From Want to NEED in an Instant

From the first time I saw the Cube 3D printer I was convinced that I NEEDED one.  Of course, the reality is that I WANTED one... a LOT!  :)

Now, for the first time, I TRULY NEED a Cube 3D Printer!

That change of status came about a week ago, today, on the second level of a parking garage in Washington, DC as I was headed to join some of the Youth Challenge cadets that I teach for the 3rd day of the  USA Science and Engineering Festival (USASEF).

The usual terminology is that one "suffers" a stroke.  But, in my case I "experienced" a stroke that resulted in weakness in my left side, some loss of control of my left hand and a new appreciation for God's incredible intervention in our lives for positive outcomes.

Two levels down in a virtually empty and unfamiliar parking garage, I had just pulled up to an elevator when the stroke hit.  The elevator turned out to be locked.  But, it had a large sign clearly identifying the elevator's location.  This allowed me to precisely let the 911operator know exactly where I was.  And, just as I dialed 911, a car pulled up.  It turned out that the wife in the car was a Physical Therapist for a hospital and took over the phone call as I sat down in my car as we waited for the medics, who miraculously arrived in minutes.  As the medics pulled me up and out via the steep garage ramp, she called my wife to tell her what was happening.

I certainly didn't know it at the time; but, God's hand was in the location of my stroke because the closest hospital was George Washington University Hospital which has an amazing stroke center and brilliant rehab therapists.

I am now home and doing very well with absolutely no cognitive affects and remarkable improvements in my ability to move my hand.   My hand and fingers are still weak, but, are improving by the minute.

This weakness is the very thing that changed my relationship with the Cube 3D printer from a WANT to a NEED!  I NEED some things to compensate for the control I've lost.  And, a primary example comes from the Cube itself.  My left hand does not have the strength, as yet, to hold the print plate while I apply the Cubestick glue!

It is the Cube, itself, that provides the solution.  I just needed to design a holder for the print plate that can be clamped to a table to solve the problem!

Print Table Holder for Single Handed Gluing

In just a few hours of printing, I can now apply the CubeStick perfectly!  And, this is just the beginning of creating tools to help me overcome any impediments that came from my stroke or help me in my therapeutic exercises.

I'm very thankful that my stroke was not more devastating.  I'm thankful that I was in the right place when the stroke occurred and that the right family pulled up next to me at precisely the right time,  But, I'm also thankful that I came home to a tool that can provide so much help to me as I recover so that my life can continue to be as normal as possible.

Little did I know, when I first saw the Cube 3D printer at 3D Systems 2+ years ago, just how important that wonderful 3D printer was going to be for me!  I appreciate the hard work of the Cubify team all the more and am thankful that the result of their hard work is making my life so much easier than it might be without it.

Sculpt Tutorial #7: Mashup - Unlocking the Power of Cubify Sculpt

OK, so we're getting things a little out of order here.  Tutorial #6 was suppose to go over the usefulness of changing the shapes of the primitives (Cube, Sphere, Cylinder & Cone).  But, I became so excited about extending that concept to creating NEW primitives that I just had to show you that first.  We'll get to #6 as soon as possible.  :)

First, a side topic that you may find interesting.

Before trying Cubify Sculpt, I tried any number of sculpting applications.  Each of them were decent.  And, among the best is Sculptress... IF you are a true artist!!!  I tried it again just to see if I'd learned something since trying Sculptris that had made it easier to learn Sculpt.  The answer is, "No!"

I was no better at Sculptris this time around.  It is DEFINITELY an artist's tool and not for me.  There is nothing wrong with the product.  I just get lost in it.

What that means...

It means that there is something fundamentally different about Cubify Sculpt that is making it easy for me to accomplish more than I have with any other sculpting program.

But, there is more!

I already understood that I was able to get more done and better with Cubify Sculpt.  But, then something dawned on me that blew the doors wide open.  And, that is that I do NOT have to create everything about an object from one single primitive.  I can save the basic primitives in multiple forms and bring them back into my working environment multiple times if needed.  And, THAT little realization boosted my ability to create with Sculpt exponentially!

It made it possible for me to create, in a reasonably short period of time, these Hippo models.  My granddaughter LOVES Hippos and I have been trying for YEARS to create a 3D Model of a Hippo that even remotely looked like one.  The proportions aren't perfect.  But, as you can see by this very short video that I made for her, they at least don't look like fat cows!  LOL!

