Micron/Micron+ Kit Information Roundup (Mid 2024)


Well-known member
So I've been thinking about building a Micron - the smaller PrintersForAnts re-imagination of the Voron V2.4 that uses 1515 extrusions. Specifically, the 180mm Micron+.

If you read any of the (unfortunately few) Micron build threads here or on other forums, or watch any of the YouTube reviews, a few things stick out:
  1. Everyone has used different kits
  2. Kits vary wildly in terms of what is included
  3. Kits (like the Micron itself) are evolving over time
  4. No vendor or manufacturer stands out (yet) for having the best kits, nor is there a dominant consensus in key areas about certain parts.

So with that in mind, "doing research" before making a purchase is difficult. Since I had already put in the leg work, I decided to capture what I've found in a spreadsheet, in case it helps others.
If you have any other insight, questions, comments, etc, about Micron (or Micron+) kits, please feel free to join in here!

(Spreadsheet will be in the second post)

//edit: As a v2.4 owner, I also have to link this hilarious Micron serial request. 😁

Now, for a few examples of what makes things tricky:

First off, the heated bed. LDO is normally toward the top of the market for the products they produce - such as the edge-to-edge silicone heaters for the V2.4 series, or the fast-heating edge-to-edge Polyamide heaters for the V0 series. But for the Micron, they have... this? An undersized heater that doesn't go anywhere close to the edges. 😑

source: https://www.teamfdm.com/forums/topic/2121-micron-180-ldo-kit-build/

Likewise, we have a plethora of bed shapes. One of the neatest aspects of the 180mm Micron+ is its ability to use the ubiquitous (and high quality) Prusa Mini build plates. hartk provisioned for this years ago, giving two bed shapes, one a simple square, and one which has the Prusa-style peg mounts:

However, not all manufacturers have used this build plate shape. LDO did, for example (as seen in the photo above), as did Mandala Rose Works below:
source: https://mandalaroseworks.com/products/micron-185-magbed

Blurolls seems to have adopted the bed profile (good)... but for the kits, at least as far as the assembled printer photos show, they matched the sheet shape to it (bad). So this is either installed with the sheet tab holes over the pegs (which would make insertion/removal difficult), or it gets installed backwards and loses the alignment benefit. They seem to have adopted the full Prusa shape for their plates in the separate bed/heater/sheet bundle though, so hopefully this course correction sticks. (Also note the edge-to-edge heater Blurolls uses, in contrast to LDO's offering above.)

Separate Version:

Fabreeko matched the bed profile (good), but only copied half of Prusa's sheet shape (omitting the front grabbing tabs), then mounted the sheet 180-degrees rotated so it loses the self-aligning aspects of the rear posts. 😑 Which is particularly frustrating, as the Micron promo render, with the correct plate shape, is also right there next to it on their product page.

West3D with their "Exclusive West3D Design" did something completely different from either of hartk's drawings:
source: https://west3d.com/products/printer...lus-180-salad-fork-180?variant=44350541201620

DLLPDF seems to be one of the few offering a *160mm* build plate which matches neither of hartk's drawings. (Mandala Rose Works also offers this size.) Of the Micron kits, it seems as though 98% of them are the 180mm Micron+... with very little buzz about the Micron 120 (the original/official size) or the 160 (which might only exist in comments because of Salad Fork parts?).
source: https://dllpdf.com/micron-build-plate-160mm

Which leads us to the last contender.
Formbot seems to be the only one who understood the end goal here and got *both* parts right: 👍
source: https://www.formbot3d.com/products/...uality-corexy-3d-printer-kit?VariantsId=11069

Thankfully, while many have missed the mark on the build plates, and some on the heaters, most seem to have adopted the Prusa-style build plate shape... so the rest can be corrected by swapping plates. Notably, the vast majority of the "aliexpress" offerings are of the Prusa-style shape, as are the known players like LDO, Mandala, etc, so that option seems to have the clear majority momentum (a good thing IMHO). It really seems like West3D is the outlier, which is an interesting "miss" for them.

//Edit: It looks like Funssor also is close. They have a bed with embedded magnets (very much like the Mandala Rose Works offering), in the Prusa Mini shape, with a Prusa Mini-shaped build plate. But somehow they assembled the two backwards for their listing photos. 🤷‍♂️ 😁

Impressive amount of information Dave!

Thanks! Trust me when I say, that I really hadn't intended (or expected) to do that much work. 😁

Selecting a V2.4 kit at this point in time is relatively painless - the are all fairly mature, and pretty much on par in terms of completeness - you are just making secondary decisions on component quality, hotend choices, etc. So I was a bit surprised at how fragmented things were for the Micron. Obviously the Micron is newer, more of a niche/specialty machine, etc, and that was clear and understood from the start. But a lot of big players are involved, and I think I had believed that that (and their prior experience with V2.4 kits) would have brought them all up to a different starting level.

As it stands, Vivedino/Formbot has the only real "complete" standardized Micron+ kit, and West3D, close behind them, is basically custom kitting bespoke machines from scratch - I can't imagine the complexity on their end for building harnesses with so many customer-selected variations. LDO seems like they are inching towards a kit, having already knocked out some of the more custom parts (heated bed, panels, motor kits, etc). Maybe something is in development, or maybe not... but they don't have an offering at this time, it is only others who have grouped their parts together. Fabreeko is just missing half of the machine... And Blurolls curiously has quite complete kits but doesn't offer them with their own CNC parts - something that so far is unique to them. (Edit - see below, I had missed the Funssor kits.)

It's all just... interesting. Maybe I caught them at the wrong time, and things will be different in a few months? 🤷‍♂️

So then the other thing I was going to status - CNC parts. Because anyone can print parts, but you know something has a market when a vendor commits it to metal. 😁

Blurolls has a fairly complete offering here. Their kit ($145 with free shipping) includes:

These parts have a bit of a "hefty" look to them - as if they took the printed part models and simply machined them as-is, rather than optimizing for the material change.

They also have a Mini Stealthburner carriage for $19.90 with free shipping.

Fabreeko / HoneyBadger makes a flashy looking CNC toolhead carriage for $34.99 (plus shipping?)

Funssor has a CNC X-beam for $29.99 free shipping:

... and a redesigned (plate-style) rear-tensioned motor mount / X-Y set for $99.99 free shipping.
(So clearly some thought and effort has been put into these.)

... and adjustable Z idlers for $42.85 free shipping

... and Z joints for $29.90 free shipping

... and X carriages for Mini Afterburner or LGX Lite ($31.50/each with free shipping)
source: https://www.aliexpress.us/item/3256804514487463.html

So that's actually quite a showing for CNC aluminum parts! 👍 No CNC Boop yet that I'm aware of... which is interesting, as I feel like TAP is one of the more popular CNC parts for other Voron models.
Two other things I can mention:
1) AliExpress seems to handle "Micron" and "Micron+" differently in search results. The majority of kits and parts are marketed for the Micron+, and some vendors just flood their listings with words (having both Micron and Micron+ in the listing), so generally either works. But if looking for parts, try searching both ways.
2) I missed the Funssor kit in the spreadsheet, so I will add that in a little bit. (Edit: Done.)
