really reliable stuff now?
January 20, 20223 yr I have a Crealty Ender 5 with a few modifications (bed support, new quiet control board, glass bed). For the price, I'm a big fan. Now that I've got it dialed in, it prints quite well - everything from random enclosures, to parts for an espresso machine, to Nintendo Switch controller holders, to those little wrenches you use to remove bike tires, etc... That being said, no consumer 3d printer is going to be foolproof. There is a lot of trial and error whether that's playing around with bed temp, extruder temp, filament type, the actual design, fill rate, support structures, etc.... I've made a bunch of things with mine that I'm quite happy with. Probably the biggest achievement was using my 3d printer to build the parts that go into my Lowrider CNC machine. It's a fun hobby. But you have to treat it as a hobby, not as a tool or office equipment. You will have prints that epically fail and you just have to edit and try again. If that doesn't sound fun, then save yourself the $300-$500 or whatever it is they go for these days. But when it all works as planned, it's pretty fucking cool.
April 2, 20223 yr I should really be all over this. A variant was invented at UT while I was there. I have written patents on it. I'm a geek and a long time ago, I really enjoyed mechanical drawing (art for the artless, like me). But, like a lot of technological things (raspberry pis, linux computers, etc.), I doubt I would end up making much use of it once the novelty wore off. Maybe it goes back to why I didn't pursue an engineering career, per se. I just don't have much creative inspiration.
March 22, 20232 yr Bump. I just ordered a Bambu X1C and I'm super excited to get my hands on it! I did a bunch of 3D modeling while I was an engineering student so im hoping I can remember some of the solidworks tricks I used to know lol
March 22, 20232 yr Get some shit filament to learn on and then get the good stuff once you feel comfortable. Good filament makes a big difference.
April 8, 20232 yr Bump. Got my Bambu X1C and it fucking RULES! I had a nearly perfect benchie 45 minutes after unboxing and setting it all up. Crazy fast self-calibration and bed autoleveling Looking forward to making random shit and doodads, definitely gotta print a lightsaber for my nephew!
April 11, 20232 yr Yeah this thing fuckin RULES! I tried swinging for the fences and set up a 16hr print for this pretty big dice tower just to see how it'd do, and maybe get a fun thing to bring to D&D video_2023-04-10_00-33-40.mp4 Really really easy to use and get excellent results with.

April 11, 20232 yr So the dominant mode of layering these days is to melt a polymer filament using a three-axis print head? And that seems to produce a reasonable material? That's so much remarkably simpler than some of the early methods. One of the crazier, but actually legit ones used a photopolymer masked with paper, lasers and/or knives operated on three axes trimmed away the paper mask and began to solidify the polymer, which was then hardened using UV light. And then there's UT's own Carl Deckard's, that used lasers on three axes to melt a pile of polymer particles into shapes.
April 11, 20232 yr FDM is the filament melt like in the video above, and there's also very accessible SLA printing where you have a reservoir of UV-sensitive resin that you use a photomask to cure and it magically draws your item out of the liquid resin. You can get significantly better surface finishes with resin prints, to the point of them being indistinguishable from injection molded pieces. So instead of the paper and photopolymer mask as you're describing, it just uses a Texas Instruments DLP chip to project ultra-accurate light into the resin to cure it. But your choices of material are limited and you have to deal with all the sticky and VOC-filled resins, along with much more post-processing from washing and curing the pieces after printing is complete. I'm very fortunate to have taken engineering drafting (as a mothafuckin study abroad in Austria!) with Dr. Wood at UT while I was still an engineering student - he was on some of the original patents for 3D printers and this thing that got shipped to my door would make his head explode lol The print process is pretty straight forward: either make your own 3D model or just download one from thingiverse/thangs/whatever, drop it into your slicer program to generate any necessary supports and gcode for the print head pathing, and then send that gcode to your printer and hopefully you don't get hot spaghetti Edited April 11, 20232 yr by Captainant

I have forgotten the names of the players, but the photopolymer thing came out of a company from Israel that originally tried to trademark "sterelithography," and this sounds like its descendant. One I worked on used electrodeposition of nickel on charged surfaces. Actually seemed pretty plausible, but never went anywhere. Billy Wood? Drafting at UT in the 80s was super chickenshit, just some three-view and dimensioning stuff in workbooks using graph paper. The only CAD systems were CADAM on a S/360 and it was horrible. I took two years of pencil/pen "mechanical drawing" in high school because I liked it so much and learned AutoCAD in the summers at TI.

April 18, 20232 yr A few more days of tinkering and I'm starting to figure out some cool tricks to help with support removal. Turns out, PETG and PLA have very poor layer adhesion thanks to chemical properties, so I can use the AMS to switch between the material for where the support touches the model. The end result is a very dimensionally stable model that's not too terrible to remove the supports from. The downside is it goes through a shitload of filament just purging one material to print the next. The model took 12grams of material, but the print used about 35g in total including all the purge cycles.

April 27, 20232 yr Minor bump update to my 3D printing journey: I've settled on using PETG primarily since it doesn't put out any VOCs when printing, and my printer is in my office so that's that lol. Only challenge is that PETG is a much fussier material than PLA to get clean results with, and most of my prints have some blobbing and minor stringing. I did some googling, and apparently I need to turn off the "slow down for overhangs" setting in my slicer and that'll fix it? Hope it'll work! Ive been trying to print Prusa's new rocket engine model and the print fails when it gets to the fine details on thin connections edit: that did it, plus some cooling fan tuning! video_2023-04-27_12-09-10.mp4 Edited April 27, 20232 yr by Captainant

I only ask because chemically modifying plastics to allow them to adhere to dissimilar plastics is pretty much what I do for a living. Honestly, the simplicity and consistency of a filament is what makes is most useful in printing. I've messed with a PETG that had a speckled appearance and I've had a ton of challenges getting consistent results with it, but the plain single color filament print beautifully and predictably. Plus, its neat to exploit some different chemical properties to get better dimensional results - you can get perfectly supported overhangs with zero surface marring on the bottom side at the cost of 10 or so grams of wasted material. But if you print many more of the same item with the same filament swaps at the same layers, you reduce the overall amount of waste since it spreads it across more items. That said - any good consumer superglue recommendations for making PETG stuff stick to PLA and $(othermaterial)?
July 14, 20232 yr I deal with stuff at a raw materials level more so than a consumer level. Mostly it's stuff like making a PE resin with specific properties in order to allow it to adhere to dissimilar resins (like PP or something else) at a molecular level. So like if you wanted to blow a film with a layer that has heat shrink properties and a layer that has UV resistance or an O2 barrier or something, you could either throw a layer of what I make in between or mix some of it in with one of your base resins depending on the application and your final product wouldn't have layers that want to separate. But I'm usually told to make something particular and not always filled in on the end application of whatever it is I'm doing.

September 20, 20232 yr Bump - working on printing up a big board game project called Hextraction. Lotta print time to get through.... Also, Bambu just announced a new entry level printer that gives you a 180 mm^3 build volume and an AMS unit for $450!

The item is about 6.75 inches by 2.75 inches by 1.5 inches overall and is about 1/8-5/32 inches thick. It is molded from hard black plastic with some flexibility. It has shrunken over time and cracked around its 2 mounting screw holes. The item is not subjected to flexing when mounted and in use, but it is subjected to engine and road vibration. The item is not subjected to any engine or other high temperatures, but is subjected to our high summertime air temperatures in its mounting position 1 foot above black asphalt roads. Only the outer surface shown in the 4th/last photo is visible when mounted. If this is something you would take on (for cash) please let me know.

March 25, 20241 yr In terms of prints, I've made a few functional prints to replace broken bits and greeblies around the house, recently printed and painted a mini from HeroForge (the .2mm nozzle is pretty pretty good) for a D&D game I'm in, and just started printing some stuff in 95A TPU. My sister (no pics) was in town for me and my wife's baby shower last weekend and I'm sending her home with a couple of mini airless basketballs printed in TPU.

I'm super excited to have my printer handy for all the little bits and bobs that you find yourself needing when you're expecting a little one in the house.

Looking at the R Qidi X-Plus 3 for the size of the bed and it's capabilities, but I'm open to suggestions. $600 to be able to print CF nylon with a heated chamber is pretty hard to beat. One thing to consider is that Nylon, ABS, and a few other materials off gas VOC's when heated for printing, so be sure to have excellent ventilation or not set it up where people tend to be. I found a pretty thorough review of that printer, and it looks like it'll be a solid prototyping machine. https://www.3dsourced.com/3d-printer-reviews/qidi-tech-x-plus-3-review/ Do you have much experience with FDM 3D printing?

I think I learned Solidworks at my engineering side job, which worked with NASTRAN finite element modeling software. 3D was just coming into vogue and I remember struggling to draw with it. Mine was Charles Perkins. Wood was head of engineering graphics back then, which assumed a larger role as CAD came into play. In our pre-project class, we had to use NASTRAN on a VAX and you had to enter the material data in a "comma matrix" form for each element of the structure. It was horribad just from a data entry/error standpoint. You'd submit your model to the processor in a batch-processing mode and then watch it complete or error out. Lotsa "fuuuuuuucks" and "yessss" while watching that.