The Breakthrough

The breakthrough for me was the realization that I do NOT have to create a form from a single primitive that is stretched and pushed into submission.  I can create PARTS as standalone pieces and then assemble those parts together as a MASHUP, or mixture of parts.

I could never, in a million years, have created the above hippos from a single shape.  But, by using different primitives for the body, head, ears and legs, the process was not only doable; but, relatively quick.

So, here is the process that I am talking about.... Tutorial #7, Mashup!

By the way, there is WAY more to cover when it comes to creating new primitives, like the Torus in this video.  I'm really excited to show you what that is all about in Tutorial #6... even if the order is a bit disconcerting!  :)

Cubify Sculpt and the SpaceNavigator

Good News!

The SpaceNavigator 3D Mouse device from 3DConnexion works well with Cubify Sculpt!!!

I had noticed that the Options Dialog had a tab for "SpaceBall Device".   Since I knew that the original SpaceBall had been discontinued, I asked Sculpt Support if that feature would work with the SpaceNavigator that seems to have replaced the original Spaceball.  They indicated that it would.

So, yesterday, I ordered the SpaceNavigator from B&H Photo and it arrived today!!!  That was a big surprise since I expected it no sooner than next Tuesday.  B&H Photo must have UPS trucks lined up at their loading dock because that was amazingly fast shipping from New York to Kensington, MD!''

I will include a short demonstration of the control that the SpaceNavigator provides in an upcoming tutorial.  It's going to take some practice to isolate just the motion I want without affecting other motions.  But, I can already see that it is a great investment and works quite well.  The speed with which it works can easily be controlled either from Sculpt or in the SpaceNavigator control form.

Control Includes...

• Pan Up and Down
• Pan Left and Right
• Zoom In and Out
• Spin
• Tilt
• Roll

Cubify Sculpt Tutorial #3: The Beauty of Emboss Area and Texture Maps

I mentioned Emboss Area and Text Maps in a previous post.  I expect to explore these two features in many more tutorials.  They are SO powerful and make adding ornamentation SO easy that it truly makes designing in Sculpt child's play!

When I first heard that the president of 3D Systems was committed to the democratization of 3D printing and design, it was difficult to know if it was a sales slogan or a fundamental core value.  With the introduction of Cubify Sculpt, I now know that it is definitely a fundamental core value and a true commitment.  Cubify Sculpt has the potential to bring 3D design to just about every age group and just about every level of technical competence.

As an educator that taught from 1st grade to high school students, I always hoped that someone would create a product that could be used at the elementary level as well as the higher grades.  While younger students might not be able to create great works of 3D art with Cubify Sculpt, I am convinced that the feature set WILL allow them to successful create nice objects to be printed on a 3D printer.

Cubify Sculpt has the potential to be a major tool for school projects in STEM, Art, Geography and other disciplines.  In this video we show how a simple 2D STENCIL and TOPOGRAPHIC MAP are easily turned into Texture Maps to create reasonably complex 3D features. 

As you can see, a simple paint program can be used to create a tool to be used with EMBOSS AREA to complement any shape.  The fact that Texture Maps WRAP make them particularly powerful.

Cubify Sculpt has exceeded my expectations in a HUGE way.

Cubify Sculpt Tutorial #2 - Setup and Potter's Wheel Simulation

I'm simply amazed that I have been able to actually complete some demonstration projects so quickly in Cubify Sculpt.  I can assure you that this would not have been possible in any of the other sculpting applications I've tried to learn in the past.

One of the first upgrade features that I asked for when I first opened Cubify Sculpt was the ability to manipulate the clay in the fashion of a Potter's Wheel.  Well, it turns out that we can do just that using some hot keys or, I hope, by using a Spaceball type of device.  I've been told that the SpaceNavigator device can be used to spin objects with one hand as the other is used to sculpt.  But, we don't have to wait until a SpaceNavigator arrives to test the concept.

It turns out that the ARROW KEYS can be used to spin the object a specified number of degrees and by holding down the ARROW KEY we can do so continuously.

Here is a video that shows the concept!

The image used for the video preview is the SpaceNavigator.  I have ordered one and should have it by next week.  I was under $100 and I am looking forward to seeing how well it works!

The combination of being able to start with an STL, like the chalice, which is VERY easy to create in a CAD program; but, slow to create in a sculpting application and the having the ability to quickly add features while spinning the piece is a VERY powerful capability.  The ARROWS and other Hot-Keys are good things to explore.

