Building a Bento Box

I got a P1S for my family as an early Christmas present. I’m interested in creating parts that may eventually be used in cars, so I’m trying to get things ready for full-time ABS and ASA production.

This is my 4th print using ABS. First time was an okay benchy which needed some flow calibration and displayed some slight bowing at the base. Second time was a good benchy which seemed dialed in. Third print was an articulated Onyx Pokemon which seemed great.

I’ve printed the main body for the bento box in 3DF transparent black ABS.

Some of my tweaked settings for success were:

  • Blanket over the printer. This is in my garage and temperatures dip. The blanket helped with the warping.
  • Setting the bed temp to 100C and setting the level to around 40mm down from the top with the chamber fan at 30%. Did this for around 15 minutes to get everything inside up to temperature.
  • Nozzle temp first layer of 260C
  • Nozzle temp other layers of 270C
  • Bed temp constant 100C

I plan on printing the other components and sourcing the parts spread out across December, so I’ll post updates!

IMALlama,

100 bed is pretty reasonable. 260/270 seems pretty toasty, but if it works it works.

Do you have a bedslinger, CoreXY, or something else? Bedfans made a world of difference for chamber heating rate. There are a number of bedfan and active carbon combinations that I’ve found to be fairly effective at chamber heating and reducing odors.

Are you recently enclosed? If yes, beware that everything will expand enough to throw off your first layer if you don’t accommodate for it.

I’ve only run ASA so far, but even sticking with the same brand I’ve noticed that different colors have very different temperature and extrusion multiplier needs. Prior to ASA I stuck with PETG and I used the same settings for any color but white.

Car,

I have an enclosed CoreXY printer. There’s a lot of variety in filament affordability, so I’m working my way through the (cheap) stuff on Amazon, slowly but surely. The 3DF branded ABS used here looks nice but was wound like hot trash. I ordered three rolls and I think I need to return two of them.

Any particular brands you’ve run that have been consistently good? I’m eventually going to try the good stuff like Polymaker, but I can get two rolls of play material for the price of one nice roll.

IMALlama,

I’m currently running polymaker ASA. It’s not cheap, but it’s not that out of the ordinary price wise for ASA. I am somewhat tempted to give Atomic Filament’s ABS a go since they were one of my go to PETG companies and their filament was super consistent. Polymaker’s ASA has been fairly solid other than the fairly different printing needs of different colors, which is something I haven’t experienced on other types of filament before. Maybe that’s normal for ASA though.

I’m running a bedfan/filter combo called “the filter”. It’s drastically reduced chamber heating times for me. No idea if theres a version out there for your printer, but there might be given it’s popularity and similarities with the Voron trident.

yokonzo,

This is cool but be weary abs isn’t necessarily food safe, you can get food grade filament though

Beyond filament, the materials used in most 3D printers aren’t food safe either. PTFE tubing to guide the filament, brass nozzles and gears.

Also, the biggest issue are the micro cavities between the layers that can host germs even if you wash it.

sugar_in_your_tea,

Yup, I’d only trust this as shelf art.

jjagaimo,

FDM printed plastics aren’t food safe because melting the plastic and creating layers makes it porous and a breeding ground for bacteria. Brass nozzles also contain lead albeit in trace amounts.

Car,

I really should have mentioned that this isn’t a conventional bento box. It’s a DIY filer unit to cut down on some of the ABS and ASA nasties that come with printing.
