  1. /3DPG/ Pastebin v2 - Last updated 30-12-2018
  2.  
  3. >General info
  4. 3D-printing is the common name for what is technically called additive manufacturing. Traditionally, manufacturing methods used to be subtractive: you start with some material, take a lathe/mill/hammer and chisel/whatever and remove all material that is not the end product. Additive manufacturing start out with nothing and adds material in just the right places to form an end product.
  5.  
  6. The most common forms of 3D-printing for hobbyists right now are FDM (Fused Deposition Modeling) and SLA (Stereolithography), with FDM being the most common and most discussed type in /3DPG/: most of the information in this pastebin applies to FDM. FDM boils down to taking filament (basically plastic wire in a standardised thickness) and shoving it through a heated nozzle. That nozzle is then moved in three dimensions (hence the name 3D-printing) to extrude material and form the end product.
  7.  
  8. Workflow for 3D-printing is as follows:
  9. >Obtain a 3D-printer, assembly if necessary
  10. >Obtain filament
  11. >Design a product using CAD
  12. >Turn CAD file into machine code using slicing software
  13. >Start printing
  14. >Fail
  15. >Troubleshoot
  16. >Repeat last few steps untill succesful

  23. >Buyers guide
  24. The best value printer to buy right now is the Creality Ender 3. Under 200 USD, bolts together easily and has print quality on par with more expensive printers. If you want a bit more print volume the Creality CR-10 is also a good pick.
  25. The old golden standard used to be the Prusa i3. It had great value when it was first released, but the market has moved at an extreme pace: the Ender 3 gives you most of the print quality at a fraction of the price.
  26. Are you a professional and do you want a printer that just works out of the box for a few thousand more? Buy an Ultimaker.
  27.  
  28. Note that all printers, especially the good ones, get cloned by the Chinese in an instant: Banggood, Alibaba, etc. all offer cheap imitations (AKA chinkshit). This can be a bad thing (as can be anything on those sites), but that's not always the case. Some Chinese companies have evolved from making simple copies to genuinely improving them and pushing the market further: Creality can be considered an example of this.

  32. >Filament
  33. This stuff is the food of your 3D-printer: feed it garbage, and it will shit on your carpet. Simply put, a spool fo filament is just a spool with plastic wire on it. Sounds simple right? The main problem manufacturing this stuff is controlling chemical composition and ensuring a consistent diameter of the filament, which is not as easy as it sounds. Buy namebrand stuff if you're starting out, only with some experience should you move on to the cheap, possibly unreliable stuff. Remember, there's nothing more expensive than a failed print.
  34. Filament comes in different thickness (usually 1.75 and 2.85mm) and materials. The most common materials right now are PLA, ABS and PET. PLA is really easy to print with and should be your starting material. ABS is stronger but much harder to print, which explains the popularity of PET: it has most of the strength of ABS without the printing difficulties. Beyond these there's about a dozen reasonably common materials, each with their own material properties, printing temperatures, speeds and difficulty level.

  38. >Troubleshooting
  39. Troubleshooting what went wrong on that list print is an art to be mastered. Simplify3D has a great guide on their website, if that fails, use the other two below. If that doesn't work, post your failure in the thread, we can then have a laugh at you and possibly come up with a solution.

  45. >Where to get 3d models?
  46. There are huge online communities where people share 3D files to be printed, some of them are mentioned below:

  48. https://www.grabcad.com/

  55. >Making 3D models yourself
  56. 3D-printing requires CAD-software (Computer Aided Design) and a design (duh). Optimising your design for 3D-printing can make a huge difference in both print time and failure rate:
  57. http://support.3dverkstan.se/article/38-designing-for-3d-printing
  58.  
  59. As for CAD-software, you can use a plethora of programs: Solidworks, AutoCAD, Fusion360, doesn't really matter. Fusion360 is free for hobbyist users and relatively easy to learn, so I'd recommend that unless you have particular requirements.

  65.  
  66. >Slicers
  67. Once you've made a design in CAD, you can then export it as .stl (Standard Triangle Language) or .3MF (3D-manufacturing format).
  68. These files types can then be used by a slicer program, which then slices (hence the name) it into layers for your machine to print.
  69. These layers can then be exported to your machine in .3MF or .gcode (machine code) format, through an SD-card or cable connection.
  70.  
  71. The three biggest slicing programs right now are Cura, Slic3r and Simplify3D, each has it's pros and cons.
  72. Cura is free, will suit most amateurs just fine with an easy interface, and yet has enough depth to it for expert-level users.
  73. Simplify costs money (but is easy to pirate) and has slightly more expansive options than Cura does.
  74. Final choice would be Slic3r, the OG open source slicer - the perfect choice if you're a /g/entoomen running some wierd Linux distro.

  83. >Hotend
  84. E3D and their V6 hotend are the industry standard right now if you want to build your own printer.
  85. Micro-Swiss offers a lot of ready-to-go kits to upgrade existing printers, might want to check those out.
  86. If you need high temperatures (>300C), consider a Prometheus V2 or B3 Pico. For sheer print speed, the E3D Volcano is hard to beat.
  87.  
  88. >Extruder
  89. Bondtech/BMG extruders are probably the best in the market right now - but also the most expensive.
  90. A good alternative would be the E3D Titan - a compelling package when combined with the E3D V6 hotend.
  91. You could also stick it to the man and print your own: https://www.thingiverse.com/thing:2289203

  117. >What printer should I buy? [Last updated 30-12-2018]
  118. Under 200 USD: Creality Ender 3
  119. Under 500 USD: Creality CR-10
  120. Under 1000 USD: Prusa i3 (Mk2 or Mk3)
  121. Under 1500 USD: Lulzbot Mini
  122. Buyer beware: some chinkshit clones are garbage. Some can be genuinely good, though.

  129. Blender, Solidworks, AutoCAD etc. all works, but Fusion360 is free:
