Smoothing the rough surface

Hello everyone. My name is Thomas and I am very new to this 3D scene but still very glad to be here. I would like an input from everyone about something. Recently I purchased MakerBot printer and printed something simple. At first glance I was amazed by the finished product. I'm sure you've felt the same way. But on a closer observation and physically picking up the object, I realized that the outer surface was rough (or more like layered). Now my question is what is your solution to this rough surface? I tried sanding to smooth it out. But I'm pretty sure there's a much starter way to tackle this problem. Thank you have let's make something!

Servos motion not smooth

Hi, im trying to program my servo to do a simple sweep (smooth motion). but instead it jerks a small degree everytime. the code i've used : #include Servo myservo;  // create servo object to control a servo void setup() {   myservo.attach(9);  // attaches the servo on pin 9 to the servo object } void loop() {   myservo.write(10);                  // sets the servo position according to the scaled value   delay(1000);                           // waits for the servo to get there   myservo.write(150);                  // sets the servo position according to the scaled value   delay(1000); }

Any substitute for Smooth-Cast 300? Answered

We have our own homegrown substitute for Oomoo thanks to the local boy genius Mikey77 But is there any substitute for it's companion product, the very expensive ($100/gallon), two part liquid plastic stuff called "Smooth-Cast 300"? Does anyone know of a way to mix an inexpensive something up and pour it into a mold and have it harden up into a strong thing?  It doesn't have to be as invincible as Smooth-cast, but .. is plaster the only option? Update:  What am I casting?  I found a really great ornamental tile at Habitat for Humanity and want to make copies of it Update:   I'm wondering now, what if I used something from the wall/flooring department, like Mastic?  Its about $34 for two or three gallons.  It fills gaps and hardens to such a degree that it can't be chiselled easily.  I may try this. Update:  Tried mastic, it works but takes far too long to dry, on the order of three days or longer...  Maybe if I mixed in some corn starch (ala oogoo?) Thank you -foo

How does Smooth-On's Feather Lite urethane resin compare to their Smooth-Cast 300 resin?

I want to cast my original horse sculptures, but since I don't have a roto-cast machine, I'll have to solid-cast the models. I'm a fan of draft horses, so my 1:9 scale horses will be rather large and bulky. This would be heavy if I did a solid-cast with normal resin, which would make shipping prices escalate, so I'm thinking the feather-lite would be a better choice. I'm worried about its ability to replicate fine details, and in the model horse hobby, it's all about the fine details and the quality of the cast. What is the quality of the resin like compared to their other resins, and how well does it replicate the original sculpt? Any help is appreciated! Thanks in advance!

What is a smooth, or "rounded" aggregate, like sand, but NOT abrasive ?

I made an hourglass as a prop for a local production of "The Wizard of Oz".  The "witch" (the actress') still has it at her  home.  The "glass", which s actually plastic, & made of sections cut from 4 plastic goblets- is becoming less clear because the white sand I used is fogging up the surface with very fine scratches.  I'd like to replace this sand (that I got from a craft store, like Joann's) with an aggregate that has smooth round pieces, not rough ones.  These wont be so scratchy, and will also be less apt to cram together and clog the narrow passage from the top chamber to the lower one.  I googled these words, and got some very technical info about the science of manufacturing concrete and plastic products, but nothing I could use to find or even name what I could buy and use.  ALSO, is there a best compound for polishing the inside of the "glass" to restore the original clarity?  In other things, I've used brass polish, and even toothpaste!

What is the best way to grind glass, somewhat smooth? Answered

Now before you rush to write down an answer let me tell you the details! The chunk of glass is 28 inches wide by 28 inches long and 2.5 inches tall. Composed of 160 painstakingly cut strips of glass that have been glued together into a jumbo block. Now try as I might, when laminating things together of ever so slightly different size together you are going to get high and low spots - And yes, this would have been soooo much easier a job if I had smoothed out the rough edges before laminating - Pesky hind-sight. Unfortunately my planer doesn't seem to work so well on glass, who knew :) Anyway, I will post some pictures to give you an idea of what it is, that has to be ground down. First off • It does not have to be perfectly smooth • A mottled surface would actually be appreciated • It is not going to be a lens of any kind, all though light will be transmitted through it. I have the following tools, but first - No I am not taking it 1700km to have it kilned. No, the local glass shop seems to have less tools then I do, at least in this scale. • Angle grinders • belt sanders • orbital sanders - but really? On the back side I used the angle grinder, with a metal grinding bit. Not to bad really all though the edges were taking a pounding. This was prior to applying resin and woven cloth, to give the glass a bit of tooth and reduce the high edges. This is for an instructable I am working on.

need a jig for cuttin styrofoam straight/smooth surfaces?

I'm trying to get into lost foam (aluminum) casting, so I just build a styrofoam cutter ("frame" with a hot-wire). It's pretty difficult to handle because it melts trough the styrofoam so quickly and it's hard to hold perfectly straight and every movement makes an impression in the styrofoam part. I need some ideas on how to make a jig that makes it easy(er) to make smooth surfaces in the styrofoam part, I was thinking something that adjusts the distance between the hot wire and the table/surface and then just slide the styrofoam across the table/surface through the hotwire for making plates (easy), but I need to be able to change the distancee between the surface and the hotwire for different thinknesses but also somehow be able to make angles and hopefully also somehow ROUND PIECES AND CYLINDERS :o hope you can give me some inputs :D and even better some pictures, drawings and links thianks!

