Frequent Asked Questions
What makes nScrypt machines stand out from the competition?
Our machines offer the highest precision in Micro-Dispensing technology. They give the user an
incredible amount of freedom to experiment with a wide range of materials. Our tool heads allow
the user to dispense inks and pastes, print with filament, mill material, and pick and place parts
all in one build, without tool changes.
How small can the machines print?
Our machines have printed lines with pastes and inks as small as 20 microns in width. The size
is dependent on the size of the pen tips from which the material dispenses. As a general rule,
the pen tip’s inner diameter should be at least ten times bigger than the particle size of the
material. However, the size also usually depends on the application the material is being used
for.
How do I choose which size pen tip use?
As a general rule, the pen tip’s inner diameter should be at least ten times bigger than the particle size of the material. However, the size usually depends on the application the material is being used for.
How big can the machines print?
It depends on the tool. The following is a table that shows the maximum print size:

What are tool heads?
Gizmos are our own modular tool heads that attach to the slots on our nScrypt machines. Each
one performs a different part of the Direct Digital Manufacturing process.
The SmartPump is our precision Micro Dispensing gizmo.
The nFD™ is our filament-dispensing 3D printing gizmo.
The nMill™ is our precision micro-milling gizmo.
The nPnP™ is our pick and place gizmo.
What are some applications that nScrypt tools could be used for?
Our machines are used for Direct Digital Manufacturing of electronics packaging structures with
functionally active circuits and electronics; printing adhesive dots and patterns, solder paste,
and filling vias; and building plastic and composite parts. Our bioprinter prints bio-materials,
including biopolymers and living cells.
How are print jobs performed so precisely?
Our machines include camera options that provide close-up images of the pen tips of our
tool heads, which allow the user to print within microns above a part’s surface. Our systems also
include a Keyence laser option that scans the part’s surface and adjusts the print according to
the variable height of the scanned surface.
What materials can print on the nScrypt machines?
The SmartPump can print any ink or paste up to 1,000,000 cP. The nFD™ can print any
filament with a standard 1.75 mm diameter and a melting point up to 400°C.
How fast can the machine make a 3D printed object?
We have demonstrated print speeds up to 1 meter /second. The speed of a print depends on
several factors: the size of the part, the material’s properties, and the level of detail. Our
machines allow the user to test and determine print speeds quickly with any material.
Can I print with multiple extruders?
The short answer is yes. Our machines have the option of including our largest tool plate, the
Penta-head, which can house five tool heads. The operator can mount five nFD™ tool heads to 3D
print with five materials. The operator can mount any combination of tool heads, such as
combining extrusion with Micro-Dispensing and milling.
What file formats work for print jobs?
For 3D printing with our nFD™ tool head, our software accepts gcode, which is generated by a
slicer program that takes STL files and converts them to gcode.
For Micro-Dispensing with our SmartPump tool head, our software uses our own proprietary
code that is outputted as a .txt file. We also provide a software tool that accepts DXF and SVG
drawing files and coverts them to the script required for printing.
Once the machine is plugged in, how long does it take to set it up and start printing?
Depending on the experience level, it should not take longer than an hour. This includes
preparing the substrate, mounting the tool heads, calibration, project setup, and material set up.
Once the machine is set up and the tool heads are not changing slots, projects can be
manufactured without redoing the set up procedure. For highly precise prints, however, we
recommend calibrating the tool heads daily.
Do nScrypt machines have UV curing?
Our machines have the option of including a UV lamp.
How are nScrypt machines able to print electronics?
The SmartPump can be used to dispense conductive paste while the nPnP (Pick and Place)
can pick, move, rotate, and place electronic components onto the printed circuit. Using other
tool heads or other materials in a SmartPump™, dielectric materials can be printed. For RF
applications, strategic areas can be smoothed with the nMill™.
What size bits can the nMill use?
The nMill can be equipped with any bit with a 1/8 inch shank.
What materials are compatible with nFD™?
Our nFD™ tool head is compatible with a wide range of materials. nScrypt prides itself on the
large material range for our gizmos and tools. Some of the materials include PEEK, PEKK,
ABS, PLA, Ultem, and a plethora of others.
How is the nozzle size determined for the print?
Selecting the right nozzle size is dependent upon the material and the size requirements of the print.
How to load materials to the SmartPump™?
When loading materials into the SmartPump™, the material is measured and poured into a
syringe. Next, air bubbles are purged from the material by spinning the syringe in a centrifuge.
Lastly, a coupler is attached to the syringe and is then mounted onto the SmartPump™’s valve
body. At this point, air pressure can be enabled to allow material flow.
