■ Extrusion Tooling
■ Galvo Scanning Heads
Guill Tool & Engineering,
West Warwick, RI, has
introduced an extrusion
crosshead that uses microfi
ne adjustment screws for
precise concentricity adjustment.
The Micro Medical
provides precision of concentricity that
reaches 0.008 in. or fi ner per revolution. One
adjustment bolt controls 360° of adjustment.
Features include a patented cam-lock defl ector
for quick changeovers, with a residence time
of one minute at 0.5 lb/hr material fl ow, optimized
usage with extruders measuring ½ and ¾
in., and a max die ID of 0.250 in. In addition to
both vacuum and micro-air accessories, it is also
ideal for pressure and sleeving applications. Fluoropolymer
designs are available upon request.

■ Micro Drive
An extra- lowvoltage
micro drive
is available from
Siemens, St. Paul,
MN. The Simatic
micro drive consists
of the PDC (pro -
fi drive control) servo
drive in conjunction with a fl exible range
of motors and connecting cables from product
partners, along with the TM (technology
module) format with servo and stepper
drives in compact 20 mm width that can be
used in conjunction with distributed or open
controllers. Communication takes place over
PROFINET using PROFIsafe and PROFIdrive
profi les. A new safety integrated function,
SLT (Safely Limited Torque), limits
torque by monitoring motor current in running
operation.

Amada Weld Tech, Monrovia, CA, has released a range of galvo scan
heads for precision laser welding application. The galvo scan heads
feature advanced, intuitive software dedicated to welding and a confi gurable
pattern to adjust for part geometry and enhance weld performance.
An integrated safety shutter ensures a safe work environment
for operators. The robust solutions are designed to work with lasers up
to 3 kW and fi eld sizes up to 100 × 100 mm. They can be integrated
with a linear stage motion to weld at diff erent workpiece heights, or a wobble can be added to
linear motion for the accommodation of tolerances in fi t-up for seam welds.

■ 3D Printer
nano3Dprint, Burlingame, CA, has launched a submicron
printer for additive manufacturing. Capable of a 20 nm print resolution,
the D4200S off ers a nano-deposition mode that is capable
of printing between 20 and 250 μm, with printing positional
accuracy at <1 nm. The unit's print heads accommodate various
print materials, including gold, silver, copper, polymers, metallic
oxides, organic compounds, and photosensitive polymers. It includes
AFM capabilities for analysis, nanowriting, and patented
3D printing technology, enabling users to set foundational advancements
for complex biological structures.

■ Collaboration Tool
Authentise, Philadelphia, PA, has released a new tool designed
to deliver powerful digital thread capabilities, combining
communication and project management tools into a work
thread collaboration suite. Authentise Threads enables teams to
create, search, follow, and link shared work threads across engineering
teams and partners with real time structured communication, chat, and notifi cations. A
shared repository holds all key data, resources, goals, metrics. The tool enables teams to formally
track and manage workthread eff orts, insights, actions, decisions, and resolution, while also sharing
full history and traceability of work, discussions, issues, decisions, actions, and metrics.

■ Brushless Flat Motor
Portescap, West Chester, PA, has added a new brushless DC fl at slotted motor to its fl at motor
portfolio. The 45ECF features a performance optimized design that utilizes an outer rotor
confi guration with an overall diameter of 43.2 mm and a body
length of only 22.5mm. The motor features hall sensors to easily
control speed and torque and can be provided sensorless based on
application requirements. The motor can be used in combination
with existing gearbox designs to provide high output torque at required
operational speeds. With maximum continuous torque up to
91 mNm in a compact package, it is ideal for applications that demand
high performance in tight spaces. The high torque makes it
suitable for surgical robotics.

■ 3D Printing Material
Formlabs, Somerville, MA, has introduced a new material for medical applications for its
Form 3B, Form 3B+, and Form 3BL printers. Approved for human contact, BioMed durable
resin allows for durable biocompatible and impact-resistant
medical devices and instruments. The new formulation addresses
the need for a biocompatible material that can withstand
impact, rough handling, and pressure. Its impact-,
shatter- , and abrasion-resistant properties and excellent clarity
and surface fi nish make it ideal for patient-specifi c and customizable
surgical instruments, such as medical devices that
can be hit with a surgical mallet or shaken with a cutting saw.
