![I Engraved a 3D Sculpture INSIDE Glass β ComMarker Omni X UV Laser Review
*** Use code christopherhoff for 5% off your order! ***
The ComMarker Omni X is a fully enclosed UV laser engraver that works on metal, wood, acrylic, leather, stone, glass, and can even engrave 3D sculptures inside solid crystal blocks. In this review I put the 6W version through a full month of real-world testing, covering everything from internal glass engraving and metal oxidation colors to wood cutting and leather work. Ill also walk you through the LiDAR autofocus, dual lens system, ComMarker Studio software, and Lightburn compatibility, plus one hardware issue I ran into and how ComMarker handled it. If youre considering a UV laser and want to know if the Omni X justifies the price, this is the video for you.

![I Spent $227 on Formlabs Form Now... Heres What Showed Up
*** The first 100 people can use code Hoffman-10 for 10% off your Form Now order! ***
Formlabs just launched Form Now, their new print-on-demand service that prints your models in resin or SLS nylon and ships them straight to your door. I put it to the test by ordering a mix of their sample parts and my own designs, focusing on nylon SLS prints since I dont have access to an SLS printer at home. In this video I walk through the entire experience: uploading models, picking materials, getting instant quotes, and unboxing the results. My order ran $227 with shipping and tax, and the parts showed up in 11 days. I hit a couple of snags along the way, including a missing part and some tolerance issues on parts I designed for FDM, and I cover how Formlabs handled it. If youre curious whether a U.S.-based print service is worth it for one-off parts or production runs, this is my honest take as a first-time customer.
Since I tried out the service at launch in early April, theyve made a number of improvements. According to the Form Now marketing manager:
1. Part Pricing: weβve made some factory optimizations and pricing improvements to pass on the savings to our customers
2. Shipping Pricing: Shipping calculations are now dynamicly calculated, and are no longer a $20 flat-rate shipping. This means smaller orders can be a lot cheaper to ship now than before.
3. Individual Packing: Parts are now individually wrapped and labeled to prevent damage during shipping.
Im glad to see Form Now continue to evolve, and well see if I have the opportunity to test them out again in the future.

![Can a $499 CNC Really Cut Aluminum? | Axiscreat i3030 Full Review
In this video, I review the Axiscreat i3030 CNC router; a compact but powerful machine designed for hobbyists and small workshops. With its 710W spindle, rigid frame, and automatic Z-probe, the i3030 makes cutting wood, engraving details, and even machining aluminum surprisingly easy. After a month of hands-on testing, Iβll walk through its setup, performance, pros and cons, and show real-world cutting examples so you can decide if itβs the right CNC for your shop.
