Casting with Resin Masters

3dwax
Form labs sent me an email. I am on their mailing list. It provided a link to a guide for casting resin-based models using the Lost Wax Casting (LWC) process. I saved the guide to this website and have a link HERE => Recommended Burnout Process and Casting Guide . Download and look. My methods follow this guide closely. I haven't done anything c...

Put It To The Torch

DSCN0052
This is probably NOT a fair test of how castable resin performs inside an investment cavity. (mold) I just wanted to see what happens to this material when I put a torch to it. This was done out in the open atmosphere with probably a 1000 degree F heat from the torch. Lots of atmospheric oxygen freely available. Conditions inside investment inside ...

First Sliver Cast

First Sliver Cast ends in failure! Excessive ash residue in mold cavity seems to be the issue. Complete report posted here:  http://dimensionalart.org/art/index.php/component/content/article/10-lost-wax/61-3d-printing-for-lwc The WD7 printer produces excellent models , but the casting resin or casting technique needs a lot more time and effort...

Got the Timing!

DSCN0037
Yeah, boy! This looks like I now have the print timing for the 35um layers. This part looks excellent. I washed it in water before I took the picture so there are a few drops visible in the photo. I had to increase the diameter of the supports as well. So then I could use fewer of them. I also raised the slant angle of the part from 15 degrees to 2...

Gray-Scale Masking

There is a process of light equalizing that can be used within Creation Workshop 3D software and DLP printing. Probably other printing as well. It is called gray-scale masking. There may be a number of ways this can be used with DLP type printers. The one I viewed required measuring light levels at various points on the print screen with photo-resi...

Fat Print

A very fat
​Making castable parts with the D7 printer. But I have to make up my own set of "rules" on resin exposure. I am not there yet, making useable parts. The very first try I under exposed the resin. I had the very thin base that stuck to the build plate and a very thin version of the Item itself was just floating in the resin. I had to start some where...

Be a Sport

I suppose life can never be easy. Some parts are. But then there are those parts that always must be done the hard way. This hard one is me trying to find the proper exposure values for the UV resin I am using for 3D printing. No standards have been established for exposure value. It's like buying film (remember those days) for your camera with no ...

All Gone

DSC08103
The 250 ML of Wanhao 3D printing resin (white) didn't go too far. It is the amount included with a new printer to get the operator started in printing. So, I figured it was a good material with which to start. And use-up in a hurry… :) It is the type of resin that must be cleaned up with alcohol. Even thinned greatly it still leaves a slightly tack...

Always Use Caution

The testing is over. I have determined the Wanhao Duplicator 7 (WD7) is a perfectly safe and adequate 3D printer suitable for Lost Wax Casting (LWC) jewelry master model creation. I made a good choice for this intended purpose. This isn't a discovery, but a verification of suitability. However, the WD7 and any resin printer, in my opinion, is not a...

Rooked by the Rhino

Not cheated at all. The Wanhao D7 rhino made this. With a little help from me. This "rook" is sort of the default challenge piece for resin printers. Kind of like the "Benchy" tug boat is for FDM. Benchy can be printed with DLP if I desired. With his rook, all the sections are solid. No hollow infill pattern unless the designer builds it intro the ...

A New Cast

DSC08087
This is the first jewelry piece I have made with the WD7 printer. I think the inside support is probably not required with DLP printing in a round shape like this ring. I have a lot of learning to do with this new process. I think this ring should have been printed flat with support around the edge. It would also print a lot faster. This ring is no...

Thoughts on Watts

I just published an article on the construction of a UV curing box for use with my WD7 resin 3D printer. My first step in the design of this box was deciding on how I was going to produce the UV radiation. I also needed to know exactly the frequency required for the curing of the resins I would be using.  The UV spectrum is quite wide and divi...

Wanhao D7 Rhino Gets Wet Feet

I have posted 21 pictures of the set-up of my new Wanhao Duplicator 7 3D printer in the article portion of this web site. So, then I wanted to see if I could get it operating.  I have several copies of Creative Workshop software before it went commercial. I cobbled up a box-in-sphere trinket as my first victim, err... subject. I am not ready f...

Sneak Peek

Too soon to report anything about the Wanhao D7 1.5. It just got off the boat from China and, well... the DHL delivery truck. Here it is setting on my floor and parts spread out everywhere. I have a big task figuring this machine out and doing the set-up. More to come later. probably much later... Ha!​

The Story of the Tools

The intention of this website is to promote creative use of 3D printing. The printer machines are the tools, the hardware needed to make something. The software used to create the model is also a tool. The mission of RD3DPDS is to show the practical use of 3D printing.  My thoughts are that 3D printing is far more than operating the machine. T...

Second Sniff

I discovered why the resin I was sent for use in my Wanhao printer didn't knock my socks off. The product is a water soluble resin. It can be cleaned with soap and water. Friendly to people and the environment.  I had no idea at first. It doesn't say that on the bottle. I was looking for a cast-able burn-out resin, as my intent for the printer...

First Sniff

My D7 must be on its way from China. I received my first liter of resin from the distributer in Florida. The resin is available in USA. The printer is available in or from both the USA and China. I ordered from China as it included the new control computer as part of a special sale package. I can wait for the slow boat. I was and am concerned about...

Impressions on Critical Design

Currently, my impression is the FormLabs Form 2 SLI, Stereo Lithographic printer is among the most professionally presented high definition 3D printer on the market. It's pricing ($3.5K) is not extreme for any business that may need one and is approachable for a prosumer hobbyist with adequately deep pockets. Notice I didn't say it was the BEST 3D ...

CreationW3D

I am so disappointed that someone would pull a public domain software out of reach of the public domain access that created it. To me it is the same as taking the song "Happy Birthday" and simply putting a copyright on it.  Perhaps it is the only way the software could continue to improve or exist. Financial support was probably non existent a...

New 3D Printer

A learning process awaits me in the new year. I ordered a 3D printer that uses a process with which I have no experience. That's part of the enjoyment for me. A new learning experience. It prints using ultraviolet (UV) light to harden resin. It's done in layers like my previous printers. But is not an extrusion process. The UV method produces much ...
