Hey fellow makers! 👋 By day, we’re a group of aerospace engineering students at TU Delft, but by night, we’re makers who have been in the 3D printing space since 2016. Like many of you, we’ve always struggled with one existential problem: the air quality in our workspaces. We noticed that printing with materials like ABS, PETG, and even PLA releases fumes, ultrafine particles (UFPs), and VOCs that linger in the room. We searched for a solution, but most enclosures on the market were either niche to specific printers, sacrificed build quality, or were simply too expensive. So, we decided to build our own. Meet Clura—a modular, smart, and completely open-source 3D printer enclosure. This awesome project is now live on kickstarter (fully funded in 58 minutes!) This is the link: https://www.kickstarter.com/projects/clura/enclosure We wanted to create something that actually protects your health while optimizing the printing process. Here is what we integrated into the design: Air Filtration: It uses high-performance fans with dual-layer HEPA and carbon filtration, capable of filtering the entire enclosure volume in just 60 seconds. Smart Sensors & Fire Safety: We packed it with a dedicated sensor suite. It uses a BME680 for temp/humidity/VOCs and a PMS5003 for particle tracking. For safety, it combines an MQ2 gas sensor with MEMS and optical smoke sensors to detect thermal runaway or fires instantly. Filament Weight Tracking: We integrated HX711-based load cells into the spool holders to track filament weight in real-time. No more guessing if you have enough plastic to finish a print! Universal Fit: Because it's modular, it currently fits the Prusa MK3/MK4, Bambu Lab A1/Mini, Prusa Mini, Ender 3 style bed slingers and so much more... Our 100% Open-Source Promise We are firm believers in the open-source community. Every CAD file, software component, and build guide is free and released under the CC BY-NC license. (links on docs.clura.dev) You can self-source the parts and build it yourself, customize it, and even submit your own mods to our Community Upgrade Center. You own it completely. No vendor lock-in, ever. The kits we offer are just a convenient way to assemble it by supporting the project while saving time and money in the process. We'd love to hear your feedback! Happy printing! 🛠️

Step 1: Draw a construction circle at the Origin. Mark A, B, C where the circle meets the Y and Z Axis as seen above. Draw the half circle at the origin between A and B. Step 2: Draw a construction circle at the Origin. Mark A, B, C where the circle meets the Y and Z Axis as seen above. Draw the half circle at the origin between A and B. Step 3: Draw an arc centered at C between D-E: 🥚 Good job!The full tutorial project is available at Printables with the finished 3d model and FreeCAD file: https://www.printables.com/model/1615557-egg-tutorial-model

This online calculator will help you estimate the costs involved in creating a 3D-printed object, taking various factors into account. 💰 https://3dwithus.com/3d-print-cost-calculator If you need to justify your 3D printing hobby at home, here’s a handy electricity cost calculator 😉 Spoiler: it doesn’t use as much power as you might think. For UK folks, it’s even more reasonable. ⚡https://3dwithus.com/3d-printer-electricity-cost-calculator We will be getting more handy tools to fill our Interactive Tools & Calculators category. Any requests? Do you have interesting examples of 3D printing costs? Share them here.

I was invited to contribute to the 3D Printing Industry 2026 Executive Survey. Based on what I see daily in the personal and prosumer market, here is my perspective on where 3D printing is heading: AI generators made a noticeable leap last year, and in 2026, this trend will continue with further optimization and wider adoption. What is especially interesting is how quickly chat-based AI tools are starting to generate simple, printable 3D models. While still basic, these tools are already lowering the barrier to entry, and in 2026 we will see more users actively relying on AI not just for ideas, but for producing usable starting points for 3D printing. Another trend that will clearly carry over into 2026 is the success of tool-changer systems in the personal and prosumer 3D printing segment. What proved itself in 2025 will not be ignored by the wider market. More brands are expected to introduce their own versions, as the benefits are difficult to overlook: significant material waste reduction, faster multi-material workflows. Finally, toward the end of 2025, we saw increasing investor confidence and substantial funding flowing into Chinese personal 3D printing companies. While 2026 may still be too early to judge the full impact, it is reasonable to expect the first results of this investment. It can be seen as faster product iteration, tighter hardware-software integration, or more aggressive market expansion.

Hi Everyone! I would like to showcase the result of my latest project: A parametric Anti Sphere Pot They are made by carving out a cylinder using spheres placed in circular and linear patterns. These patterns can also be twisted around the Z-axis, resulting in some truly unique designs! Here are some of the pots i created with it: You can check out and download the demo models on Printables for free. The FreeCAD project file is not yet available (needs some polishing). Since i am not a good photographer, i edited these pictures with the help of AI. You can still view the original photos on the demo's page. I hope you like it :)

Here is one of the models, 3D printed on Creality K2 Pro in engineering-grade material PA12-CF. Looks nice, and the finish resembles popular galaxy composite filaments. This Anti Sphere - looks great. This is the default size. For functionality, I would print it bigger and with a larger nozzle.
