FFF: Nozzle Sizes Demystified

Nozzles can be a confusing topic in 3D printing, mainly because it feels intuitive that a smaller nozzle sizes would provide for a better finish.  This is simply not true.

When thinking about nozzle size there are really 2 things to consider...

You like HP MJF parts? Then you will LOVE Sintratec Desktop SLS parts!

If you have been watching the 3D printing industry at all over the last year, you could not miss the appearance of HP in the 3D printing market.  Frankly, the quality and surface finish on thesep arts is fantastic. There is a drawback though...the machines are super expensive (think north of $100k) and the parts printed as a service are not a bargain either, as most service bureaus are charging a premium for access to this new printer.

Optimize for STRENGTH with Simplify3D & German RepRap 3D Printers

There are many characteristics to consider when optimizing for strength.  Obviously, this is highly dependent upon the material properties of your filament.  It is also highly dependent on the number of shells in the part, the infill shape, and the infill density.

Optimize for SPEED with Simplify3D & German RepRap 3D Printers

To optimize for Speed on a German RepRap printer, you need to consider the layer size (similar to optimizing for surface finish...only opposite). ...

3D Scan to CAD - Workflow Explained

Many of our customers who purchase 3D Scanners are interested in generating STEP data to import into their CAD system of choice (Solidworks, Creo, ProE, Inventor, etc).  Often, these customers are surprised to learn that CAD formats (STEP, IGES, etc) are a standard output format for 3D scanners. 

Optimize for SURFACE FINISH with Simplify3D & German RepRap 3D Printers

We can optimize surface finish on any German RepRap 3D Printer with Simplify3D (our slicer software).  Surface finish is a function of layer size and nozzle size. The smaller both are, the better it looks. The tradeoff is print time, the smaller the layer and nozzle size are, the longer it takes to print.

Desktop SLS for FabLabs, Makerspaces & Innovation Studios

SLS (Selective Laser Sintering) 3D Printers have been available for years, but typically command huge price tags in the $100k-250k range.  With that introduction of Desktop SLS 3D printing, a new era of 3D printing capabilities is upon us, for a price tag less than $6k.

Does a Heated Chamber really matter?

To be fair, it only matters if you want to print materials other than PLA and PETG.  At 3DChimera, most of our customers are engineer's and those ...
