Great Results – Switched from B9 Yellow Resin to B9 Emerald Resin






B9 Emerald Resin Use in Jewelry

Hello, I am Nicolas, the founder of Vivalatina Jewelry Workshop (the english version of my French main site) and I use B9 resin to 3D print the masters of my jewelry creations.

A while ago I published a post here about the use of B9 Yellow resin in jewelry. In mid 2017, I switched from B9 Yellow to B9 Emerald resin for my jewelry prints.

The reason, it is a bit cheaper so I wanted to test it.

Also, I had some trouble taking pictures of my yellow 3D printed parts. The tone and transparency of the B9 Yellow resin gave me trouble showing the details of my prints to clients when I sent them photos.

So after some months of use, and after being very satisfied with the B9 Emerald I decided to explain why.

What did not change:

There is no difference between the B9 Yellow and B9 Emerald in the incineration process. Both resins do well in the oven, burning well with no ash. For the parts I burn I have noticed no difference in use or result.

The curing time is also the same.

What did change: 

The pigmentation of the B9 Emerald is much more pronounced, so the details of 3D printed parts are much more visible on pictures and screens than the yellow resin printed parts.

The suspension of pigment in the resin is better for the B9 Emerald than the B9 Yellow, I have no idea why. Simply, the pigments are resting much longer in suspension with the emerald than with the yellow resin.

The life span/durability of the liquid B9 Emerald in the bottle is incredibly better than the B9 Yellow. I can leave my B9 Emerald for months in a darkened bottle with no visible quality degradation while I could not do so with the B9 Yellow resin.

There is no irritating smell with the B9 Emerald while the B9 Yellow had an unpleasant odor, which is important if you, like me, have your 3D printer close to your desk.

Customer Success Story – B9 Yellow Resin

How I use B9 Yellow Resin for my jewelry business – Nicolas Tranchant

I am Nicolas and I run a jewelry business online (vivalatina) that provides original design and on demand jewelry creations.  As most of my designs are pretty complex, I need a 3D printer to make those designs on demand as I sometimes can have failures on printing or while casting the parts in metal.  For this I used the 1200 Projet from 3DSystems at the beginning but the resin costs and lack of support (I was talking to sales people and not technical guys in case of trouble) led me to another model of 3d printer.

As I had trouble with the 3DSystems resins that could not be burnt sufficiently for a good casting process and was so expensive, I turned myself to the B9 Yellow Resin that a friend of mine had tested with success on his own 3D printer.  As I had great results, I now use the B9 Yellow Resin for my prints.

My core business is signet rings, and the whole collection is made with this B9 Yellow resin, but I know others could work also (the Red and Emerald B9 resins).

Here are a few examples of complex signet rings made from the B9 resin:
The 3D design:

and the 3D prints with the B9 Yellow:

The B9 Yellow Resin is difficult to photograph as the details are difficult to see, but the resolution of the details is perfect.

I have also made this massive gold and silver ring with the B9 Yellow:

It is made of 3 parts, each one cast on its own and then welded together. Here is one of these parts made from B9 Yellow.

This other ring, a lion’s head, is made from B9 yellow and then cast in silver:


The main characteristics of the B9 Yellow Resin are:
1. Very hard to photograph
2. The pigment stays mixed with the resin for a while when the resin is not used, so if you do not use your 3d printer for 2 or 3 days there is no trouble.
3. The pigments and resin mix very well when you need to mix it
4. It can be cleaned very easily with standard alcohol.
5. The cured resin is not damaged by the alcohol when you forget your printed parts in the alcohol recipient (which happens to me quite often)
6. It cured pretty quickly under UV for 2/3 hours and it’s done.

Introducing the New B9 Core Printers

We are happy to introduce two new printers from B9, the B9 Core 530 and the B9 Core 550.  If you are looking for an easy to use, professional grade 3D printer with outstanding speed, quality and value, the Core printers are worth considering.  Both printers use industrial HD LED light sources and can print at speeds of up to 100+mm per hour, four times faster than the industry average.  This means you could print hundreds of small precise models in 8 to 10 hours!

Integrated Touchscreen, Improved Vat, Auto Calibration

These new printers have an integrated touchscreen with a USB slot so you no longer need to have a laptop connected to the printer while printing.  Just transfer your files to a USB drive, plug it directly into the Core, select your settings and hit print.

Another improvement is the new bigger, more durable resin vat that is designed to last for hundreds of prints.  The wiper technology from the early B9 printer has been replaced with a more robust option in the Core Series.  So if you are printing frequently and have been replacing or recoating your vats weekly or monthly, the Core Series will save you time and money.  The printer is
also auto calibrating and contains a built in fume and odor filtration system, making it ideal for office settings.

B9 Core 530 vs. B9 Core 550

The main differences between the two models are the build size and resolution.  The B9 Core 530 has a resolution of 30 μ and a build size of 57.6 x 32.4 x 127 mm, while the B9 Core 550 has a resolution of up to 50 μ and has a slightly bigger build volume of 96 x 54 x 127 mm. The speed is also different in the two printer models.  The B9 Core 530 has an average build speed of 20-30 minutes per inch for the full envelope, making it ideal for custom production. Due to the larger build size of the B9 Core 550 (ideal for larger-scale models), its speeds range between 40-60 minutes per inch for the full envelope.

If you think the B9 Core Series would save you time and money in your jewelry business or with other detailed, high speed production, please feel free to contact Redresins for more information.


B9 Resins and Jewelry – When fine details and casting are critical

Jewelry Industry

In the jewelry industry, fine details and a clean cast are critical.  Many jewelers have been reluctant to switch from wax based models to 3D printed resin models.  This is because the casting process either had to be specifically tuned and lengthened for the resin or the burnout wasn’t providing needed results.  And other jewelers have been paying higher prices for printers and resins in search of outstanding pieces.  It seems the hunt for this perfect combination in resins has ended.  B9Creations seems to have cracked the code.

B9Creations Casting Resin

Earlier this year, B9Creations launched two new casting resins designed specifically for the jewelry industry.  B9 was confident they had found the balance with the new resins based on much research and development and feedback from both jewelers and casters.

We wanted to make sure the new resins could deliver so we contacted Micron3d here in Barcelona, Spain.  After casting the sample prints below and printing designs of their own, Micron3d confirms that they are getting great results with both the B9 Emerald and B9 Yellow resins.  The resins are working well on both the B9Creator and the Solus3D printers.

If you are looking for outstanding results from a casting resin, look no further than Redresins.

The sample prints below were made on the B9Creator and were cast using a standard burn cycle.  Photo credits: Micron3d

3D Printers for Jewelry – B9Creator vs. Solidscape

The B9Creator v1.2 HD 3D printer prints 4 times faster and is at least 1/4 of the cost of the Solidscape printer!

Cost of Printing

Solidscape printers have a reputation of being expensive to operate and maintain.  On the other hand, the B9Creator has very low operating and maintenance costs and replacement parts can be purchased online and installed easily.

In some instances the maintenance cost on the Solidscape = the cost of a new B9Creator.  Some jewelers have taken the money they would have spent on their Solidscape’s annual maintenance and bought a new B9Creator!

Speed of Printing

In the time it takes to do one print run on the Solidscape, you can do 3 to 4 print runs on the B9Creator!

Jeweler printed the same set of rings on:  

The Solidscape – 38 hours

The B9Creator – 4 hours

The jeweler could not notice a difference in the detail or surface area between the two prints and the CEO said, “I’m just the CEO, not a jeweler, but I’m pretty sure 4 hours is better than 38.”

Durability of Prints

The prints from the B9Creator are more durable than the wax prints from the Solidscape printer so there is no need for delicate handling and you can relax when handing the print over to your customer.

The B9Creator and Solidscape can be used in conjunction.  One customer uses the B9Creator to quickly and affordably print out customer proofs and reserves the more expensive Solidscape prints for the final design.

Overall Value

If you need to save time and money with your custom jewelry business, the B9Creator will be a valuable addition to your new or existing line up of 3D printers.  Who doesn’t want a 3D printer that is 4 times faster and 1/4 of the cost?


New Colors – Durable Vorex resin for engineering

As you can see in the image above, MadeSolid Vorex resin is going head to head against the competition and the results are impressive.

The toughness of MadeSolid’s Vorex resin is calculated by combining Tensile Stress and Elongation.  Tensile Stress measures how much force is needed to break a 3D print by pulling it apart and Elongation measures how long the material stretches before it deforms.  By multiplying these two together, you get toughness or the total amount of energy needed to break the 3D printed material. The higher the number, the tougher the resin.

So what does this mean?

In the past, the most common material for tough 3D prints was ABS.  However, there are limits to FDM 3D printing capabilities when it comes to detail.  Now universities, engineers, dentists and anyone else looking for a 3D printing resin that can stand up to the weight of testing and everyday situations can find a solution with Vorex resin.

MadeSolid introduced its durable Vorex resin for engineering applications last year but now there are more color options for your tough printing needs and we have them in stock!

In addition to the black and orange Vorex resin, white, clear and grey are available.  You can order all colors in either a smaller, 250mL test size or a 1L bottle here.  And remember, Made Solid Vorex resin is compatible on numerous SLA/DLP printers, including the Form1+ and B9Creator.

B9Creator 3D Printer – Kit or Assembled? The choice is yours

The B9Creator v1.2 HD 3D printer can be order and shipped throughout Europe as a kit or as a fully assembled, calibrated and tuned printer.


