Big week at Mr Resin: we're turning two years old. And we're celebrating the right way — with 15% off resins and filaments, already applied. But the hobby world doesn't stop: the HeyGears G1X finally launched its Kickstarter with real pricing, there's a free full-color printing tool, Hackaday revisits resin printing six years later, and a European project is 3D printing living bone and muscle. Let's go. 🔥
📚 Mr Resin Special
🎂 Mr Resin Turns 2 (and we're celebrating with you)
Two years ago, Mr Resin was little more than an idea, a printer, and a whole lot of passion. Today we're the go-to 3D printing store for thousands of makers across Spain, an official distributor for Elegoo and Anycubic, and a community that just keeps growing — all because of you.
The numbers still feel surreal: over 5,000 makers have trusted us for their resins, filaments, paints, and tools. More than 400 verified reviews with an average that honestly makes us blush. Nearly 6,000 people open this newsletter every Monday. And a Telegram community that answers questions, shares prints, and keeps the conversation going at all hours. This isn't just a store — it's a place built around a shared obsession.
So to say thank you the right way, we've activated a 15% discount across all resins and filaments, already applied directly in the store — no codes, no hassle. It's our way of saying "thank you for two amazing years" and helping you stock up for the summer. Take the chance to restock that resin you're running low on, or finally try that filament you've had your eye on.
Two years is a lot: hundreds of orders, containers shipped across the world, guides, tutorials, this newsletter week after week... and the best is still to come. Thank you for being part of the journey. This one's for you. 🥂 Shop resins with 15% off → · Shop filaments with 15% off →

🖨️ The HeyGears G1X Is Live on Kickstarter (with real pricing)
Remember the HeyGears G1X — the printer that outputs full-color 3D objects and that we covered back in #014? After months of teasers, July 23rd it finally launched on Kickstarter with real numbers on the table. This is no longer a promise — it's a live campaign.
One important distinction worth repeating, because it matters: the G1X is NOT a vat resin printer like your Saturn or Mars. It uses UV inkjet technology (material jetting) — an industrial Epson i3200 printhead that fires CMYK + white + clear ink droplets and cures them instantly, building full-color 3D parts with gradients and transparency, straight off the printer, no painting required. Build volume up to 420×330×130 mm with water-soluble supports.
What about pricing? The Super Early Bird starts at $1,999 for the base G1, but here's the catch: the model that delivers true full-color 3D is the G1X Full-3D Pack at $3,599 (MSRP $5,499), with bundles going up to nearly $11,000. Shipping is expected "in 2026." As always with crowdfunding: cautious optimism. This is a campaign, not a storefront — specs are self-reported and no independent reviews exist yet. But the fact that the promise of "full-color minis without a paintbrush" finally has a price tag and a timeline is a big deal. We'll be keeping a close eye on this one.

💻 Software
🌈 Lumina Studio: full-color FDM printing, free and open source
If you want color prints without dropping $2,000 on a new machine, this one's a gem. Lumina Studio is a free, open-source tool that converts any image into a full-color FDM print by using the way light passes through thin layers of filament.
The approach is clever: you print a calibration chart with 1,024 color combinations (blending four filaments across different layers), photograph it, and the software learns exactly which real-world color each combination produces on YOUR printer with YOUR filaments. From there, it maps any image to that palette and exports a 3MF file ready for Bambu Studio or OrcaSlicer. It supports 2- to 8-color setups.
What really stands out is the philosophy: free, open-source, no telemetry, no lock-in. No complex color theory, no platform dependency. It's exactly the kind of community-driven project we love — very much in the spirit of the HueForge fork we covered in #002. The community, building things for everyone. Read more at Fabbaloo →

🧪 "I came back to resin printing after six years": a Hackaday retrospective
This one will hit close to home. Hackaday published a first-person account from someone who returned to resin printing after six years away — six years of avoiding the smell, the IPA, the gloves, and the cleanup nightmare. They dusted off an old Creality LD-002R and took stock of how much things have changed.
It's a great read for anyone in the hobby, because it hits every nerve: the love-hate relationship with resin, that mix of "the detail is unreal" and "cleaning this up is a nightmare." Spoiler: mono MSLA printers have come a long way — better resolution, faster print times, longer-lasting screens — and the overall experience today is far more approachable than that first generation ever was.
We're sharing this because it perfectly mirrors the experience of so many people in our community: that on-again, off-again relationship with resin printing. If you walked away from it at some point and you're thinking about giving it another shot, consider this your nudge. Today's resins are nothing like they were six years ago — we promise — and if you need resin or a wash and cure station to make that comeback as smooth as possible, you know where to find us.

🤖 WTF Science
🦴 A European Project Is 3D Bioprinting Living Bone, Fat, and Muscle
We're closing out with some genuinely exciting science — with a European flavor. The PRISM-LT project, funded by the European Union through the European Innovation Council, has developed a bioprinting method capable of generating living tissue: bone, fat, and muscle.
The research is led by Massimo Vassalli, Professor of Bioengineering at the University of Glasgow, as part of a five-year initiative running through 2027. The core goal is to create functional "living materials" through printing — a rapidly evolving field with the potential to transform everything from regenerative medicine to drug testing without animal models.
This is the latest milestone in a story we've been following all year, from the 3D-printed cornea in issue #010 to bioprinting on the ISS in issue #017. And this time it's flying the European flag, which is always a welcome sight. The same technology we use for miniatures and prototypes, pushing the boundaries of what's possible.

💬 Our Take This Week
It's been a great week for looking both backward and forward. Backward: two years of community, orders, and lessons that have brought us to where we are today. Forward: an industry that never slows down — color is breaking through (via Kickstarter and free tools), resin printing keeps winning back everyone who returns to it, and science keeps pushing boundaries that not long ago seemed out of reach.
Thank you for these two years. For the questions you've sent us at midnight, for the photos of your prints, for trusting a small shop that puts its heart into every order. We're heading into year three more motivated than ever. And remember: this month, resin and filament are 15% off to celebrate. 💪🥂
❓ This Week's FAQ
What does the Mr Resin anniversary discount include?
To celebrate our second anniversary, we're offering 15% off our entire range of resins and filaments. The discount is already applied directly to the prices in the store — no coupon code needed. It's a limited-time celebration deal, so it's a great time to stock up on materials.
Is the HeyGears G1X a resin printer?
Not in the traditional sense. While it does print full-color 3D objects, it doesn't use a resin vat and LCD screen like typical MSLA printers (Elegoo Saturn, Anycubic Mars, etc.). Instead, it works via UV inkjet (material jetting): a print head fires and cures droplets of photopolymer layer by layer. Its Kickstarter launched on July 23, 2026, with prices starting at $1,999 — though the model capable of true full-color 3D printing costs considerably more.
Can you 3D print in full color without buying a new printer?
Yes, using a standard FDM printer combined with software tools like Lumina Studio, which is free and open-source. These tools take advantage of how light passes through thin layers of different filaments to simulate continuous color, and they work by physically calibrating which color each filament combination produces on your specific machine. The output is then exported to slicers like Bambu Studio or OrcaSlicer.
Have resin printers improved significantly in recent years?
Absolutely. Today's monochrome MSLA printers offer higher resolution, faster print speeds, and more durable LCD screens than those from five or six years ago. On top of that, the accessories ecosystem — wash-and-cure stations, reformulated low-odor resins — makes the whole experience much cleaner and more user-friendly than early-generation machines. For miniatures requiring maximum detail, they still offer the best quality-to-price ratio on the market.
