  • Printing for Printing’s sake

    I have spent a good portion of the last two weeks just getting my Bambu P1S setup to where I want it to be. I believe I’m closing in on a good setup.

    I thought you were printing in 15 minutes?

    I was! Out of the box, the P1S is great, and lets me start printing without a ton of calibration and tinkering. As I continue to print, however, I wanted some additional features that needed some new parts.

    External Spool

    By default, the P1S has an external spool mount on the rear of the device. This allows the spool a nice path to feed the printer. However, if you have an AMS (which I do), you need to hook up the tube from the filament buffer to the printer.

    There are several versions of a Y connector which allows for multiple paths into the printer. I chose the Smoothy on a recommendation from Justin. There is a mount available that lets you attach the Smoothy to an existing screw hole in the P1S, or use magnets.

    Since I have the P1S close to a wall, I wanted to relocate the external spool to the side of the machine. This gives me easier access to spool and allows the printer to sit closer to the wall. For that, I printed this external spool support.

    For assembly, I couldn’t print everything. I needed some M3 screws and a set of fittings. For the Smoothy and the external mount, I used all four of the 10mm fittings (three for the Smoothy, one for the external mount. However, everything went together pretty easily, and my setup now allows me to print from either the AMS or an external spool.

    Raise it up!

    Bambu recommends printing with the top vented for PLA. That is difficult to do when the AMS is sitting on top of it. Thankfully, there are a LOT of available risers, with many different features. After a good deal of searching, I found one that I like.

    Why that one? A few of the more popular risers are heavy (like, almost 3kg of filament heavy). And yes, they have drawers and places for storage, but ultimately, I just wanted a riser that held the glass top higher (so it could vent) and had a rim for the LED strip I purchased to illuminate the build plate better. My choice fits those requirements and comes in at under 500 grams.

    Final Product

    With all the prints completed, I am very happy with the results.

    Here’s everything I used for the setup:

  • A new To(y)ol

    I have wanted to pick up a Bambu Labs P1S for a while now. I saved up enough to finally pull the trigger, and after a few days of use, I could not be more pleased with my decision.

    Why Bambu?

    There are literally dozens of 3D printers out there, and choosing can be difficult. I certainly spent a great deal of time mulling over the various options. But, as with most things, the best advice was from people who use them. Luckily, I have not one, but two resources at my disposal.

    An old colleague of mine, Justin, is usually the first to such things. I typically joke that I usually do the same things that Justin does, I am just usually lagging behind in both time and scale. IE, Justin does it bigger and better. He and I chat frequently, and his input was invaluable. With regard to 3D printers, the one comment he made still resonates:

    I want to design stuff and print it, not tinker endlessly with the printer itself.

    Justin had an Ender (I do not recall the model) for a bit, but never really messed with it too much. After he picked up a P1P, the design and printing started to flow. He had nothing but good things to say about most things Bambu, save, perhaps, the community… We’ll get to that in a minute.

    Additionally, I discussed different printers with the proprietor of Pittsburgh3DPrints.com. He has a number of different brands, and services them all, and he recommended the Bambu as a great first printer, for many of the same reasons. What reasons?

    1. Ease of Use – From “cut box” to print was honestly 15 minutes. The P1S is extremely user-friendly in terms of getting to printing.
    2. Feature Packed – Sure, the price tag for the full P1S combo is a little higher than most printers. But you get, out of box, the ability to print most filaments, including PLA/PETG/ABS/ASA, as well as 4 color multi-color prints.
    3. Expandable – Additional AMS units get you up to 16 color prints.
    4. Ecosystem – Bambu has been really trying to get makerworld.com going, and they have had some success. The makerworld tie-in to Bambu Studio makes printing other’s designs quick and easy.

    First Impressions

    As I mentioned above, unboxing was easy with the included Quick Setup guide and their unboxing video. The first thing I printed was the included model for the scraper handle and holder. I do not recall the exact print time, but it was under an hour, and I had my first print!

    The next two prints were some fidget toys for my kids. I can tell you these took 48 minutes each, as both kids were anxiously waiting every single one of those minutes. One feature the P1S has is the ability to capture time lapse videos for your prints. Here is the one for one of the fidget rings.

    Now, I do laugh, because the running joke with those who own a 3D printer is that you spend most of your time printing stuff for the printer, which is highly meta and also seems like a gimmick to buy more filament. The P1S ejects waste out of the back into, well, thin air. Many folks have designed various waste collection solutions, most affectionately knows as “poop chutes.” I found one that I liked and set about slicing it for printing.

    Oops…

    This is where I ran into a little issue. I tried to start one of the prints (for the bucket) from the Bambu app. Instead of slicing on my PC and sending to the printer, I used the profile published. That, well, failed. For whatever reason, the bed temperature setting was set to 35°C, instead of the 55°C that the Bambu Studio slicer sets.

    I’m not sure if the profile had a cool bed setting or what, but that through off adhesion of the print to the bed, and I ended up with a large mess. I re-started the print from the Bambu Studio, and had no problems. Printing the three pieces of the chute took about 9 hours, which represents my longest print to date.

    Next up?

    I have a few things on my list to print. Most center around some organizational aspects of my office, and looking to use the Gridfinity system to make things neat. My wife asked for a few bases for some signage that she uses for work. This requires some design on my part, so it is a nice challenge for me.

    Both my son and one of our neighbors have expressed some interest in design and printing, so I look forward to passing on some of what I’ve learned to new designers looking to bring their designs to reality.
