开始使用自定义项
非常适合那些有创意的企业家，按需构建定制项目让您有机会在竞争中脱颖而出，提供来自现有产品的独特和原创项目。
毫无疑问，有各种各样的可定制物品，其中石版纸、书签和钥匙圈是开始创业的绝佳选择。让我们看看这是什么。
石蜡纸
这是用于打印 3D 照片的过程。这是通过打印一张纸来实现的，因为它有不同的厚度，所以会改变每个部分的不透明度，也就是说，通过纸的光量。这种技术创建了最终形成图像的光值（塑料颜色）的比例。
由于其多功能性，它是一个出色的可定制选项，允许打印客户选择的任何图像或照片。此外，它是制造灯具的理想技术。例如，Litophane Makers 网站为您提供了一种工具，可以将您的图像转换为使用这种技术制成的灯模型。
查看我们的文章，我们将在其中逐步说明如何创建您自己的石粉。
书签
对于那些阅读爱好者来说，书签是必不可少的，以免忘记阅读。可以打印各种书签设计，除了完美发挥其功能外，还能以有趣的方式装饰书籍，让您摆脱无聊的纸质书签。
您可能会在我们自己的文件浏览器中看到各种书签。
钥匙圈
拥有一个钥匙圈会让一些事情变得像一堆钥匙一样普通和无聊，我们都变得独特和个性化。
由于它们通常很小，因此它们是一种产生很少材料费用并允许您一次打印多个的选项。
灯
近年来，家居装饰品市场有所增长。买家似乎对这些能吸引来访者的原创且有趣的物品感兴趣。
灯可以设计成无数种方式，并且可以根据每个人进行定制，就是一个很好的例子。
打印灯具时，应注意一般需要中到大容量的打印机。这是因为，考虑到它们的纹理和设计，它们在部分打印然后粘合在一起时通常看起来并不美观，因为这会改变光线穿过灯的方式，并且一旦灯亮起，接缝就会更加明显。
狗屎袋容器桶
由于其实用性，这种类型的容器通常在携带宠物垃圾袋时非常有用。
这些容器有一个小孔，您可以添加一个挂钩，以便将它们挂在宠物的项圈或皮带上。
虽然有更简单的设计，但这种设计特别好，因为它模拟了通常与圣伯南狗相关的那些桶。此外，它们可以打印成不同尺寸以适合每只狗。
Spartan SD 卡夹
这是任何人都会想购买的物品之一。这个小战士的存在是为了让桌面免于杂乱无章，并防止我们所有的 SD 卡丢失。
珊瑚皂碟
这款可拆卸且易于打印的肥皂盒是一个很好的例子，说明您如何以经济实惠的方式制作出引人注目的设计产品，并且在销售时不会带来任何不便。
3D 打印的城市和废墟
微缩模型总是设法引起人们的注意，这与人类行为的本质有关（我建议调查原因）。许多品牌利用这些知识使他们的产品更加不可抗拒。这是一种在销售城市微缩模型时无疑是有效的资源，它们不仅用于装饰目的（作为装饰品、绘画或灯具），还可以用作玩具或制作模型。
在此处查看更多与桌面游戏的建筑物和微缩模型相关的模型！
雕像和纪念碑
这些模型再现了著名的地方、建筑物、雕像和其他纪念碑。我们可以找到从特别著名的建筑物的高度详细的建筑模型到巨石阵等遗址模型的所有内容。
除了装饰用途外，这些模型还被用作教育领域的教学工具，甚至经常用于棋盘游戏，特别是在角色扮演游戏中创造世界和故事。
花盆
它是 3D 打印世界中非常受欢迎的产品。有了这么多的模型，它们已经成为可以添加到任何空间装饰的设计项目。
最近，自动浇水的花盆变得流行起来。它们在商店里很难找到，这一事实使它们成为您在企业中提供的完美选择。
这些花盆通常设计成两部分：一个包含植物，另一个用作蓄水池。
无论是什么型号，由于它们是会与水持续接触并最终在户外使用的物品，因此应考虑两件事：一方面，它们的材料应符合上述条件，另一方面，3D 打印件通常在层之间留下微小的间隙，这可能导致泄漏。防止渗水的一种解决方案是用无毒的透明密封剂覆盖整个部件。
水培系统
水培系统使用不需要土壤使用的栽培技术。水分和养分的供应通过完整的营养液进行，为植物的发育提供了必要的条件。
有许多水耕栽培方法可以适应您想要种植的资源和植物种类。
构建这些系统的不同结构很容易打印，如果您有兴趣出售整个系统，您应该考虑在某些情况下添加额外的必要元素，例如泵或洒水器。
与花盆一样，您应考虑其材料应承受恒定湿度的条件。
花瓶
由于可以使用 CAD 软件创建奇特的形状和设计，花瓶是您开始使用打印机赚钱的绝佳选择，因为结果最终比任何市售的花瓶都更加现代和精致。
请注意，与花盆一样，需要绝缘体来防止泄漏。
复制品和道具
Replicas or props are recreations from some audiovisual production usually created to be exhibited or used in cosplays, such as armor or helmets.