I love it!

Cubify Sculpt - Emboss/Texture Maps: A Power Tool Combination

One of the problems I've had with previous sculpting tools I've tried is just how long it takes to make something useful in an educational setting.  If all we had were Push/Pull style tools, that would be true of Cubify Sculpt.  But, it's worth taking a look at the EMBOSS AREA tool and particularly the CUSTOM (with TEXTURE MAPS) option.

In fact, a good number are included with the Cubify Sculpt install, in the PATTERNS directory under the directory where Cubify Sculpt is installed.

Any black & white bitmap image having various levels of gray can be used with the Emboss Area tool.  The lighter the area, the higher the embossing action.  White areas will emboss the highest and black will not be raised at all.  The shades in between will be raised higher as the color moves to white and lower as the color moves toward black.

EDUCATIONAL APPLICATIONS

My main reason for exploring this feature so early is that a number of people have asked me about using the Cube / 3D Printing in an elementary school setting where the time allotted to teaching a 3D creation is limited.  At first, I was skeptical that Cubify Sculpt would meet that requirement,

But, the more I have explored the concepts of "TEMPLATES" (pre-designed basic shapes to be modified) and "Texture Maps" (pre-designed embossing stamps), the more I'm convinced that Sculpt would allow teachers to integrate 3D printing in just about any classroom.

SCIENCE EXAMPLE

From my high school days, one of my most consistent hobbies has been protozoology.  Some people watch birds, I watch protozoa.  In the late 1970's I taught Junior High Science and so it was natural for me to begin the exploration into how EMBOSS AREA could be used to provide a jumpstart for a student to design their own protozoa models.  For a future article, I will create a tutorial showing how the Texture Map was created and used.  But, for now here are images that show the Texture Map on the left and the final model on the right.

Amoeba Texture Map (Bitmap)

The above image was created in a 3D paint program.  Any, paint program can be used.  The important thing is that lighter areas will result in higher embossing and the black areas will not emboss at all.

Here is the above picture side-by-side with the resulting 3D object.

3D Amoeba Created From Texture Map

Here is another view that demonstrates the embossing a bit better. 

Amoeba Model at an Angle

The bumps in the surface were added after the emboss created the basic shape.  The embossing was done on the surface of a cube and then the cube was cut away using the REMOVE CLAY WITH BOX tool.  While the Texture Map was used like a stamp on the surface of the cube, there was still plenty of design modifications, such as lumps, bumps and indentations to the surface that the student could add.  Older students could have even created the Texture Map itself.  In fact, the Texture Map could even be created using a microscope image of a real creature!  Just convert the color image to black & white.

Finished Amoeba

The beauty in the fact that we can use gray scale images to create 3D features is that the images can be created in a variety of ways, including mathematically   Again, this isn't great art.  But, it DOES demonstrate the usefulness of Cubify Sculpt in a STEM (Science, Technology, Engineering & Math) program. 

The Care and Feeding of the Cube 3D Printer (Video)

I've been wanting to create some better videos about the Cube 3D printer, itself.  This is the first attempt in that direction.

I have received a number of emails from users that have described this or that issue they've had with their Cube printer.  Some have had clogged heads and others have asked about the using the CubeStick glue to best effect.  This video covers the following topics...

Setting the Head Gap

Nothing will clog a 3D printer faster than when the print jet is hitting the print bed.  Yet, we need a very small gap to ensure that the first layer of filament is properly laid down on the print bed.  A TWO STEP process for setting the gap is demonstrated along with the paper I've found that works the best for me.

Applying CubeStick

One of the most challenging thing for me, when going to the new 2nd Generation Cube from the 1st Generation Cube was the different behaviors of the two different glues.  The first generation Cube used a heat activated glue and, frankly, was a LOT easier to use both before, during and after the print job.

I found that I was having a LOT of trouble getting parts to stick immediately after I'd cleaned the print bed.  And, I didn't realize that by trying to solve the problem by applying thicker coats of glue only resulted in transferring glue to the little rubber cap over the print jet... essentially gluing the flowing filament to the cap and not the bed.

Finding the proper gap helped.  But, finding a more reliable system for applying the CubeStick was the real solution.

