BEAM DELIVERY FiberWELD DH
Laser Mech’s FiberWELD DH is a high-power, laser wire, direct deposition head for processing macro-scale industrial and aerospace components. The head delivers multi-axis laser energy to a centre-fed process wire for total directional independence Engineered for high-duty cycle
production applications, FiberWeld DH features direct-cooled reflective optics, back-reflection protection and wire feed. In addition, FiberWeld DH’s easily accessible, protective cover glasses extend the life of internal optics. Primary applications for
FiberWELD DH include additive manufacturing, cladding and hybrid laser-arc welding.

Low GDD and high LIDT optics
Edmund Optics (EO) now internally manufactures short pulse optics with low group delay dispersion (GDD) and optics with high laser-induced damage threshold (LIDT) specifications out of EO Florida, formerly known as Quality Thin Films. Low GDD optics minimise chromatic
aberration and pulse spreading in ultrafast laser systems, resulting in higher peak powers, while high LIDT optics help reduce the likelihood of damage and system failure in high-power applications such as laser cutting, drilling and welding. EO Florida does not just design and coat
low GDD optics, it can now also provide the highly-sophisticated metrology required to verify their specifications. It uses white light interferometers and an in-house
CEM-E2 extruder
AIM3D, a manufacturer of multi-material 3D printers, has developed a generation of print heads for composite extrusion modelling (CEM), a process based on both fused deposition modelling and selective laser melting. The appeal of CEM lies in the use of multiple materials, cost savings and a reduction in build times through the use of pellets. The new CEM-E2 extruder is a multi-
material head that can print metal, plastic and ceramics. Its print heads are matched to different material groups: the ‘M’ (metals) version is for metal-filled materials (MIM pellets), the ‘P’ (plastics) version is for filled and unfilled plastics, while print head ‘C’ (ceramics) is for higher abrasion ceramic-filled materials (CIM pellets). The new print heads are characterised by exceptional accuracy of delivery. This enables
ultrafast laser to measure GDD, enabling the measurement of these challenging optics to verify their performance in real environments. Low GDD optics from EO Florida are measured before they are shipped, guaranteeing GDD specifications from 250 to 3,200nm within +-10fs2.

QUALITY CONTROL
SFM-AT200 with frequency excitation
Solukon has
equipped its SFM- AT200 automated de-powdering system with ultrasonic frequency excitation. Medical device manufacturers, in particular, will benefit from this feature, according to the firm.
The SFM-AT200 is Solukon’s entry-level
depowdering system. Its small footprint and easy operation make it the ideal unit for small and medium-sized metal parts. It is ideal for depowdering medical components with lattice structures. So far, the SFM-AT200 has used
Solukon’s Smart Powder Recuperation Technology – removing residual powder from complex metal parts by part rotation and controlled vibration in a safety- controlled atmosphere. Occasionally, however, powder residues can get stuck in particularly narrow internal channels or porous structures, as is often the case with medical components, despite rotation and vibration. To completely depowder these challenging geometries as well, Solukon has developed a highly-efficient ultrasonic excitation function. Electric frequency excitation in the ultrasonic range makes the powder ‘flowable’, allowing it to flow out of even the smallest channels in seconds. As a result, components can now be cleaned comfortably and reproducibly within a few minutes.

671 NIR2 Laser Wavelength Meter
Bristol Instruments has made an addition to its 671 Laser Wavelength Meter series. The 671 NIR2 system supports the characterisation of infrared lasers with the benefit of fibre-optic input. The 671 NIR2 Laser Wavelength Meter is
high surface quality and better mechanical properties of the produced component. Manufacturing rates of up to 220cm³/h with a 0.4mm nozzle are now possible.

ideal for scientists and engineers who need to know the exact wavelength of their CW lasers that operate from 1.0 to 2.6μm. It employs a Michelson interferometer-based design to measure laser wavelength to an accuracy as high as ± 0.0002nm. This new system includes the convenience of a pre-aligned fibre-optic input to ensure optimum alignment of the laser under test, resulting in uncompromised accuracy. In addition, with fibre optic input, the system can be placed in an out-of-the-way location, thereby conserving space.