When speaking about this type of product, most clients will expect professional-level finishes that try to reproduce every last detail. For this reason, this business option will require more time and effort than any other taking into account the printing (they are usually large pieces) and post-processing time. However, buyers of this type of work are often willing to pay large sums of money so in the end you will be able to make your time worthwhile.
D&D Miniatures (Dungeons and Dragons)
Miniatures for role-playing games like D&D are often small and have high-level details, which means that if you are really interested in making money selling such miniatures, you better have resin printers that will allow you to achieve these levels. They are one the funniest items to print and sell.
These pieces are often sold unpainted so that buyers can give them the details they see fit. This is good news as it will save you a lot of time and material in the post-processing of the pieces.
Jewelry (For Resin Printers)
The success of selling 3D printed jewelry requires creativity and quality to be able to compete in a market that is quite overloaded with artisans and hobbyists.
Since jewelry pieces are often small, only a small amount of material is required to print each piece. This implies a low-cost production that allows multiple pieces to be printed at once.
Given that these pieces require high levels of detail, to keep a high-quality standard you will need 4K or higher (6K/8K) resin printers.

Cell Phone Cases and Accessories
The market for cell phone cases and accessories is quite large and 3D printed versions are not left out. However, if you are interested in selling cases, it is best to focus on those unique, exotic or custom models that manage to attract buyers and are able to compete with the cheap versions already available in any store. A good example is this case with gears.
A very useful accessory in countless versions and designs that adapts to different needs and cell phone models is the cell phone holder. It is used to hold phones while using the GPS in the car and even when you want to record a video and there is no other person around to help you.
Cases for Raspberry Pi and Arduino
The Raspberry Pi is a series of low-cost single-board computers ideal for home electronics projects.
Since these plates are small, it is good to have cases or covers that, besides protecting the components, provide a more compact and functional appearance.
While selling these cases has its own potential, if you are also good with electronics, you could sell fully assembled Raspberry Pi projects.
You can see different models related to RaspberryPi in 3dSolved.
Eyeglass frames
This is an industry where 3D printing has also had an impact, making custom manufacturing of these items easier and cheaper. In the case of eyeglasses frames, being able to customize them ensures a perfect fit and this is what many customers might prefer.

Custom Bottle Carrier
This bottle carrier is a handy item for those who need to carry their bottles or make a gift.
If you are interested in selling this item, you should first test the strength of the structure to ensure that the print is strong enough to support the weight of the bottles. To that end, the creator of this design suggests printing the main body with 100% infill.
Headphone Holder
We all have headphones, and without a doubt more than once have spent a long time trying to untangle them, only to have them get tangled up again when we put them in our pocket or backpack.
These headphone holders are certainly an option that would sell well as they are little, quickly to print, do not require much material to be manufactured, and would make life easier for many (or perhaps I am exaggerating).
Cookie Cutters
3D printing also seems to have reached the cooking world with the manufacturing of cookie cutters.
Once again, designing and printing your own items allows you to create new and original designs that will catch buyers’ attention.
As they are items that will be in direct contact with food, you must be careful with the material that is used. PETG is the most recommended one since it is used, for instance, for the manufacturing of bottles.
You may see different cookie cutters in 3DSolved.
Fidget Toys
Fidget toys are little toys that fit in the hand and can be easily carried in a pocket. Due to their constant and repetitive movements, they often help release stress and anxiety.
This type of product is easy and cheap to print and it often catches the eye of customers.
In this video, you will see several examples of this kind of toy.
Mini Wheels for Console Controllers and Joysticks
For those car game lovers who do not want to spend large sums of money on steering wheel-shaped controllers, this is a much cheaper option as well as functional. Furthermore, the good news is that there are designs for the joysticks of the different existing consoles.
Electric Guitars
Historically, guitars have been made of wood. However, 3D printing comes to revolutionize another field by bringing the possibility of printing fully functional guitars.
It should be taken into account that the difficulty of this type of product does not lie only in the printing process but also in the post-processing and assembly work, which requires certain knowledge of guitar lutherie.
How much money should you expect to make selling 3D prints?
When determining the profit that should be expected from the sale of this type of items, there are several factors that will play their part.
Everything is connected. Time, cost of labor, designing, printing, assembling, packaging, and logistics will be involved when deciding if the final cost of the product allows you to make profits in the end.
Another aspect to take into account is the added value of the product, which depends to a large extent on the object in question and not on the technology that is used. If a given object is pretty popular, then competition makes it barely possible to cover the costs. However, when it comes to unique objects of a particular design, customers do not hesitate to pay higher prices if they are interested in the product.
In this video you will see how they experimented when manufacturing an item in small sets in order to assess what the profit margin profit was, and if it was really convenient to use this technology for its manufacturing. The person in question published the article on Etsy and, considering all the factors that I mentioned above, ended up with a 50-cent profit per dollar, that is to say, about half the initial cost of each item. To conclude, for such a size of production, this is a profitable business and manufacturing method.
