Viridis3D Launches RAM10™ 3D Printer Materials Development Kit!

Viridis3D LLC has released an open materials development system designed to make R&D fast, cheap, and easy – called the RAM10™ 3D Printer Materials Development Kit.

The new RAM10™ Materials Development Kit is very simple in construction and has very fast test cycle times with a small build volume and includes: fluids manifold, electronics, and spreader bars. The RAM10™ uses ViriPrint™, which is the same software as the production printers.

According to Viridis3D CTO, Jim Bredt, “Viridis3D has taken a very different tactic from the older large format printer manufacturers. The RAM10™ 3D Printer Development Kit allows users to change powder, binder, firing parameters, tubing, and powder deposition subsystems — enabling distributed development of new materials sets. The similarities allow scale-up to the larger systems to be as seamless as possible.”

“We’re very eager to see the products that come out of the academic and industrial sectors as they start to use this materials development system,” said Will Shambley, President of Viridis3D. We’re hoping that by making this easy-to-use development kit, that we will be able to create a thriving development community around the bigger production RAM printers.”

The first system was installed recently at Palmer Manufacturing & Supply, Springfield OH. Ken Strausbaugh’s efforts on binder research were quickly rewarded. “It was extremely easy and fast to get the RAM10™ up and running. With a little guidance form Viridis3D, we had a new ink working in just a few days,” said Strausbaugh.

Overview of 3D printing technologies

Professional 3D printing or additive manufacturing refers to several technologies that produce parts in an additive way. The table above provides an overview over the technologies by the type of material they work with (vertical axis) and how the parts are built out of this material (horizontal axis).

Additive manufacturing, or professional 3D printing, refers to several technologies that produce parts in an additive way. Starting point is a digital 3D model of a part, which is then “sliced” in thin layers by a specific computer software. An additive manufacturing machine is building these layer on top of another and thus is creating the physical part.

ExOne’s Cold-Hardening Phenol Binder in Production Now

The ExOne Company’s “cold hardening phenol” (CHP) binder agent is now in commercial operation on a machine in Freiberg, Germany, for prototype casting producer, ACTech GmbH. It is the first 3D printer in the world using the new binder, which was first reported last September as a further development of the phenolic binder formulations ExOne debuted in 2013.

According to the developer, ACTech is able now to produce prototypes of challenging designs more quickly and cost-effectively. “Compared to traditional rapid prototyping procedures, this new technology enables the production of high-strength molds and cores for sand castings, which until now were achievable only with laser sintering,” according to an ExOne announcement.

UMWELTFREUNDLICHER 3D-DRUCK

Auf dem Weg zu nachhaltigen, energie- und ressourceneffizienten Prozessen rücken die anorganischen Bindemittel in der Gießereibranche immer stärker in den Mittelpunkt von strategischen Entscheidungen.
voxeljet und Hüttenes-Albertus ist es erstmalig gelungen, anorganisch gebundene Formen und Kerne werkzeuglos im 3D-Druckverfahren herzustellen.
Damit ist das umweltfreundliche 3D-Drucken ein weiterer, konsequenter Schritt zu einem vollständigen Produktionsprozess ohne Umweltbelastung.

Spanplatten und andere Holzwerkstoffe

Das Grundmaterial für Spanplatten sind holzhaltige Faserstoffe. Überwiegend handelt es sich um Industrieholz (Sägewerks- und Hobelreste), Altholz, Bau- und Restholz sowie Schwach- und Durchforstungsholz. Da diese “Rohstoffe” nicht immer herkunfts- und sortenrein getrennt werden, können auch mit Holzschutzmitteln belastete Hölzer in die Produktion und anschließend in Häuser und Wohnräume gelangen.

ExOne Binders

ExOne® binders are central to the printing process. The type of binder used depends on the type of powder or system that is being used, or customer application requirements.

Furan Binder

Furan binder is a typical no-bake binder found in traditional sand casting applications, and therefore no foundry changes are required to utilize this binder material. Printed cores are  immediately available for casting with no heat required.

Phenolic Binder

Utilized for printing sand molds and cores, phenolic binder is the best suited for high temperature pouring of castings. Very thin walls or thin pipes can easily be printed, due to the high heat strength of the core. Parts are easily cured using microwave technology.

Silicate Binder

ExOne offers an innovative environmentally-friendly option, with a binder based on silicate for printing sand molds and cores. Using this binder for printing results in low gas emissions during the casting process. Parts are easily cured using microwave technology.

Aqueous-Based Binder

Many of our directly printed materials (primarily metals) utilize a proprietary aqueous-based binder, which acts as an adhesive, bonding layers of powdered metal together. Once the parts are printed, they are placed into a furnace and the binder is burned out of the parts while powder particles fuse together in a sintering operation.
