Application Highlight: Scanning for Thermoforming

EmailFacebookLinkedInTwitterShare

In this blog, we’re going to take a closer look at an application that a scan-to-CAD workflow can really improve turnaround time on. Packaging manufacturers are tasked with creating packages that hold, protect, and display various consumer products. Two very common types of packaging include blister packs or clam-shell packaging. Though slightly different in their function, their manufacturing process starts out essentially the same. This where scanning can come in very handy. Both styles begin as thin plastic sheets that […]

Polyjet Accuracy: Matte vs. Glossy

EmailFacebookLinkedInTwitterShare

Anyone who has printed Polyjet parts can tell you there is a difference in geometry between printing the same part in matte mode vs glossy mode. However slight the difference is, running your fingers over the transitions between the two surfaces will tell you right away. It’s easy to tell that the matte surface is indented relative to the glossy surface. I’ve heard this aptly referred to as “puff out”, in reference to the support structure puffing out from the […]

Does a powder spray affect your 3D scanned measurement?

EmailFacebookLinkedInTwitterShare

In the past, 3D scanners have traditionally struggled with three main types of part surfaces, namely shiny, dark, and clear. Because these scanners are vision-based systems, if the cameras can’t detect the lasers being projected onto the part surface, we can’t collect any surface data. Each of these surface types interferes with scanning in their own way. Shiny parts reflect and scatter the lasers, dark parts absorb the lasers, and on clear parts the lasers simply pass through rendering the […]

In Depth Reverse Engineering Workflow Part 2 : Scan to CAD

EmailFacebookLinkedInTwitterShare

In the first part of this two part post, we took a look at the process for creating a 3D printable STL file from our scan mesh. This is great if you just need a copy of the part with no editing necessary. But what if you do want to edit the part? Then we will need to dive a little deeper into the realm of scan post-processing, and with a little extra elbow grease, we can create a parametric […]

Industrial Grade Vapor Smoothing with Stradivarius

EmailFacebookLinkedInTwitterShare

CATI has recently added a new FDM finishing machine to our Manufacturing Solutions lineup. The Stradivarius Vapor Smoother (more info at http://3dsmooth.com/) is a great piece of equipment for quickly and efficiently improving the look of FDM printed parts. It works by using acetone vapor to partially melt the surface of your FDM part (or some other chemicals depending on the plastic you want to smooth). This blends together the iconic FDM layer lines on the surface of your part, […]
