CNC Milling Machine

3D printing + CNC milling – Worth the effort?

Teaching Tech

January 5, 2023



3D printing is accessible, but has its drawbacks. CNC milling for most is harder to set up, butoffers great precision at the cost of inefficient and wasteful subtractive manufacturing. What if we 3D print an oversized model, and then mill it down to the final shape, eliminating layer lines and other imperfections? In this video I experiment with this concept on an F1 in Schools wheel.

I think everything was a win apart from the surface finish. More experimentation with spindle rpm, feed rate and cutting depth could yield better results. Also me having more patience with sanding and polishing at the end would surely help too.
Is this all just a waste of time or are there suitable applications?

CNC Router

CNC router for $200 – Sainsmart Genmitsu 3018 Pro review and tutorial

Teaching Tech

October 31, 2022



3D printing has become much cheaper and accessible, but there has been a lack of decent CNC routers at the same price point. Now the 3018 CNC Pro from Sainsmart aims to fill that void.

Featuring a working volume of 300 x 180 x 45mm, this CNC router goes together well and is capable of machining timber, acrylic and aluminium. It can also engrave copper to make custom PCBs. This machine largely succeeded with everything I threw at it. For this low price plus a one year warranty, I am very impressed and recommend this for beginners looking to get into the hobby.

I have done a fair bit of CNC machining over the years by am by no means a professional machinist. I look forward to the great tips knowledgeable viewers will post in the comments to assist others.
For any cutters you buy, ensure they are 1/8 inch or 3.175mm in shank diameter.

UPDATE: I have a follow up video upgrading this machine. https://youtu.be/Q4TrzshXV10
