I want to start my 3d business next month and I have only one choice. Do I start with Ultimaker 3 extension or form 2. When my business grow up I will buy more 3d printers, but now what is the best choice start with.
Let me ask you a few questions in return. Do you have a market with consistent, paying customers for 3d printed goods? If so, what kind of 3d printed goods are customers more interested in? Given your answer, which printer would fit best for your customer’s needs? The Ultimaker or Form 2? Maybe those questions would be a good starting point in determining the viability of your 3d printing business.
Start with one printer then use that to MAKE more printers.
If you are new to 3D printing and you are new to 3D design, you are going to have a very steep learning curve. The biggest gap with 3D printing is the skillset needed to manipulate the data you will be feeding the thing. You can’t just print stuff off of Thingiverse and expect to make money. The biggest service you could provide your customers would be walking them through the process that takes their ideas, interprets them into input for your 3D printer and produces stunning, impactful and (mostly) accurate parts. Ultimaker is good, but you could be just as successful for 1/3 the price with a genuine Prusa i3.
The bottom line, however, is that you need to be VERY familiar with working in 3D and understanding the language a 3D printer uses. Especially if you are trying to do this as a service. Also consider getting a 3D scanner, though that adds another level of complexity when working with 3D files.
