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 gizmos allow the user to dispense inks and pastes, print with filament, mill material and pick and place parts all in one project.

How small can the machines print?

Our machines have printed lines out of 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.

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 gizmos?

Gizmos are our own modular tools that attach to the slots on our nScrypt machines.  Each one has a different capability to help test DDM processes.
The SmartPump is our precision microdispensing gizmo.
The nFD™ is our filament dispensing 3D printing gizmo.
The nMill™ is our precision 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 printing adhesive dots and patterns, solder paste, plastic parts, composites, circuits, electronics, and bio-materials to include biopolymers and living cells.

How are jobs performed so precisely?

Our machines include cameras that provide close-up images on the tips of our gizmos that allow the user to print within microns above a surface.  In addition, our systems include a Keyence laser that scans the surface and will adjust 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 up to 400°C.

How fast can the machine make a 3D printed object?

We have demonstrated print speeds up to 500 mm/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 that is tested.

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 gizmos.  The operator can mount five nFD’s™ to perform 3D printing with five materials.  In addition, the operator can mount any combination of gizmos we provide.

What file formats work for print jobs?

For 3D printing with our nFD™, our program accepts gcode for its file format.  This is generated using a slicer program that takes STL files and converts them to gcode.
For microdispensing with our SmartPump, our program requires our own special code that is outputted as a .txt file.  We 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 gizmos, calibration, project setup and material set up.  Once the machine is set up and the gizmos are not changing slots, jobs can be performed without doing the entire set up procedure.  For highly precise prints, however, we recommend calibrating the gizmos 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 gizmos or other materials in a SmartPump™, dielectric materials can be printed.  For RF applications, smoothing can be done using the nMill™ on strategic areas.

What size bits can the nMill use?

The nMill can be equipped with any bit with a 1/8 inch shank.

What materials is compatible with nFD™?

Our nFD™ is compatible with a wide range of materials. nScrypt prides itself on how large the material range is 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 eliminated 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.