The kit has a lower price point and includes every part needed to assemble the B9Creator, including one resin vat.  However, resin is not included with the kit and must be ordered separately.  The kit does not include technical support other than the comments on the user forum on the B9Creator website.

It is also important to note that proper assembly on a level surface is critical for the performance of the B9Creator.  After careful assembly, the 3D printer must be calibrated and tuned.  Overall, the assembly, calibration and tuning could take up to 14 hours.  If you are interested in building the printer from the ground up, have time to spare and want to understand the construction process, the kit may be the right choice for you.


For professional users that want to start printing quickly, the assembled machine is an outstanding value.  It comes fully assembled, factory-calibrated and tuned by B9 technicians.  The quality controls in place at the factory ensure the printer will work right out of the box and since all the work has been done, you can spend your time printing rather than building.

In addition to saving time and assembly mistakes, this version includes one kilogram of B9 Cherry resin, two pre-coated B9 Vats, one calibration grid set and 1 hour of technical support in English over the phone.  When adding all this together, the assembled version truly is worth the additional cost.


Whether you are looking for a do-it-yourself option or want to start printing as soon as the printer arrives, Redresins provides the printer and supplies for next creations!

The burning question. Is resin really castable?

Lost wax casting has been around for over 5,000 years. However, 3D printing is changing the game for jewelers and dentists. Lower priced, high quality 3D printers and castable resins are opening the door for additive manufacturing in these fields.

In the past, subtractive manufacturing (carving or CNC milling) was common for making models for lost wax casting or other types of mold making. Now jewelers and dentists have more options and are saving time and money by investing in 3D printing.

For example, The Alternative Jewelry Shop in Kentucky is using the B9Creator and B9 casting resins to manufacture unique works of art. Customers are thrilled with the detail in the custom pieces and love being involved in the design process. With a 3D printer, The Alternative Jewelry Shop can create hollow models with undercuts that were impossible with traditional carving or CNC milling. They can show customers models before they are cast and are saving both time and money. In fact, in a mere 8 months they have already recuperated their investment in the B9Creator!

In Spain, a Redresins’ customer is using MadeSolid’s CastSolid resin to redefine his dental business. The demand for customized dental appliances and implants is growing and CastSolid is allowing him to reduce the customer wait time. He is able to use 3D printing to create replacement teeth, crowns, inlays and veneers, recreating fine details such as tiny grooves in each tooth.

Here at Redresins, we provide a wide range of tested, high quality castable resins to Europe and the rest of the world. Over 600 jewelers worldwide have used the B9 Red and Cherry resins and the results are impressive. B9 Black resin is also available for order. Additionally, we sell CastSolid, the new and improved version of FireCast, and customers and casters are pleased with the new formula. Although it is optimized for the Kerr casting process it works on a wide range of settings.

Now is your chance to experience the benefits of 3D printing and castable resin!

52 Ways to Clean Your 3D Printing Vat


In the past, we used a plastic or metal scraper to empty the unused resin from our 3D printing vats. But thanks to a customer suggestion, we now have another way of cleaning the interior surface of the vat. Who wants to spend time cleaning a scraper when a deck of playing cards offers a simple solution! The coated playing cards are sturdy enough to gently clean the bottom and sides of the vat yet flexible enough to avoid scrapes and damage to the delicate PDMS layer. And there are 52 cards in a deck so you can use a clean one each time, avoiding possible contamination from previous use.

When emptying and cleaning the vat, remember to hold the vat by the edges and avoid touching the printing surface on the bottom (both interior and exterior) as oil and fingerprints can interfere with a successful print. After pouring the majority of the liquid resin into a UV/light proof storage bottle, we find holding the playing card at a 45 to 60 degree angle to remove the remaining liquid resin from the bottom and sides works well. This liquid can then be added to the storage bottle. Remember never to use alcohol or a cloth to clean the inside of the vat and store the empty vat either in the printer or in a light proof container to avoid curing any remaining resin.

New B9 Black Casting and Prototyping Resin Revealed

B9Creation’s Shon Anderson shares the B9Creator and announces a new black resin for casting and prototyping at the 2015 uv-eb West Expo.

In addition to the fine slicing and outstanding quality of the 3D printer, Shon highlights the company’s philosophy on user flexibility. B9Creations gives customers the ability to adjust the printer and the software to create thinly sliced prints at 5 microns for lost wax casting as well as quicker curing, more durable prototypes. The company also has the software available for free download. This means you can experiment by importing existing models, crashing models together, adding supports or even creating your own model before buying a printer. Download the software and then hit preview rather than print.

On the supplies side, three types of resin are now available. The B9 Red and Cherry are targeted at the casting market whereas the new black resin contains more pigment and cures faster for quicker, prototyping projects. The black resin is also castable. Extra vats are also available so you don’t need to spend time recoating your existing vat and you can always have a spare or two available. Whether you are a jeweler, a dentist, or a designer, B9 has the printer and materials for you!