A Tip When Changing Cartridges

For a long time, I created some problems for myself because I did not understand the correct timing for pulling on the filament when removing it to change cartridges.  When the Cube team explained the steps of the process that the Cube takes when removing filament, I came up with a visual clue for myself that allowed me to more easily go with the flow when removing filament.  The result is no more instances of broken filament inside the print jet!

The Correct Way to Insert the Cartridge

While teaching a 3D printing class at Freestate Challenge Academy, we had two different instances where the little metal contacts in the cartridge slot were broken as the student loaded cartridges.  From this experience, we learned two things.  (1) The correct process for inserting the cartridge and (2) how to solder in replacement contacts.  We will show the latter later.  But, for now, this video demonstrates the SAFE way to insert new cartridges to avoid the potential for breaking the contacts.

The Video...

This is the first of the videos that I hope to bring you regarding the Cube 3D Printer, itself.  As will be clear, I do not write a script.  So, you will hear some obvious errors... such as when I talk about lowering the head when I really mean the bed.  But, I'm trusting that the information is useful enough that you will forgive my slips here and there.  I have to do these videos and tutorials in the limited time that I have to do them.  So, perfection is NOT an option.  :)

I have made the difficult decision to use the YouTube "Monetize" option to help offset the costs of the investment required to bring a higher quality of videos to you.  I know that it's annoying. But, hopefully you will find some of the products and services advertised useful enough to click on at least some the ads.

That investment, by the way, included a new Panasonic HC-X920 video camera and new LED 100WA-56 / LED 200WA-56 lights.  I mention this because these products have only recently been introduced and some of my fellow members of the DPReview forums have expressed an interest in seeing how well they perform. 

If you have the bandwidth, try viewing the video in HD 1080p, to see why I feel that investment was well worth it.  I love this combination!

Well... with that said... here is my first 2nd Generation Cube video!

Invent Intro #04 - Circles (Extrusion Boss & Cut)

Extrusion is one of the most used commands in any CAD program.  And, Cubify Invent is no exception.  It is THE primary way that we turn a 2D sketch into a 3D object. 

There are two types of EXTRUDE that can be used in Cubify Invent.  They are EXTRUDE (Boss) and EXTRUDE (Cut).

EXTRUDE (BOSS)

Essentially, EXTRUDE (Boss) ADDS layers of material in the shape of the 2D sketch to form a 3D object with features defined by the 2D sketch.  I don't think that it's a stretch to call EXTRUDE (Boss) the most used 2D to 3D option.

Using EXTRUDE (Boss), a 2D circle becomes a 3D Cylinder having height as well as a circumference.  A 2D square becomes a 3D box or cube when EXTRUDE (Boss) is applied.

EXTRUDE (CUT)

EXTRUDE (Cut) doesn't ADD material.  It REMOVES material, if any exists.  This is most often used to create cut-outs and holes in already existing 3D objects.  While not used as often as its boss counterpart, it is still an often used option and may well be second of all the 3D options in frequency of use.

Using the selected 2D sketch, it acts as a cutting die, removing the exact shape of the original 2D sketch from whatever 3D object is crosses.  It can cut partially through an object or all the way through as the user determines.

Here is a video that demonstrates these powerful Cubify Invent commands at work creating a useful part that has bolt holes and a ledge that is counter-sunk into the part using EXTRUDE (Cut).

For those exploring Moment of Inspiration, here is how a similar part might be created using only EXTRUDE (boss) with MOI's Boolean Union and Difference Tools.  It's interesting how different applications accomplish the same task by going down two different paths. 

In a follow-up tutorial, we explore all the 2D and 3D BOOLEAN FUNCTIONS available in Moment of Inspiration.

Cubify Invent - Tutorial #4: Planar Surfaces and Tangent Planes

One of the problems that we face when creating tutorials as we learn a product is that we can miss some things resulting in misleading information.  I'm guilty of doing just that.

I had previous thought that we were limited to creating our 2D sketches on planes.  Happily, that turns out not to be the case.  We can also create 2D sketches on any flat surface of a 3D object.  These flat surfaces are called PLANAR SURFACES.

In this tutorial we continue exploring the surfaces on which we can sketch by looking at planar surfaces and TANGENT PLANES.  A tangent plane is one that is created tangent to the surface of a curved surface.  Typically, this would be the wall of a cylinder.

As you may have seen in the video, once we select a plane, planar surface or tangent plane on which to sketch, we can begin sketching beyond the visible boundaries that we see,  For instance, we might chose a very tiny planar surface.  Yet, we can draw well outside the boundaries of that selected planar surface.  And, the same is true of a tangent plane.  We are not limited to simply drawing within the limits of the curved surface with which that surface was created.

