the right prototyping process for the job top
Henning Product Development has a vast array of in-house and trusted suppliers to select the right prototyping process for your needs.
Prototypes can be for form validation, engineering
validation, installation in a working environment, a
pretty thing for a trade show, or all of the above.
What you want the prototype to do is a critical consideration
in which process you should use without spending too
much money for features you don't need.
Henning Product Development can help you select the
right prototype process for its intended use. We can
even build an entire assembly to meet your goals.
With Henning Prototypes, we make parts where gears
really work, vessels actually hold water and latches
snap the way they are supposed to. And they can be made
to stay that way day after day.
Go ahead and make a snap-fit assembly. Use bayonets,
threads of any description and thin tensioning sections.
You can make tubes that hold water or any other liquid
– even under pressure. Say you have an idea for
a new type of hose nozzle complete with acme screw that
mixes different spray patterns. We can build it for
you. Plus you'll have the parts to show your customers
and your tooling vendors! Send us your parts, tell us
what's important and we'll work to make it right
We offer prototypes in real ABS using
our FDM process, which is ideal for assemblies with
snaps and other parts that will ultimately be manufactured
in ABS, polycarbonate, nylon or other thermoplastics.
Our PolyJet prototypes are finer resolution allowing impeccable
detail for show-quality parts. Flexible prototypes are available using our
PolyJet prototypes for single parts and Urethane Cast
prototypes for larger quantities and more realistic
silicone-type parts. Metal prototypes allow you to get
cast and CNC machined metal prototypes of your part.
Wall thicknesses should be at least
0.020 inches thick and ideally 0.060 or more for a more
robust part. Any area that is less than 0.020 inches
may not work as intended. Be mindful of grooves and
other surface details that may reduce your wall thicknesses.
These parts may not print properly at the grove and
may actually end up as two separate parts. This is especially
true of FDM parts. If you do need fine detail, select
a higher-resolution prototype process such as PolyJet.
Threads should be made with our PolyJet or CNC process. We have made threads with very fine pitch. For PolyJet parts, the threads need to be modeled, which can be difficult. If you need help with threads, we can do that for you, just mention it in your request. CNC parts need drawings showing the threaded areas. Part resolution for ABS prototypes (FDM)
is 0.010 to 0.013 inches, which means that fine and
close-tolerance threads loose some of their fidelity
and may bind when assembled. Choose the extreme ends
of thread tolerances for FDM prototypes or select a
higher resolution prototype to ensure your model threads
Part resolution for PolyJet parts is about 0.0006 inches, which means that fine
and close-tolerance threads will hold their shape better. We have found that 0.010 thread tolerance is easily assembled with fine-pitched threads (around 40 tpi). Tighter tolerances to 0.005 or even 0.001 will work, but may require more post-processing to engage.
For 3D Printing, all threads must be defined as solids. Cosmetic threads
will not print.
Large solids and space-claim parts can
be made "sparse" for substantial savings.
If you just want to explore exterior designs before
full internal engineering, select "Sparse"
when submitting your part. These parts are made with
a 0.060-inch wall and a fine lattice on the inside to
help the part keep it's shape.
File types we use for prototyping
are STL. CNC parts require STP or IGS files. We can
accept other formats such as SLD, NEU, OBJ and PRT files
as well. For STL files, review the resulting file in
your software program to ensure you are satisfied with
the shape and resolution.
File resolution. It's best to reduce
your cord height and angle control to zero or the minimum
allowed by your software.
