The Ultimate 3D Printing Match Up: Laser Sintering vs. Fused Deposition Modeling

Laser Sintering (LS) and Fused Deposition Modeling (FDM) are like the Peyton Manning and Cam Newton of 3D printing—Two of the best quarterbacks in the league, one about ten years older than the other (LS was commercialized in around 1980 and FDM around 1990), and currently both at the top of their game. LS and FDM are often compared because they both deliver similar materials and engineering-grade thermoplastics which give them the ability to serve functional and production manufacturing applications. Even though LS and FDM are equally capable of producing strong, durable parts, their divergent delivery mechanisms make certain geometries and applications better suited for one or the other. Learning the advantages and differences between technologies will help lead you to the best process for your project. Here we compare each technology when it comes to engineering challenges, applications and geometries:

Five 3D Printing Tips to Save You Time

3D printing is known to be a fast alternative to most traditional manufacturing processes, and you can harness the possibilities of this groundbreaking industry by taking some easy steps. Get to market quickly with these five tips to save you time when ordering 3D printed parts.

1. Export Your CAD file as a STL In order for a 3D printer to build a part, the CAD file has to be exported into a STL file. A STL file is made up of triangles forming the surface of the part, causing faceting of the 3D model. Depending on the parameters set up, the faceting of the 3D model will differ. Common parameters that affect faceting of STL files include chord height, deviation, angle tolerance and poly count. It’s imperative to prepare your files for the export with this in mind to ensure quality expectations and design intentions are maintained from CAD to final part production.
There are a number of ways to optimize and prepare your CAD data to guarantee ­files are ready for processing and productio…

F1 car scanned with Artec Eva, reverse engineered and 3D printed

It’s amazing what you can do with a combination of 3D scanning and reverse engineering solutions. This project for scaling down a full-size Formula 1 racecar, for which Artec Eva 3D scanner was used, is one of the many examples showing that 3D tech application opportunities are, indeed, limitless.

The project was initiated by a Birmingham-based tool manufacturer that tasked Artec’s British partners Central Scanning and leading supplier of CAD & CAM solutions Delcam with making a scale model of their F1 car so it can be 3D printed at a size of approximately 300 mm.

The car was 3D scanned by Central Scanning, and then the collected data was modeled in Delcam’s reverse engineering software package PowerSHAPE.

“This scan was done by us as a test to see what could be achieved using two types of scanning systems,” said Paul Smith of Central Scanning.

The main body of the car was scanned using Steinbichler Comet L3D scanners, and then the driver’s cockpit, steering wheel, wishbone suspen…

3D Scanner cast in starring role at leading foundry

It’s always great to get testimonials from industry pros who have enhanced their performance thanks to Artec 3D scanners. One such company is Willman Industries Inc., a Wisconsin-based full-service jobbing foundry offering design, pattern making, heat-treating and machining.

Willman were already familiar with the benefits of 3D scanners as they were looking to upgrade from an older laser scanner and Faro arm. Efficiency working with large castings up to 30,000 pounds was the benefit that sold them on the Eva, says Steve Young, the owner of Exact Metrology.

“With the larger castings, the [Artec] scanner can be taken to the casting rather than having to move the casting to where the scanning arm is,” explains Dana Green, an account manager at Exact Metrology. “That along with the large field of view allows for faster capture rates compared to that of the arm and scanner. Additionally the accuracy tolerances are well within the Eva’s capabilities.”

Since its purchase, says Randy Parker,…

Top 5 3D Printing Misconceptions

Given the roller coaster of attitudes towards 3D printing in recent years, it can feel like there is a plethora of misinformation on the technology. Misinformation has led to misguidance, misuse and ultimately distrust. To fully embrace 3D printing in all its varied forms, and therefore achieve the greatest overall value from what could be a crucial project solution, we’ve gathered some of the most common misconceptions we’ve heard from newcomers and industry veterans alike and addressed where the misconception comes from and how 3D printing breaks the mold.

Misconception 1: 3D printing can’t produce real functional parts. This misconception stems from early realities for the technology. In the first decade or so, 3D printed plastics were mostly relegated to photocure materials which were not durable. Most 3D printing processes did not have good tolerances or automation in place to aid in controlling the build to achieve a specific need. By about 2000, however, 3D printing was already …
