ADVANCED ADDITIVE MANUFACTURING MIXER
FOR METAL, CERAMIC, AND POLYMER FEEDSTOCK

AIP Advances

“Homogeneity of the bonded magnet was accomplished by thoroughly mixing nylon and magnet powders using the LabRAM, Resodyn Acoustic Mixers prior to the compression molding. Mixing both components in powder form helped overcome the agglomeration difficulty during the magnetic field alignment process.”

Material Processing

“We have developed a game-changing approach for additively manufactured extreme lattice metamaterials... . In particular, this chain includes combination of a set of techniques:... the resonant acoustic mixing of all nanocomponents, growing the high-end ELM elements by high-precision multi-material additive manufacturing as well as using the data-driven digital twins-based nanoscale manufacturing approach.”

“Plasma atomized Ti-6Al-4 V (Grade 23 with oxygen content no more than 0.13 wt%, 15–45 µm) and spherical CP Ti (Grade 1 with oxygen content no more than 0.18 wt%, 38–63 µm) were blended using resonant acoustic mixing.”

Powder Technology

“Resonant acoustic mixing has been of particular interest for use in additive manufacturing since viscous, solids-loaded materials can be difficult to mix and inhomogeneity has adverse effects on print quality. In this study, we detail a method to iterate through different formulations and mix procedures and assess mixture quality.”

Materials & Design

“The 3YZ inks were made using solids loading in PEGDA ranging from 55 to 70 wt% (18–30 vol%, Table 2). The ink was mixed with spherical zirconia grinding beads (4mm diameter) in an acoustic mixer (LabRAM II, Resodyn Acoustic Mixers, Butte, MT) for 3h at 70 g-force to break up agglomerates and disperse the particles. The LabRAM II mixing time was determined by SEM images of the inks at different time points to ensure homogeneous dispersion... “

“…The blending process was carried out with a Resodyn LabRAM II
acoustic mixer operating for 1 h with 10 g’s of acceleration.”

Scientific Reports

“To produce AM material, equiatomic NiCoCr medium entropy alloy (MEA) powder which exhibited a diameter size range between 10–45 μm and Y2 O3 particles rated between 100–200 nm were acquired. A Resodyn LabRAM II ResonantAcoustic™ mixer was employed to coat the NiCoCr powder with one weight percent of nanoscale Y2O3...[the LabRAM II] quickly homogenized the powder, eventually coating the larger NiCoCr powder with a thin film of Y2 O3 after an hour of mixing in a polyurethane container...”

Proceedings of the Combustion Institute

“...20g batches of propellant were hand mixed in a 473 ml jar until
the AP was wetted. The mixture was then placed into a [Resodyn Acoustic Mixers LabRAM] resonant mixer. The HTPB binder propellant was mixed for 3 min at 80g for three repetitions with further hand mixing between cycles while the UV binder propellant was mixed in the Resodyn Acoustic Mixer for 2 min at 80g for 30s followed by a rest period of 30s...the techniques demonstrated in this paper could be used to create a wide range of complex grain structures that were not previously possible to manufacture.”

“New processing technologies are allowing researchers, industry and academia to probe new materials space not previously achievable. These technologies include additive manufacturing and Resonant Acoustic® Mixing (RAM), both of which have expanded in their use and application over the last 15–20 years.”

“The three reactive systems were formulated with an equivalent amount of dry powder Methocel using a Resodyn LabRAM mixer and same method as the dry powder mixtures that did not contain Methocel.”
