Opening:
This was a good week for remembering what 3D printing is actually useful for.
Prusa put eight-tool INDX on its larger CORE One L+, adidas showed that fully printed footwear is becoming a real consumer product, and Thingiverse’s biggest model winners were replacement parts for broken household gear.
Less benchmark chasing. More useful stuff.
The 60‑Second Extrusion:
Prusa opened CORE One L+ INDX orders. You can now buy the large enclosed machine with eight tools or convert an existing L+.

Prusa puts eight-tool INDX on the CORE One L+
What happened
Prusa quietly made the CORE One L+ with INDX real this week.
As of August 27, you can order a complete machine or an INDX conversion kit for an existing CORE One L+. The system supports eight independently loaded tools, and initial shipments are currently expected to begin November 5.
Why it matters
This makes Prusa’s own lineup much more interesting.
The XL still has a larger build plate and swaps entire toolheads. The L+ gives you an enclosed chamber and eight loaded INDX tools in a more traditional CoreXY layout.
For some buyers, that is going to be a much better fit.
Who should care
Prusa power users, soluble-support users, engineering-material makers, print farms, and anyone about to spend XL money.
Extruder Report verdict
This might be the most interesting version of INDX.
Eight tools make more sense when you also have enough build volume and chamber capability to use complex multi-material jobs seriously.
The immediate question is no longer whether INDX is interesting.
It is whether you should buy this instead of an XL.
adidas is taking fully 3D-printed shoes mainstream
What happened
adidas unveiled the Futurecool, a seamless 3D-printed lifestyle shoe.
The first 400 numbered pairs are being offered through a CONFIRMED raffle. A broader worldwide release follows April 1, 2027 at €180.
Why it matters
The price is the story.
3D-printed shoes are not new. A fully printed shoe being positioned as a normal €180 retail sneaker is much more interesting.
That is additive manufacturing moving from “look what the technology can do” toward “this is simply how we make this product.”
Who should care
Material geeks, product designers, flexible-printing enthusiasts, footwear nerds, and anyone interested in where additive manufacturing becomes invisible.
Extruder Report verdict
This is more significant than another exotic one-off shoe concept.
The initial 400 pairs are marketing scarcity. The April 2027 mass release is the part worth watching.
Anycubic’s anniversary sale starts for real next week
What happened
Anycubic kicked off the warm-up for its 11th anniversary campaign.
The actual printer discounts arrive September 2. Until then, the company is running prize drawings, Makeronline challenges, extended benefits, and an upgraded 70%-off eligible 1kg material redemption for existing members.
Why it matters
If you are about to buy an Anycubic printer today, you have almost nothing to lose by waiting a few days.
Who should care
Anycubic shoppers, resin users, filament buyers, and deal hunters.
Extruder Report verdict
Do not buy an Anycubic printer this weekend unless the current price is unusually good.
Wait until Tuesday and compare.

Deal Pulse:
ELEGOO Centauri Carbon — around $300
The original Centauri Carbon is currently surfacing around $299.99.
That remains a lot of enclosed CoreXY printer for $300.
The catch: Make sure you are comparing the original Centauri Carbon, not the newer Carbon 2 Combo.
Also worth watching: Anycubic’s full anniversary pricing goes live September 2.
Community Pulse:
MakerWorld creators are worried the platform is rewarding low-effort content
One of the more persistent MakerWorld debates is still active this week.
Creators are complaining about copied designs, questionable remixes, fake or low-value print profiles, AI-generated hero images, and popular IP crowding original designs out of visibility and reward programs.
There is another side to this: flexi toys, fan models, remixes, and AI-assisted design are exactly how many beginners enter the hobby.
The reasonable middle ground seems simple:
Use whatever tools you want—but show the actual print, respect the license, and don’t pretend somebody else’s design is yours.
Print Farm Note:
Replacement parts beat random products
Thingiverse’s Spare Parts Challenge got 489 entries, and the winners were almost comically ordinary:
Tweezer tips.
A vacuum extension.
A microwave lever.
That is the lesson.
People do not search Etsy because they desperately want “a 3D-printed object.”
They search because they have a problem.
A cracked appliance part, discontinued knob, missing bracket, broken chair component, or awkward tool adapter already has demand built into it.
If you are looking for a product niche, spend less time asking:
“What can I print?”
And more time asking:
“What small plastic thing keeps breaking that nobody wants to replace the whole product for?”
Final Layer:
The best 3D-printing story this week might actually be a microwave lever.
Not because it is exciting.
Because it explains the value proposition perfectly.
A home printer can produce toys, art, props, shoes, eight-material masterpieces, and increasingly absurd multicolor dragons.
But the moment a 20-cent piece of plastic saves a $200 appliance is still the moment most normal people understand why having a tiny factory in the house is useful.
What to watch next week: Anycubic’s anniversary prices arrive September 2, and September is officially the month Bambu promised to reveal the R1.
The deal pages and the teaser page are both worth keeping open.