Sanding wood smooth without losing rustic saw marks

I've searched for an answer but can't find one. Hoping someone can help me out with this. I recently picked up some old wood boards, about 3" thick, 4' long, and a foot wide. They're fairly old and have that warm weathered look of old raw wood. On one side you can see the nice circular saw marks from when they were milled. They're also very splintery, and I got plenty of splinters when I moved them. My goal: preserve their rustic beauty while making them into usable wood for furniture. I want the surface smooth enough that splinters aren't an issue. How can I sand the boards so they are smoother a micro level, but don't lose the beautiful saw marks? Ideally I'd keep that weathered color, but I suspect I'll lose at least some of that due to sanding and will have to fake it with stain. Thanks a ton for any help! Josh

How do I make a crumpled dollar bill be smooth like new again? Answered

This may sound like a silly question, but if your main currency is not US dollar like me... then this is a serious matter.. Ok here's the case.. a couple weeks ago a friend came to visit me in Jakarta and he left his pouch that contains all his cards and money at the plane cabin. So all he got in his pocket was 2 x $20 and 1 x $10 ($50). Because they were crumpled dollar bills so the money changer wont accept his money, even if someone willing to take his dollars they give such loooooow rate. So, being a good friend, I took his dollar and give him my IDR (Indonesian Rupiah). So he can at least pay for his hostel and dinner, since he wont let me pay for his expenses (he could just borrow my money and pay me back later, but he's too proud to do that :p). So... now I'm left with crumpled dollar bills on my hand.. USD $1 = IDR 8500ish , so $50 is around IDR 425,000. But because they are crumpled.. so the highest rate I could get for $1 is IDR 7000, that means I'll get max IDR 350,000... IDR 75,000 lower than I should have get (thats around $9 difference). But if I can only get IDR 6500 or IDR 6000 for one dollar... then meh you do the math how much I'll get and the difference. Unless.. I can find a way to make those crumpled dollars smooth and sleek as new again. Well not exactly as new, but close enough.. Any kind of suggestion or tips are greatly appreciated :)

Putting an end to flickering LED's on mains

Greetings everyone! It's the time of year when colorful twinkling lights adorning nearly every structure you can see. LED's have become more popular as of late, and from an energy standpoint that's good. I know most people can't see a 60Hz flicker but I can, and it's quite unpleasant to sit across from a tree full of LED's all doing the same on-off-on-off nonsense.  I am fortunate to only get headaches though, other epileptics I've known have actually had AC LED's trigger seizures. So what can be done about this? We bought LED strings before thinking about flicker and have since replaced them with incandescent ones, but I've still got all the LED strings in the closet. I'd really like to be able to use them.  Perhaps I could fashion a device that acted as a middleman between the outlet and the plug on the lights that would smooth the incoming current? I have two ideas for this:  1.  Filter incoming current with an RC circuit 2.  Rectify the mains voltage I'm curious if anyone else has attempted, solved, or even just noticed this frequency problem? I don't mind re-inventing the wheel, but I'd rather not build it square. Happy holidays! **yes, I just said happy holidays. Deal with it. :)

[Question about diffusing light] ... Making a Tron costume. How can I diffuse the LED lights to look more smooth? Answered

Alright, so I'm making a Tron Legacy outfit for NY Comic Con in a few days. It's a spin-off of Kevin Flynn's black robe, which is basically a robe with a light on the borders of it. Pic below. Now, for many reasons, I'm using LED strips instead of EL wire. The problem is that the LEDs are so bright that each individual light shines clearly through the white shower curtain that I'm using. Do you guys know of any really good ways to diffuse this light so that it looks smoother? When I lift the curtain higher from the strip, maybe about an inch, it becomes more diffused. But since I will be sewing this to my garment, I'm not 100% sure how to keep the shower curtain higher above the LEDs at all times. Any enlightenment would be greatly appreciated. Thank you.

How do I get a solid balloon shape? Using a 3 Foot diameter latex balloon, need to fill with a solid, smooth material?

First:  Thank You Already for Considering helping me. I need the shape of the Inside of the balloon - not the outside like papermache'. I tried Canned Foam Insulation "Great Stuff" brand; but it didn't expand and solidify.  Then I need to cut it in half to get a hemi-sphere / hemi-balloon shape.  A shape like half an egg, but 30" long, 19" wide, and 9" deep if laid on the flat side. Will Gorrilla Glue puff up and stretch out the balloon?  Is there some kind of expanding urethane that doesn't need free air to cure? Will a rubber mold making liquid like Vytaflex fill a balloon to it's "real shape" and cure inside without air?;=1 is a video of making a sink mold from an existing vessel sink.  But I don't have an original of this shape to make a copy of. Ice isn't permanent enough, but would be the perfect slick surface texture.  I don't have the tools to cut a 30x19" sphereoid in half neatly. The goal is to get a solid shape with a smooth surface to use as a mold for pouring material over to achieve a "bowl" shape with a very smooth interior surface and a hand formed outer surface. thanks again

Hi there. While testing some code on three servos using my picaxe 18m2 project board I initially had them powered of the 4x1.5v battery pack. This was working smooth enough, but because I eventually plan to power seven servos (for a robot arm project) I thought I'd try using a 7.5v wall transformer but they didn't seem to like this as the smoothness of movement was gone as they slowed and sped up and were jittery.  Is the 7.5 a bit much, a few resistors maybe? Or prehaps capacitors would smooth things out. I'm not overly electronically gifted, robot builders guide is all I've got to go on. cheers. john.
