Valcrow explains his 3D design philosophy at Tested

If you're a regular viewer of Tested you may have noticed a familiar face popping up the past few months... our friend Jacky Wan, a.k.a. Valcrow. Jacky is a regular guest blogger on the Ultimaker site and has created some of our most popular 3D models.

Norm and Sean over at Tested are huge fans of Jacky's work and invited him to come over and talk to them a bit about modeling, printing, painting and all the other facets of the addictive 3D printing lifestyle. Jacky brought a selection of his favorite prints to show off to the guys, and in every video covers the design philosophy behind the model. Pay attention, you're about to learn from the master here!

Obi-Wan Kenobi's lightsaber

First up is a huge favorite of everyone here at Ultimaker: Obi-Wan Kenobi's lightsaber. It contains many of the hallmarks of Jacky's style of 3D design: snap-together models with smartly designed joints that need no external fasteners or adhesives, perfectly split up for ease of painting.

Mechwarrior mechs

Next up are Jacky's battlemech models from the Mechwarrior: Online game. He talks about the challenges involved in working with game 3D assets that were never intended to become physical, tangible objects. How do you turn such incomplete designs into models that your 3D printer can actually produce?

The Jenner model shown here is of particular interest, as it is the model known as Sarah's Jenner in the Mechwarrior world - created in honor of a young player who died of cancer.

Ducati 1199 superbike

The Ducati 1199 Superbike posed a similar challenge to the battlemechs. As the Ducati model Jacky started with was produced as a VFX model, there were many issues that made the motorcycle unprintable. He had to basically redo the entire model to create more than 40 separate printable parts.

Steampunk Iron Man hand

The following print should also be familiar to regulars of the Ultimaker site: the e-NABLE project creates 3D printed hand and arm prosthetics for those in need. This particular version of the e-NABLE Raptor hand was made even more impressive because Jacky redesigned it to look like Iron Man's hand, if Iron Man was a character in a steampunk universe. This version is still a work-in-progress and not quite usable as a prosthetic yet, but Jacky would love help from the community in getting it that far.

This version of the steampunk Iron Man hand is available on YouMagine:

3D printed airplane model

In the next video Jacky talks about his 3D printed plane model. Some of his most impressive design tips are detailed in this video. Take for example the two-part hull, which Jacky designed to be printed flat on the heated glass build plate so the ends perfectly fit together using a double dovetail joint. Or the wings, which are printed at a specific angle that may look unnatural, but lets all of the overhangs print at angles that are gentle enough that they do not need support anywhere.

Finishing and painting 3D models

And last, but not least, Jacky talks about general tips and tricks for finishing and painting his models. He talks about simple tools like his airbrush station or his Canada ball painting mask, and his preference to get the right the surface finish by using small layer heights and proper print direction, instead of sanding or epoxy coating.

We have a treat coming up for you in the next few weeks in regards to that plane model... stay tuned!

And in case you can't get enough of his work either, the most recent models from Jacky that we've featured are the amazing Vertical Axis Wind Turbine and the Fallout 4 Mini Nuke. And you can't miss out on his article about painting 3D printed models:
