This is an excellent question. The answer to this is going to be pretty long. So kindly bear with me.

The thing you have to know about conventional jewelry manufacturing is most often, the jewelry is made by using a process called investment casting or lost-wax casting. Recommend reading this article for a background: Investment hd casting

Once you have read that, I am sure you would have understood that there are several properties you need from the pattern you will make a mold from. Ideally you would want a material with the following qualities :
You need to have a good surface finish of the jewelry so that it shines better and is aesthetically more pleasing. Therefore it is of paramount importance that your pattern has a good surface finish. You need to use a substance which burns off quickly without much residue. It is durable in variable conditions of temperature. You don't want your pattern to be made of a material which distorts easily. Should be easy to transport.
The material which most often meets these requirements is wax. Although, it sometimes has issues on the 3rd parameter.

The usual manufacturing process (I am not sure if the OP knows how the jewelry manufacturing process works, but for the ones who might now know, here is how it goes. Bold indicates the stage in the manufacturing process):   3d printing prototyping service chandigarh kochi - sla technology
1. Design of the part in a CAD/CAM software.
2. Prototyping by use of a CNC machine to cut a block of wax in the shape desired from the CAD file.
3. Urethane casting [Optional only if multiple copies are needed] : Making urethane molds to make multiple wax model copies.
4. Casting: Setting up of a "Christmas tree" where these models are attached to a runner and then dipped in a ceramic slurry.
5. Pouring of the liquid metal into the runner. The metal burns and evaporates the wax and solidifies in the desired shape.
6. Surface Finish: Minor finishing required.

This is in relation to the S200 & S250, not sure about the D255.
It appears they all use the same build table as the largest model.
However the build area is restricted to that of the models specs.

I you could have a full width plate to place at the front & a couple down the sides.
These could be of a different colour & flat. Then you can save the strips for the build area.

ABS contains styrene which is indeed soluble in limonene so you would have to be very careful of over-treatment. I don't believe PLA contains any styrene content, could this be a more suitable material to print with HIPS?

It will be interesting to see whether limonene treatment will affect the ongoing stability of the ABS - perhaps it permeates and weakens the structure over time?

UP Plus / New Spool
« Last post by Tdotcom on May 16, 2017, 07:25:04 AM »
Hi Group
I am a real newbie at 3D printing. I have only just used my first roll of filament.  I have put my new spool on and according to the instructions I need to select 'New Spool' under Maintenance.  My problem is that I do not have the 'New Spool' option?  I have an Up Plus 2 printer and Up Software v1.7.3.0.  The software is up-to-date, just checked.  I cannot find the option anywhere else in the program, so I keep getting the 'Printer is short of material' error message, which is annoying.  I am a teacher and have just starting doing 3D printing with my students so any help will be greatly received.  Thank you very much.
Practical Explanation ( For Example ) :- `1st of all can you tell me every single seconds detail from that time when you born ?? ( i need every seconds detail ?? that what- what you have thought and done on every single second )

can you tell me every single detail of your `1 cheapest Minute Or your whole hour, day, week, month, year or your whole life ??

if you are not able to tell me about this life then what proof do you have that you didn't forget your past ? and that you will not forget this present life in the future ?

that is Fact that Supreme Lord Krishna exists but we posses no such intelligence to understand him.
there is also next life. and i already proved you that no scientist, no politician, no so-called intelligent man in this world is able to understand this Truth. cuz they are imagining. and you cannot imagine what is god, who is god, what is after life etc.
for example :Your father existed before your birth. you cannot say that before your birth your father don,t exists.

So you have to ask from mother, "Who is my father?" And if she says, "This gentleman is your father," then it is all right. It is easy.
Otherwise, if you makes research, "Who is my father?" go on searching for life; you'll never find your father.

( now maybe...maybe you will say that i will search my father from D.N.A, or i will prove it by photo's, or many other thing's which i will get from my mother and prove it that who is my Real father.{ So you have to believe the authority. who is that authority ? she is your mother. you cannot claim of any photo's, D.N.A or many other things without authority ( or ur mother ).

if you will show D.N.A, photo's, and many other proofs from other women then your mother. then what is use of those proofs ??} )

same you have to follow real authority. "Whatever You have spoken, I accept it," Then there is no difficulty. And You are accepted by Devala, Narada, Vyasa, and You are speaking Yourself, and later on, all the acaryas have accepted. Then I'll follow.
I'll have to follow great personalities. The same reason mother says, this gentleman is my father. That's all. Finish business. Where is the necessity of making research? All authorities accept Krsna, the Supreme Personality of Godhead. You accept it; then your searching after God is finished.

Why should you waste your time?
all that is you need is to hear from authority ( same like mother ). and i heard this truth from authority " Srila Prabhupada " he is my spiritual master.
im not talking these all things from my own.

in this world no `1 can be Peace full. this is all along Fact.

cuz we all are suffering in this world 4 Problems which are Disease, Old age, Death, and Birth after Birth.

tell me are you really happy ?? you can,t be happy if you will ignore these 4 main problem. then still you will be Forced by Nature.

if you really want to be happy then follow these 6 Things which are No illicit s.ex, No g.ambling, No d.rugs ( No tea & coffee ), No meat-eating ( No onion & garlic's )

5th thing is whatever you eat `1st offer it to Supreme Lord Krishna. ( if you know it what is Guru parama-para then offer them food not direct Supreme Lord Krishna )

and 6th " Main Thing " is you have to Chant " hare krishna hare krishna krishna krishna hare hare hare rama hare rama rama rama hare hare ".
If your not able to follow these 4 things no illicit s.ex, no g.ambling, no d.rugs, no meat-eating then don,t worry but chanting of this holy name ( Hare Krishna Maha-Mantra ) is very-very and very important.

Chant " hare krishna hare krishna krishna krishna hare hare hare rama hare rama rama rama hare hare " and be happy.

if you still don,t believe on me then chant any other name for 5 Min's and chant this holy name for 5 Min's and you will see effect. i promise you it works And chanting at least 16 rounds ( each round of 108 beads ) of the Hare Krishna maha-mantra daily.
Here is no Question of Holy Books quotes, Personal Experiences, Faith or Belief. i accept that Sometimes Faith is also Blind. Here is already Practical explanation which already proved that every`1 else in this world is nothing more then Busy Foolish and totally idiot.
every `1 is already Blind in this world and if you will follow another Blind then you both will fall in hole. so try to follow that person who have Spiritual Eyes who can Guide you on Actual Right Path. ( my Authority & Guide is my Spiritual Master " Srila Prabhupada " )
if you want to see Actual Purpose of human life then see this link : ( triple w ( d . o . t ) asitis ( d . o . t ) c . o . m {Bookmark it })
read it complete. ( i promise only readers of this book that they { he/she } will get every single answer which they want to know about why im in this material world, who im, what will happen after this life, what is best thing which will make Human Life Perfect, and what is perfection of Human Life. ) purpose of human life is not to live like animal cuz every`1 at present time doing 4 thing which are sleeping, eating, s.ex & fear. purpose of human life is to become freed from Birth after birth, Old Age, Disease, and Death.

 I cleaned the nozzle and the little metallic wheel that pushes the filament into the extruder. After that it worked fine. The information on how to clean the nozzle is found in the manual at
UP BOX / Machine worked fine, now nozzle runs into board no matter what settings

Have a new Upbox+ that worked fine for the first 3 print jobs, then clogged up. Ran a 1.5 mm drill through nozzle to clean it, now nozzle runs into board no matter what settings? Have done auto calibration, nozzle check, changed nozzle height from 208 to 215, still hits perf board and burns a groove in it? Any ideas?

I have had a lot of problem with air printing. I don't know if the nozzle gets blocked. I love the finished product when it works but it seems it only works 50% of the time. I have pressed extrude but nothing is coming out. I am in a school and want to get the students printing their creations. I am not an engineer and don't know how to fix it.

I have the same problem, at first I thought it was the extruder was too hot, as it was grinding into the filament stopping feeding.

But I think it has to do with the 1kg rolls I am using, I did not have a problem with the 500g roll it came with.

Doing another print right now. We will see.
UP BOX / Extruder stopped extruding halfway through print
« Last post by brypar on April 07, 2016, 07:42:09 AM »
I woke up this morning to see that the extruder had stopped extruding. At first I thought I had run out of filament but this wasn't the case. The printer is brand new (1 day old) and successfully printed 2 earlier items. The print time was 15 hours.

Any ideas? Long shot, but can the print be started where it stopped even though it ran for over an hour printing nothing?
