Stratasys Has Tough First Half, Looks Ahead To Future

Thursday, May 31st, 2018

Given enough time, virtually all companies experience ups and downs, highs and lows, and peaks and valleys. It goes without saying that these cycles are inevitable in the course of any business, and an industry that seems to have more than its share of major swings is additive manufacturing/3D printing, and a company that has had its share of these cycles of late is Stratasys.

As an example, this week, Stratasys Ltd. announced that Ilan Levin  decided to resign from his positions as CEO and Director, effective June 1, 2018.

Elchanan (Elan) Jaglom, the Company’s current Chairman of the Board, will serve as CEO until a successor is appointed. Mr. Jaglom’s service in the position of Chairman and CEO simultaneously requires shareholder approval in accordance with Israeli law. Stratasys plans to call a shareholder meeting to seek that approval. Mr. Levin will provide ongoing consultancy services to the Company following his resignation, as needed.

The Company’s Board of Directors has appointed an Oversight Committee to help support the management of the Company during the interim period, until a successor is appointed. The committee is comprised of the Company’s Vice Chairman of the Board, Executive Director and former CEO, David Reis, along with additional Directors Scott Crump, previous Chairman and Founder, and Dov Ofer.

Carbon 3D: Taking AM From Prototyping To Production

Thursday, May 24th, 2018

Carbon is an additive manufacturing system company that bridges hardware, software, and molecular science to further digital 3D manufacturing that goes far beyond prototyping. With Carbon’s Digital Light Synthesis (DLS) technology and its SpeedCell system, manufacturers can explore new business opportunities such as mass customization, on-demand inventory, and differentiated products made with unique functional materials.

Carbon’s vision is a future fabricated with light, where traceable, final-quality parts are produced at scale with Continuous Liquid Interface Production (CLIP) technology. CLIP is a fast photochemical process that eliminates the shortcomings of conventional 3D printing by using light and oxygen to rapidly produce objects from a pool of resin.

Carbon entered the market just over three years ago with its innovative resin-based 3D printing technology, bringing to market its first 3D printer, the M1, a year later. The SpeedCell system with the M2 3D printer and Smart Part Washer was introduced in 2017.

The Process

Despite industry advances, traditional approaches to additive manufacturing force trade-offs between surface finish and mechanical properties. In contrast, DLS (Digital Light Synthesis) technology, enabled by Carbon’s proprietary CLIP process, is a unique technology that uses digital light projection, oxygen permeable optics, and programmable liquid resins to produce parts with excellent mechanical properties, resolution, and surface finish.

Traditionally 3D printed parts have been notoriously inconsistent. Conventional 3D printed materials often exhibit variable strength and mechanical properties depending on the direction in which they were printed. DLS parts behave consistently in all directions. The resolution and gentleness of the process — where parts aren’t harshly repositioned with every slice — make it possible to exploit a range of materials that have surface finish and detail needed for end–use parts.

CLIP is a photochemical process that carefully balances light and oxygen to rapidly produce parts. It works by projecting light through an oxygen-permeable window into a reservoir of UV-curable resin. As a sequence of UV images are projected, the part solidifies and the build platform rises.

The heart of the CLIP process is the “dead zone” – a thin, liquid interface of uncured resin between the window and the printing part. Light passes through the dead zone, curing the resin above it to form a solid part. Resin flows beneath the curing part as the print progresses, maintaining the “continuous liquid interface” that powers CLIP.

Once a part is printed with CLIP, it’s baked in a forced-circulation oven. Heat sets off a secondary chemical reaction that causes the materials to adapt and strengthen.

ESPRIT CAM Software: Smart Machining From The Cloud To The Manufacturing Floor

Wednesday, May 9th, 2018

DP Technology and its ESPRIT CAM System deliver a wide range of machining solutions for Industry 4.0 smart manufacturing.

DP Technology Corp is a privately held company co-founded in 1982 by Daniel Frayssinet and Paul Ricard. The company gets its name from the first names of the co-founders – (D)an and (P)aul. The company’s corporate headquarters is in Camarillo, California. The rest of the company is structured by function with offices in France, Germany, India, Italy, China, and Japan.

DP Technology is the developer of the diverse ESPRIT CAM System sold and supported via the company’s regional offices and its network of resellers around the world. ESPRIT has also developed close partnerships with several leading milling, turning, and wire-EDM machine tool manufacturers, including Okuma, Mazak, DMG Mori, Citizen, STAR, Mitsubishi, GF AgiCharmilles, Doosan, and Tsugami, just to name a few.

ESPRIT literally gets its name from the French noun, esprit de corps, that translates to spirit of a body of persons or group spirit; sense of pride, honor, etc. shared by those in the same group or undertaking.

DP Technology develops CAM software for a full range of machine tool applications. ESPRIT CAM, DP Technology’s flagship product line, is a full-spectrum programming system for milling, turning, wire EDM, and multitasking machine tools. ESPRIT’s data exchange functionality reads data from most native formats, including Autodesk Inventor, CATIA, SOLIDWORKS, Solid Edge, NX, ACIS, and Pro/ENGINEER (Creo). DP Technology also provides complementary add-ins for several CAD programs.

DP Technology continually reinforces its commitment to its technology and customers by dedicating approximately 25% of its annual revenues to ongoing product research and development. According to Don Davies, VP of Americas, DP Technology Corp., the company also has what he called “shadow R&D,” who are application engineers in the field developing post processors and simulation solutions with machine tool OEMs and dealers.

When asked about the state of the CAM market, Davies said that it is largely fragmented into distinct segments – integrated CAD/CAM vendors, such as Dassault Systemes, PTC, and Siemens PLM Software; and independent CAM vendors, such as DP Technology, Mastercam, and other VAR-based dealers. He said each has its own advantages but thought that the dedicated efforts that independent companies specializing in CAM bring the most to the table, and obviously, he felt that DP Technology had the ability to serve up the most comprehensive product/technology lineup in the competitive CAM market.

DP Technology is helping manufacturers prepare for the digital transformation that’s taking place in manufacturing, with solutions including digital twinning, digital threads, machine-aware manufacturing, knowledge-based machining, and cloud-enabled databases.

To prepare manufacturers for an increasingly digital future, and to better support Industry 4.0 and smart manufacturing initiatives, DP Technology is focusing on a range of solutions to drive automation in manufacturing. The ESPRIT CAM System enables manufacturers to streamline workflows, prevent silos from forming during the manufacturing process, increase tool life and machine utilization, and create greater access to practical knowledge for process improvement.

Wohlers Report 2018: AM Grows Overall With Metal Rising

Thursday, May 3rd, 2018

An independent consulting firm and industry source that we know quite well, Wohlers Associates, Inc., recently released the Wohlers Report 2018, the company’s annual detailed analysis of additive manufacturing (AM) and 3D printing worldwide.

Wohlers Associates is widely recognized as the leading consulting firm and foremost authority on additive manufacturing and 3D printing. This annual publication has served as the undisputed industry-leading report on the subject for two decades. Over the 23 years of its publication, many (including me) have referred to the report as the “bible” of additive manufacturing (AM) and 3D printing—terms that are used interchangeably by the company (and industry).

Wohlers Report 2018 is filled with insightful data and perspective to inform readers of the most critical developments in the industry. According to the new report, an estimated 1,768 metal AM systems were sold in 2017, compared to 983 systems in 2016, an increase of nearly 80%. This dramatic rise in metal AM system installations accompanies improved process monitoring and quality assurance measures in metal AM, although more work is ahead. Increasingly, global manufacturers are becoming aware of the benefits of producing metal parts by additive manufacturing.
