How does 3D printing compare with other rapid prototyping technologies?
What about production speed though, is 3D printing technology also superior in this regard or is it one of the few downsides? I’ve used rapid prototyping services in the past and whatever I have ordered usually arrived in a couple of days, so now I’m curious if 3D printers are faster than that. I’ve been thinking about starting a business to assemble braking systems for cars and this post really got me thinking on which manufacturing method to choose.
3D printing technology is cheaper, faster and more accurate than SLA and SLS machines, and with the added bonus of no nasty chemicals, powders or resins to handle it is better for the environment as well. A typical SLS machine uses a layer size of 0.15mm whereas the Objet technology uses a 0.028mm layer size (that’s about half the thickness of a human hair!) so the resulting surface finish is superior to SLA & SLS technologies. FDM on the other hand uses a 0.25mm layer size but uses an ABS plastic material which is ideal for living hinges and click fittings. Also SLA & SLS machines can only produce parts in one colour, whereas the Z Corp machine is unique in that it can print in multiple colours on the same component. Each 3D printing technology has its advantages and disadvantages so have a look at our materials page to determine which technology will be best for your project.