The more I work with Cubify Invent, the more I see its potential.  I'm beginning to see that once the learning curve has been put behind us, this is not only going to be a powerful tool; but, an easy and quick tool.  That is a good feeling to have to anyone interested in 3D printing moving into the mainstream.  Nice.

Shaping the Filament Tip for Loading

It is relatively important to shape the tip of the filament correctly before loading in any 3D printer.  The filament for the Cube is no exception.  Mike asked how I do this.  So, I thought I would mention several ways one can shape the tip correctly.

Since I'd had a 3D printer before the Cube, I'd already found ways to shape the end of filament using several different tools.

Flush Cutters

A micro flush cutter is a small cutting tool with cutting surface that is flat on one side.  This makes for a very clean cut.  Rio, a supplier of jewelry tools and supplies sells many varieties.

Micro Flush Cutter

 

Right out of college, my daughter set up a well equipped jewelry studio in our home.  It's still here.  As it became clear that shaping the tip of filament was important, I had a lot of tool choices close at hand.  Flush cutters will work.  But, it takes several cuts at different angles.

Nail Emery Board

The least expensive option is a simple emery board normally used to shape nails.

Emery Board

ABS filament is relatively soft and shapes very well.   For under $2.00 you usually can buy a set of boards with several different grits.

Dremel Sanding Wheel

Few tools are as versatile as a Dremel rotary tool.  This is my tool of choice in shaping the end of the filament before loading into either of my 3D printers.

Dremel Rotary Tool with Grinding Stone

The grinding stone attachment makes short work of shaping ABS plastic.. But, a light touch is a must.  Otherwise, it will melt the plastic.  Light touches as you go around the tip tip on all sides does the job very, very well.  Sanding wheels would also work well.

Obviously, these aren't the only ways to get the job done.  But, they represent 3 different approaches that I know work.

A ZBrush Expert Tests the Cube

One of the smartest things I've ever done in my life was to use my nephew, Peyton Duncan, in the early 1980's to test our video games for Astrocade's Bally Professional Arcade.  Not only was he terrific at finding issues with the games; but, he was also terrific at suggesting game play improvements.

But, it has also paid off for him, leading him to become an accomplished digital artist and game designer.  He is now an art director with Electronic Arts Sports.  He is an incredible artist and photographer.

One of the 3D modeling products that he has used, over the years, is ZBrush.  Two events provided an opportunity for him to test the latest release of ZBrush with the Cube 3D Printer. Last week, to test the new Dynamesh technology, Peyton created this high poly model in just 4 hours.  And, then he came to visit his family in nearby Virginia, giving him access to my Cube 3D printer.

Peyton Duncan - Old Man

According to Peyton, ZBrush with Dynamesh is amazing, allowing him to go way beyond the point where the mesh would become a mess in other applications.  I'm no great 3D artist so I don't even know enough to comment on it.  But, knowing his experience, I'm going to take his word for it.

For me, the fun part was having the privilege of being able to loan Peyton my Cube while he and his family are visiting his parents.  This gave him the opportunity to print his "Old Man" on the Cube.

Here is the result.

Cube Print - Old Man 01

Cube Print - Old Man 02

Cube Print - Old Man 03

The bust is 4.5" tall and took 24 hours to print.  It did require support materials.  The great news is that Peyton is very impressed by the quality of the print, given the fact that "Old Man" was not designed to be printed.  It was designed to push the capabilities of Dynamesh,  So, the surface being sent to the Cube is incredibly detailed. 

What was amazing to me, once I had a chance to see it, is that Peyton had chosen to set up the Cube printer in an area that undergoes big swings in temperature.  There was some bottom warping, which one would expect from such temperature swings.  But, over all, the filament binding was very nice in spite of the temperature swings over the 24 hour print cycle.

Obviously, the children were fascinated by the printing process and went to check on it dozens of times.  Peyton was highly impressed that the Cube could go for 24 hours while maintaining precise alignment even in the face of the children shaking the table on which it sat.

I plan to reprint "Old Man" in my studio where I can control the temperature more precisely... and, without the table shaking!  In the meantime, count Peyton in as a Cube fan.

Note:  "Old Man" is a work in progress.  When he gets back home he will finish it and send me a better STL file to print.  So, look for an update in the near future.
