Welcome to the world of Rapid Prototyping.

Perform an on-demand comparison of different RP technologies before making your next important project. Choose up to four of the listed technologies to see a more detailed comparison of their attributes and capabilities. FineLine does not offer part production in all of these technologies — we merely present them to you for the sake of comparison. Enjoy, and please contact us if you know of a technology that we should add to this list.

Technology	Overview	Features	Sample	Compare
Reference CAD Data	CAD Model These are shaded images of the CAD data — it doesn’t get any better than this!	Perfect, with proper file translation
Stereolithography	Viper HR FineLine’s signature offering. The dominant technology for accurate, richly-detailed small parts in a variety of materials.	Smooth surfaces Very fine detail
	Viper NR Not as crisp as the Viper HR, but allows for making larger parts at lower cost.	Smooth Fine detail
	iPro The latest equipment in stereolithography, this machine does large parts at higher quality and resolution than ever before.	Smooth Fine detail
	SLA 5000 While similarly fast as the iPro, does not produce at nearly as high a quality due to its optical configuration.	Fast build
3D Printing	InVision HR Multiple jets image in raster fashion to deposit UV-curable liquid. Can also be investment cast, so it is a great choice for jewelry or small medical devices.	Fine detail all over Low strength
	InVision SR Uses multiple-jet imaging like the HR, but is a fast-building machine intended for quick concept models at lower resolution.	Medium detail Low strength
	ZCorp Some ZCorp machines can make multi-colored parts by jetting colored binders. Not known for fine details, but can attain remarkable toughness with post-build infiltration.	Color capable Rough finish
	PolyJet Primarily for concept modeling applications. Uses industry-leading thin layers for great Z-axis resolution, but lower in X and Y. Slightly rough surface finish.	Fast Great Z-res So-so XY res
Selective Laser Sintering	SinterStation Pro Uses a laser to fuse layers of thermoplastic powder. Vector-based, so it can be quite accurate, and very strong, but has a rough surface and lacks fine details.	Engineering materials
Fused Deposition Modeling	Dimension Elite Melts and extrudes a filament of thermoplastic through a tiny nozzle. Strong in 2 out of 3 axes (layer adhesion is inferior), but lacks resolution and accuracy of small features.	Engineering materials
Perfactory	Mini Uses digital light projection technology to image a liquid photopolymer. Capable of fine details, but number of parts per build suffers.	Very fine detail Small build area
